7620e96171 expose whether a volume replica is backed by remote storage, and prefer local replicas (#11105)
* expose whether a volume replica is backed by remote storage

Volume locations returned by lookups do not indicate whether a replica
has been tiered to remote storage. Readers cannot distinguish a local
replica from a remote-backed one, so they may hit a remote-backed
replica first even when a local replica is available.

Add DataInRemote to the lookup location message, populate it from the
master's volume info, and carry it through the wdclient vid map so
clients can prefer local replicas when resolving chunk locations.

* wdclient: prefer local volume replicas over remote-tier replicas on lookup

LookupFileIdWithFallback (and the publicUrl variant in FilerClient)
didn't honor the DataInRemote flag when shuffling URLs, so the
DataInRemote patch only took effect in LookupVolumeServerUrl. Apply
the same ReorderToFront(localUrls) to sameDcUrls/otherDcUrls so
non-remote replicas stay at the front, matching the existing vidMap
convention.

* wdclient: propagate DataInRemote across tier transitions on existing replicas

When a volume is tiered to remote storage or a remote-backed replica is
restored locally, the cached DataInRemote on the same volume-server URL
stayed at its old value because two pieces of state never updated:

* master_grpc_server.go only split newVolumes and (already-tracked) volumes
  into NewVids vs RemoteVids. ChangedVolumes went straight to NewVids, so
  the broadcast announced the re-classified volume as a fresh arrival and
  the client had no way to tell whether its existing cache was stale.

* vid_map.addLocationToMap early-returned when an entry already had the
  same URL. A tier transition reports the same URL with DataInRemote
  flipped, so the cached entry stayed at the old classification.

Wire both sides together: ChangedVolumes now go through the same IsRemote
split as newVolumes, and addLocationToMap replaces the existing entry in
place when the URL matches but DataInRemote has changed. The server
reference key only depends on URL/grpc port, so the refcount does not
move across the flip.

Adds vid_map_remote_transition_test.go covering the local->remote and
remote->local paths so the in-place update and the cache-key stability
are pinned by tests.

* wdclient: prefer local replicas across data-center boundaries

The previous local-first ordering hoisted local URLs to the front of each
data-center bucket separately, then concatenated same-DC before other-DC.
That meant a same-DC remote replica could still be tried before an
other-DC local replica even though the local one would answer cheaply.

Reorder once across the full candidate list: concatenate same-DC and
other-DC first, then ReorderToFront pulls every local replica to the very
front while preserving the DC preference inside each tier. Apply the same
ordering in all four lookup paths so the cached vidMap, the
LookupFileIdWithFallback provider path, FilerClient.GetLookupFileIdFunction
(PublicUrl-preferred variant), and the deprecated filer.LookupFn all agree:
- weed/wdclient/vid_map.go (LookupVolumeServerUrl)
- weed/wdclient/vidmap_client.go (LookupFileIdWithFallback)
- weed/wdclient/filer_client.go (LookupFileId)
- weed/filer/reader_at.go (LookupFn)

Strengthen the existing local-first tests: vidmap_client_localfirst_test
now asserts both endpoints are present (not just the local one is first),
and slice_test asserts an exact match instead of accepting two orderings.

Add TestLookupFileIdWithFallbackGlobalLocalFirst to pin the cross-DC
ordering invariant: any local replica (same or other DC) precedes every
remote-tier replica; within each tier DC1 precedes DC2.

Add docstrings to ToVolumeLocations, ReorderToFront, LookupVolumeServerUrl,
LookupFileId, GetVidLocations, GetLocations, LookupFileIdWithFallback, and
updateVidMap so the touched lookup paths are described in one place.

* topology: broadcast tier transitions on existing replicas

When a volume replica is tiered to remote storage or restored locally, the
wdclient's cached DataInRemote went stale: every connected client kept
preferring a remote-backed replica over a freshly restored local one, or
demoted a freshly tiered remote replica. The fix in commit 116982595 routed
ChangedVolumes to NewVids/RemoteVids on the master, but ApplyVolumeChanges
returned only fresh arrivals and previously servable replicas. An existing
replica whose IsRemote() classification flipped was neither, so it never
reached the broadcast loop and the wdclient never learned.

Make Disk.doAddOrUpdateVolume return a third signal -- tierTransition --
true exactly when an existing replica's IsRemote() flips. ApplyVolumeChanges
treats that as an arrival so the existing SendHeartbeat routing loop now
sees it. Add a master-side end-to-end test covering local->remote,
remote->local, no-op re-reports, and a mixed heartbeat that only announces
the tier transition.

Also add docstrings to LookupFileId, wdclientLocationsToPb, and
LookupVolume where the prior change touched their bodies.

* topology: broadcast tier transitions received through full reconciliation

The previous commit added tier-transition routing on the ChangedVolumes
delta path, but that is not the only way a re-tiered replica reaches the
master. After a digest mismatch the volume server resends a full Volumes
list, and SyncDataNodeRegistration applies the new IsRemote() classification
silently -- the changedVolumes return value was being thrown away. The
master therefore never broadcast NewVids/RemoteVids, and a wdclient connected
during the recovery kept the stale DataInRemote until it lost contact with
the master.

Surface the changed set through UpdateVolumes.changedVolumes (now covering
both ReadOnly flips and tier flips) and SyncDataNodeRegistration, then route
it through NewVids/RemoteVids in SendHeartbeat the same way the delta path
already does. Add an end-to-end test for the full reconciliation path.

* master: keep an EC volume's locations in the volume lookup

The nodes that answer for an EC volume hold shards, not a volume record,
so asking them for one fails. Dropping the location on that failure
emptied the result and turned every EC read through the master's HTTP
lookup and fid redirect into a 404.

Treat an absent volume record as a local read and keep the node in the
answer. The per-node conversion moves into topologyLocation so the EC
case is covered by a test.

* wdclient: replace a tier-flipped location without writing under a reader

GetLocations hands back the entry's own slice and the caller walks it
after the read lock is dropped, which is why every other mutation here
builds a new slice. Writing the flipped replica into the array in place
raced LookupVolumeServerUrl, reported by -race.

Copy the slice, swap the one element, and publish it.

* master: keep a remote volume on NewVids for older clients

Moving remote-tier volumes out of NewVids and into RemoteVids alone is a
wire break in the wrong direction. A master upgraded ahead of its filers
and mounts -- the usual order -- announces a tiered volume only on a
field the older client ignores, so the volume drops out of that client's
vid map entirely and reads for it fail.

Announce every volume on NewVids and repeat the remote-tier subset on
RemoteVids, so a new client still learns the tier and an old one keeps
the location. The routing moves into announceVolume, which the heartbeat
paths and their tests now share instead of each restating it.

On the client, RemoteVids no longer needs a second write per volume: the
tier is settled before anything is added.

* topology: split the volume snapshot by tier without copying the records

ToVolumeLocations runs on every KeepConnected, so a filer or mount
connecting made the master allocate a full VolumeInfo per volume per node
just to read four bytes of id off each one. AppendVolumeIds exists to
avoid exactly that.

Extend it to fill the remote-tier list alongside the full one, and use it
again in the snapshot.

Claude-Session: https://claude.ai/code/session_01FcSp6quCaxQ1cb3Vx7o9fW

* wdclient: keep the data-center preference ahead of the local-first ordering

Hoisting every local replica to the very front puts an other-DC local
read ahead of a same-DC remote one. When the remote tier sits in the same
region as the replicas -- the common arrangement -- that trades an
in-region GET for a WAN round trip and costs more than the remote read it
avoids.

Reorder inside each data-center bucket instead, so local still wins among
equals and the data-center preference still wins overall.

Claude-Session: https://claude.ai/code/session_01FcSp6quCaxQ1cb3Vx7o9fW

* operation: pick the read replica from one list

The local-preferring lookup built a list of local URLs and then branched
on whether it was empty, duplicating the random pick. Fall back by
filling the same list with every replica instead.

* master: rename VolumeListRequest.without_volumes to topology_only

The field shapes the reply rather than selecting volumes, and it leaves
out the ec shards too, which the old name denied. Match the message's

A topology_only request that also names a collection or volume ids

Chris Lu 88c873ecd4 ec: uniform shard block layout (#10932)
* ec: uniform shard block layout

An EC volume is striped as 1GiB blocks until less than one row remains, then
1MiB blocks, and consecutive blocks land on different shards. With ec.encode's
-fullPercent 95 against the 30GiB default limit, ~30% of every volume sits in
that 1MiB tail, so a 4MB filer chunk there is five stripes on five servers.

New encodes now use one block per shard, sized ceil(datSize/dataShards) rounded
up to 1MiB and recorded in the .vif (EcShardConfig.block_size, also carried by
the .ecsum manifest). A needle now maps to one shard unless it is larger than
the block or straddles a boundary. The chosen size equals the legacy layout's
padded shard length for every input, so shard sizes, capacity math, and the
shard-size credibility checks are unchanged; only the byte placement moved.

Reads, decode, and scrub resolve the block sizes from the volume's .vif;
absence keeps the legacy interpretation, so existing EC volumes read exactly as
before. Rebuild is layout-agnostic. weed fix -ecx recovers the layout from the
.vif, else the .ecsum sidecar, and with neither de-stripes under both candidate
layouts and keeps the one that indexes more valid needles.

Same change in the Rust volume server, which now also streams the encode in
256KB sub-batches like Go instead of allocating whole blocks, and computes the
large-row count as shardSize/largeBlock to match Go on exact multiples. On a
26MB fixture both encoders produce byte-identical shards, and a Go-written .vif
parses in Rust with the block size intact.

* ec: resolve the rust ecx rebuild through the recorded layout

The Rust rebuild path regenerated a lost .ecx by scanning the logical .dat
through a hand-rolled pure-1MiB striping, which was already wrong for legacy
volumes with large-block rows and is wrong for any uniform volume with a block
past 1MiB. Route the scan through locate_data with the .vif-recorded block
size, the same mapping the read path uses. Also seed the new tests' random
data instead of the deprecated global math/rand.Read.

* ec: fail the Rust ecx rebuild on any shard read error

A read error mid-scan published the entries collected so far as a
successful .ecx, and read_at's byte count was ignored so a legal short
read passed as complete — a truncated or failing shard could produce a
silently incomplete recovery index. Exact-read semantics in
read_from_data_shards, error propagation in the needle walk, and a
truncated-shard regression test.

* ec: fail the mount on an unreadable or malformed vif

Both servers silently fell back to the legacy layout when an existing
.vif could not be read or parsed. Every new encode records a positive
uniform block size there, so the fallback mounted the same shards with
legacy offset math and could return wrong data. Absent stays legal
(legacy volumes predate the sidecar), and a zero-byte stub still reads
as absent (Go's MaybeLoadVolumeInfo convention, now mirrored in Rust);
a present-but-unreadable or malformed .vif fails the mount instead.

* ec: bound the reconstruct fan-out of one needle's intervals

A degraded interval fans out a read to every reachable shard location, each
with a buffer the size of the interval. Reading a needle's intervals in
parallel multiplied that by the interval concurrency: a needle spanning 8
blocks could hold 8 x MaxShardCount remote reads and buffers at once, where
the sequential version peaked at MaxShardCount. Give each needle a single
reconstruct budget its intervals share, held for the buffer's lifetime, so
separate reads stay independent but one read cannot multiply its own
fan-out.

* ec: drop the duplicated shard-size formula

calculateExpectedShardSize reimplemented the padding rule that
UniformBlockSize already owns — TestUniformBlockSizeMatchesLegacyShardSize
asserts the two agree for every input — so a change to the rule would have
had to be made in both. Defer to the helper, keeping the historic answer for
an empty .dat.

* ec: resolve the shard block layout from whatever records it

Four places still answered the layout question by inference when a record of
it was available, or accepted an answer that was not one:

- A mount with no .vif defaulted to the legacy layout; the bitrot sidecar
  records the same config at encode time, so take it when present, as
  weed fix -ecx already does. The vif itself is now parsed once per mount
  rather than twice.
- The Rust ecx rebuild derived its row count from the padded shard extent,
  which under the legacy layout reads a shard that is an exact large-block
  multiple as one row too many. Pass the encode-time .dat size from the .vif
  and keep the extent as the fallback.
- weed fix -ecx read the block size outside the EC-config guard (collapsing
  the unknown sentinel into a definitive legacy), only wrote the recovered
  layout back when the .vif was absent rather than unusable, and broke a
  scan tie by candidate order instead of the documented reach.
- The uniform layout tripped writeDatFile's large-block ambiguity guard,
  which cannot apply when the large and small blocks are the same size.

* ec: give the index-recovery tests a parseable vif

The fixtures wrote the literal bytes "volinfo" as the source .vif and the
recovery copies it verbatim, so the receiving server then mounted the volume
from a .vif it could not parse. That used to pass by silently defaulting to
the legacy layout; a mount now refuses a vif it cannot read, which is what
the tests were exercising all along without meaning to.

* ec: validate the layout a vif records, not just its syntax

Review follow-ups on the mount-strictness change:

- A .vif can parse and still record a block size no encoder could have
  produced (negative, or not a whole number of small blocks). Both servers
  took it and mapped every read through it. ValidateBlockSize / the Rust
  mirror now refuse the mount, the same way an unparseable vif does; 0 stays
  valid as the legacy two-tier layout.
- The bitrot-sidecar fallback accepted parity_shards == 0 and summed the
  counts in their own width, so values near the ceiling wrapped past the
  MaxShardCount bound. Require both counts and sum in a wider type.
- weed fix -ecx treated a config with only DataShards > 0 as usable, so a
  half-written .vif suppressed the recovery paths AND survived the rewrite.
  Require a complete, in-range config before trusting it.
- Returning the vif-load error left the .ecx and .ecj descriptors open;
  repeated mount attempts on malformed metadata could exhaust them.

* ec: refuse to act on a layout the metadata does not establish

- The worker encode only logged a failed .vif write and skipped it in the
  distribution set, and treated the .ecsum write as best-effort. A worker
  whose disk filled after the much larger shards landed could still
  distribute, mount, verify shard inventory, and delete the source replicas —
  leaving holders with shards whose geometry nothing records. Both writes and
  both inclusions are encode success conditions now.
- A generation-matching .ecsum that disagreed with the .vif geometry only
  disabled checksums in Go, and in Rust was not compared at all, so
  protection stayed On while reads used the other layout. Both files record
  the layout their generation was encoded with, so a disagreement now fails
  the mount.

* ec: reject an invalid recorded block size in weed fix -ecx

A .vif with valid shard counts but a negative or unaligned block size was
marked usable: a positive invalid value pinned the scan to a geometry that
de-stripes to garbage, and a negative one ran the dual scan but left the
invalid .vif in place afterwards. Validate it with the same rule the mount
applies, and when it fails leave the layout unknown so the scan recovers it
and the file is rewritten.

* ec: validate the sidecar layout weed fix -ecx recovers from

The .ecsum fallback was taken on DataShards > 0 alone, so a CRC-valid
sidecar carrying the wrong generation, an incomplete ratio, or an unaligned
block size would pin the reconstruction to one incorrect uniform-layout
candidate instead of letting the dual scan decide. Require generation 0, a
complete in-range ratio, and a valid block size; anything less leaves the
layout unknown, which is the answer that still recovers by scanning.

* ec: let only a genuinely absent sidecar choose the legacy layout

With no .vif the bitrot sidecar is the only record of a volume's layout, and
the mount fallback read a failed load, an unusable config, or a sidecar
stamped for another generation as "assume legacy". A uniform generation-0
volume could therefore mount with legacy or another generation's geometry and
answer reads with the wrong bytes. Present-but-unusable now fails the mount;
only actual absence keeps the legacy defaults. Shared as
EcShardConfigFromSidecar so every caller reads the sidecar the same way.

* ec: treat a recorded-but-impossible layout as corruption, not as legacy

- A .vif whose ecShardConfig is PRESENT but records an impossible ratio was
  answered with the default 10+4 and the legacy block layout, in both
  languages. That reads a uniform volume's shards at the wrong offsets and
  returns the wrong bytes. Only an entirely absent config still means "this
  predates the record"; a present one that cannot be true fails the mount.
- The shard-count bound summed two uint32 counts as int, which wraps on a
  32-bit build: 0x7fffffff + 0x7fffffff lands at -2 and slips under
  MaxShardCount. ValidEcShardCounts sums in uint64, and every EC call site
  that checked a recorded ratio now goes through it.

* ec: rebuild on the geometry the sidecar records, and flag it when it disagrees

The rebuild RPC passes BackgroundECContext, so RebuildEcFiles resolves the
layout itself — and it resolved a missing or invalid .vif to the default 10+4
with the legacy block size. Two consequences: a 12+4 volume was reconstructed
through a 10+4 matrix, which produces wrong bytes and never regenerates
shards 14-15; and the chosen geometry then contradicted a valid uniform
sidecar, which loadRebuildSidecar reported as BitrotOff — silently skipping
the input and regenerated-shard checksum checks precisely when the volume had
already lost its metadata.

The layout now resolves from the bitrot sidecar (found across the server's
disks, not just beside the base name) before falling back to the defaults,
and a present-but-impossible ratio fails instead of being replaced. A sidecar
that contradicts the chosen geometry is BitrotInvalid, which the existing
unsafeIgnoreSidecar override still lets an operator push past.

* ec: let the Rust rebuild read metadata off a sibling disk

read_ec_shard_config searches only the location the rebuild writes into, so a
volume whose .vif or generation-0 .ecsum sits on another of the server's
disks resolved to the default 10+4 with the legacy block layout — the Rust
half of the geometry-guessing the Go rebuild just stopped doing. It then
reconstructs a custom-ratio or uniform volume through the wrong
Reed-Solomon matrix and de-striping geometry.

The rebuild now looks for the .vif in its own location and then each sibling,
falls back to the generation-0 sidecar wherever that lives, and only defaults
when neither exists anywhere. The encode-time .dat size the ecx rebuild needs
is resolved the same way.

* ec: resolve a rebuild's vif from every directory that may hold it

RebuildEcFiles probed only <data-base>.vif. The caller knows the selected
location's index directory and the sibling locations, but passed neither for
metadata: additionalDirs carried shard directories only, and were searched
for shards and the checksum sidecar. A split -dir/-dir.idx layout, or a disk
holding only shards, therefore resolved a pre-sidecar custom-ratio volume to
10+4 and reconstructed through the wrong matrix — never regenerating shards
14-15.

The caller now hands over the index and sibling directories, and the resolver
probes the vif across all of them, matching what the Rust resolver already
does for both the vif and the sidecar.

* ec: make every rebuild consumer agree on the layout it resolved

- The post-rebuild bitrot backfill re-derived the geometry from this
  directory's .vif alone and dropped the block size entirely, so a rebuild
  that resolved its layout from a sibling, the sidecar, or a uniform vif wrote
  a manifest describing a DIFFERENT layout — one later mounts reject, or that
  covers only the default shard count. The layout is resolved once now,
  through an exported ResolveRebuildECContext, and the rebuild and the
  backfill share that answer.
- The Rust rebuild collected only each location's data directory, so a
  sibling's INDEX directory — where a split -dir/-dir.idx layout keeps
  .ecx/.ecj/.vif — was never probed, and a custom-ratio volume still resolved
  to 10+4 with the legacy layout. Both directories of every location are
  carried now, deduped against the rebuild's own.
- A shard delivery can bring the checksum manifest with it, but the receive
  path only writes the file: a server that already had the volume mounted kept
  its resolved protection state (off) until a remount. The mount RPC
  re-resolves it once the shards it describes have been added.

* ec: cover the rebuild's directory search with tests

Reviewers flagged the sibling index directory twice, and the fix that
closed it had no test of its own: the assembly sat inline in the rebuild
handler, reachable only through a gRPC call against a populated store.
Lifting it into rebuildSearchDirs / select_rebuild_location makes the
rule assertable — a sibling contributes BOTH its data and its index
directory, a shared index directory is listed once, and the rebuild's own
data directory never repeats.

Writing the Rust cases surfaced that the two implementations do not agree
on where the rebuild's own index directory belongs, and both are right:
Go's resolver takes a single directory list, so that directory has to be
inside it, while Rust's takes the rebuild's data and index directories as
their own arguments and would search them twice. The tests now state
which contract each side is holding to, so neither drifts into the
other's shape.

Pure refactor otherwise; no behaviour change.

* ec: search the index directory for the layout sidecar

The Rust resolver looked for the generation-0 .ecsum in the rebuild's
data directory and the sibling list, but not in the rebuild's own index
directory — while the .vif lookup directly above it did, and Go's
findBitrotSidecar has always checked both bases. On a split -dir/-dir.idx
location that directory is where the metadata lives, and callers leave it
out of the sibling list precisely because it is passed here separately,
so nothing searched it.

With no .vif anywhere the sidecar is the only surviving record of the
layout. Missing it resolved a 12+4 uniform volume to 10+4 with the legacy
striping — the test added here fails with (10, 4, 0) against the old
code — and the rebuild then reconstructs through the wrong matrix and
writes .ecx offsets that no reader can follow.

* ec: let the rebuild see its own index directory

The Rust rebuild takes a single flat directory list — the shape Go's
RebuildEcFiles uses — so it cannot be handed the rebuild location's index
directory separately the way the layout resolvers are, and the handler
was passing the sibling list, which deliberately omits exactly that
directory. On a split -dir/-dir.idx location that is where .ecx and .vif
live, so the shard and index lookups could not see them.

Go has always carried that directory in additionalDirs; this lines the
two call sites up.

* ec: let a config-free vif fall through to the layout sidecar

A .vif that carries no ecShardConfig answers nothing about the layout, so
it is no more informative than an absent one — but both trees treated its
mere existence as the end of the search. Go went straight to the 10+4
legacy defaults without consulting the sidecar at all; Rust returned
whatever ec_shard_config_from could make of a single directory. A 12+4
uniform volume with a legacy config-free vif therefore resolved as 10+4
legacy, and every read landed at the wrong shard offset.

The sidecar lookup was also single-directory on both sides, while a split
-dir/-dir.idx layout keeps .vif and .ecsum with the INDEX. Go's
findBitrotSidecar has always taken both bases; the callers here passed
only the data base, and the Rust bitrot resolver derived its path from
the data base alone. Rust's layout resolver now takes a candidate
directory list — data, index, then any siblings — and searches all of it,
which also removes the early return that made the vif's presence
decisive.

load_vif_info_across_dirs reported `dir` even when load_vif_info had
found the vif in `dir_idx`. Nothing reads that field today, so this
changes no behaviour; it stops the next caller that resolves the rest of
the volume's metadata against the answer from being sent to a disk
holding none of it.

Absence stays legal throughout: a volume with neither record is genuinely
legacy. Present-but-unusable still fails the mount, now in the
config-free-vif branch too.

* ec: activate a delivered sidecar on every per-disk runtime

A vid mounts as one EcVolume per disk, each with its own resolved
protection state, but the post-delivery reload used the first-match
lookup and so touched exactly one of them. The siblings kept reporting no
protection until a remount — and since shard distribution deduplicates
the metadata files onto the first target disk for a node, the runtime
that got the .ecsum is not necessarily the one the lookup returns.

Iterate every runtime instead, via a new FindAllEcVolumes and its Rust
mut equivalent. Combined with each runtime now resolving its sidecar
against its index directory as well as its data directory, a server
sharing one -dir.idx across its disks activates all of them from the
single delivered copy.

The Rust volume server had no post-mount reload at all; it gets one here,
matching Go.

* ec: resolve the delivered sidecar across every EC metadata directory

Reloading every per-disk runtime, added last round, did not by itself
make the delivered manifest reachable. Startup mirroring copies
.ecx/.ecj/.vif to every shard-bearing disk so each mounts
self-contained, but deliberately not .ecsum, and a repair delivers
exactly one copy. Each runtime was resolving against its own two
directories, so every sibling of the disk that received the file kept
reporting no protection however often it reloaded.

Resolve one authoritative copy across every EC metadata directory
instead of duplicating the file. Mirroring .ecsum would have to keep
pace with a file that is rewritten as shards are repaired, and would not
help the reported case at all: the delivery happens at runtime, and
mirroring only runs at startup.

The regression test pins both halves — a reload restricted to the
volume's own directories still finds nothing, and the same reload
given the server's metadata directories turns protection on.

* ec: ask every directory before writing a TOFU baseline

After a rebuild the opportunistic backfill asks whether this volume
already has a checksum manifest, and answered from the data base alone.
A split -dir/-dir.idx layout keeps the sidecar with the index, and a
multi-disk server may keep it on a sibling, so an existing manifest read
as absent.

The consequence is worse than a missed read. On a false "no" the backfill
writes a fresh sidecar at the data base from whatever the shards say right
now — and the data base is the first candidate every resolver checks, so
that TOFU baseline shadows the real manifest rather than sitting beside
it. A shard that was silently corrupt gets blessed, and the record that
would have caught it stops being consulted.

FindBitrotSidecar exports the search the package already used internally,
so the question is asked of the data base, the index base and the sibling
disks — the same candidates the rebuild resolves its layout from.

* ec: refuse a shard block size no encoder could have produced

weed fix -ecx derived one from the raw shard extent, so a truncated or
partially copied shard wrote a .vif that NewEcVolume then permanently
refuses — the volume the tool was run to rescue could never mount again.
An extent that is not a whole number of small blocks cannot have come
from a uniform encode, so it is no longer offered as a candidate, and
nothing unvalidated reaches the .vif.

Claude-Session: https://claude.ai/code/session_011FRRoNKBiGbH58rs2AQyA7

* ec: derive the .vif's dat size and block size from one measurement

VolumeEcShardsGenerate stat'ed the .dat before the encode while
WriteEcFiles stat'ed it again to size the blocks. A write landing
between the two produced a .vif whose own two fields describe different
files. WriteEcFiles now leaves both on the context, and fills a
placeholder context in place so the caller can read them back.

Claude-Session: https://claude.ai/code/session_011FRRoNKBiGbH58rs2AQyA7

* ec: keep the source volume until every holder serves its shard layout

The uniform layout rides in a .vif field older volume servers never
knew: they discard it, mount the shards as legacy and return wrong bytes
with nothing erroring, and the shard files are the same length either
way so no other check notices. The upgrade order lived only in the
release note. VolumeEcShardsInfo now reports the block size the holder
actually serves, in both the Go and Rust servers, and the pre-delete
verification refuses to drop the source unless every reachable holder
echoes the one the shards were encoded with — while a rollback still
exists. A server that predates the field answers 0, which is the
negative answer.

* ec: drop the rebuild's dead block-size parameters

generateMissingEcFiles never reads largeBlockSize/smallBlockSize —
Reed-Solomon reconstruction is layout-agnostic — so passing the legacy
constants only advertised a layout the rebuild does not use. Also move
UniformBlockSize's doc off ValidateBlockSize.

Claude-Session: https://claude.ai/code/session_011FRRoNKBiGbH58rs2AQyA7

* ec: warn about EC defaults only when the mount used them

The "vif file not found, using defaults" warning fired even after the
bitrot sidecar supplied a non-default layout, sending anyone triaging
wrong bytes after the legacy layout the volume never mounted on.

Claude-Session: https://claude.ai/code/session_011FRRoNKBiGbH58rs2AQyA7

* ec: stat the distributed bitrot sidecar once

The strict check re-stat'ed the file immediately before the stat that
already gates inclusion, and a failed sidecar write now fails the encode
outright, so the first could only fire on a deletion between the two
lines.

Claude-Session: https://claude.ai/code/session_011FRRoNKBiGbH58rs2AQyA7

* ec: say what the reconstruct budget actually bounds

A shard's buffer stays in bufs until its interval reconstructs, which is
after the read that filled it released its permit, so the semaphore
bounds round trips in flight and not retained bytes. Peak memory is the
intervals reconstructing at once times the shards each reaches times the
interval size.

Claude-Session: https://claude.ai/code/session_011FRRoNKBiGbH58rs2AQyA7

* test: let the fake volume server report its delivered EC layout

The pre-delete verification now asks each holder which shard block
layout it serves, and a fake that always answered "unset" looked exactly
like a volume server too old to know the field. Distribution ships the
.vif to every holder alongside its shards, so read the layout back out
of it as a real holder does.

Chris LuandLisandro Pin fcc2ea61d3 ec: scrub a volume through its parity data (#11006)
* Introduce a new `READS` scrub mode.

`READS` performs a full volume scrub but, unlike `FULL`, it will attempt to
reconstruct data for missing/damaged shard intervals from other shards in the cluster
when necessary.

The goal of this check is to ensure that EC volume contents _are readable by Seaweed_
even on a degraded storage state, by exercising parity data which is not read in `FULL`
mode. This is useful not only to validate data is user-readable, but also to detect potential
parity shard issues which may be difficult to pinpoint otherwise - particularly for older
volumes lacking sidecar data, and hence unaffected by `CHECKSUM` scrubs.

For regular volumes, this operation is equivalent to `FULL`.

Example:

```
> ec.shard.unmount --volumeId=1 --shardId=0,3,11 --delete --apply
Live shard topology for volume ID 1 (14 shards):
	0@10.200.18.89:9001
	1@10.200.18.89:9002
	2@10.200.18.89:9003
	3@10.200.18.89:9004
	4@10.200.18.89:9005
	5@10.200.18.89:9006
	6@10.200.18.89:9007
	7@10.200.18.89:9008
	8@10.200.18.89:9009
	9@10.200.18.89:9013
	10@10.200.18.89:9010
	11@10.200.18.89:9011
	12@10.200.18.89:9012
	13@10.200.18.89:9020

Will unmount + delete 3 shard(s):
	0@10.200.18.89:9001
	3@10.200.18.89:9004
	11@10.200.18.89:9011

```

* ec: report the shards a READS scrub had to rebuild

A READS scrub that recovers an interval was recording nothing, so a volume
missing three shards came back clean and nobody repaired it. The unreadable
shard is now recorded before the rebuild is attempted: READS reports the same
broken shards as FULL and differs only in whether the needles themselves
failed, which is the signal worth having - shards are gone, data is still
there.

forceDeletedNeedlesCheck now applies to READS as well, in the shell and in the
RPC guard: it runs the same needle walk as FULL.

Regenerated the proto instead of hand-editing it, so the pancis typo (which
protoc-gen-go-grpc emits into eight other files here) and the header whitespace
stay as generated.

Mirrors into the Rust volume server, which also now honors
force_deleted_needles_check rather than hardcoding it off.

Claude-Session: https://claude.ai/code/session_014yMNebkUjSbx9sfUCWJJtq

* ec: answer a deleted needle from a READS rebuild as deleted

#11020 gave the Rust recovery a deleted flag alongside its bytes, and it
answers a deleted needle with no bytes at all. The READS scrub appended that
empty answer, which does not compile against the new signature and, once it
did, would leave the needle short and report the size mismatch as damage.

Zero-fill the interval instead, the way the direct read beside it already
does: the assembled needle then reaches read_bytes as the delete-state
mismatch the walk already tolerates. Go takes the same branch off the flag
its recovery returns, rather than discarding it.

Chris Lu ae2cc8225e rust volume: mirror the VolumeConsolidateIndex RPC from Go (#10752)
The Go volume server has VolumeConsolidateIndex, which moves a volume's
.idx out of the data directory into the configured -dir.idx directory
(where an EC decode/reconstruct can leave it co-located) and reloads the
volume in place. The Rust port's proto omitted the RPC entirely, so its
generated VolumeServer trait was one method short of Go's.

Add the proto message and rpc, the gated grpc handler, and
Store::consolidate_volume_index / Volume::relocate_index_to, mirroring
Go's Store.ConsolidateVolumeIndex and Volume.RelocateIndexTo -- including
the cross-device copy fallback and the reopen-against-the-old-dir path
when the move fails.

Integration tests cover the real move (index relocated, volume still
serves reads and the move is idempotent), the no-op paths (index already
in place, no separate idx dir) and the not-found error, plus the grpc
handler end to end.

Chris Lu 567052bfb6 s3: take bucket sizes from the master's summary (#10664)
* pb: ask the master what each collection holds

Callers tracking usage were sent every volume in the cluster to add up
themselves, which is the master's largest single allocation.

* topology: summarise what each collection holds

One pass over the topology, allocating per collection rather than per volume.
Regular volumes count once each for logical totals and once per replica for
physical, taken from the lookup index, which is already keyed by volume and so
needs no set of seen ids. Ec shards are node-local so their sizes sum, while
the file and delete counts describe the volume and resolve once every holder
has been seen.

Replicas of one volume disagree while a write is landing or a heartbeat is
late. Walking a full listing took whichever replica the map iteration reached
first, so the answer moved between runs; this takes the largest, which is
stable and never reports usage below what some replica already holds.

* s3: take bucket sizes from the master's summary

The bucket size metrics pulled the whole volume list once a minute and added it
up, which cost the master 184.6MB of allocation and 17.8MB on the wire for six
numbers per collection.

  VolumeList over 550k volumes   184.6 MB allocated, 17.8 MB on the wire
  CollectionStatistics              176 bytes allocated, 47 bytes on the wire

The aggregation moves to the master with it, so the cases the removed tests
covered are now asserted against it directly.

* topology: count the replica holding the most live data

Quotas are enforced on size less deletions, and the replica with the biggest
raw size can be the one that has deleted the most. Counting it reported a
bucket smaller than it is and would leave one writable over its quota, which is
the opposite of what picking the largest was meant to guarantee.

* topology: cap a volume's deletions at what it holds

Live usage is read as a collection's size less its deletions, so a volume
reporting more deleted bytes than it has cancels live bytes belonging to other
volumes in the same bucket and reports it smaller than it is. Replica selection
already floored that volume's own live size at zero; the totals have to agree
with it.

Chris Lu ce7d388639 heartbeat: send only the volumes that changed (#10640)
* pb: let a heartbeat carry only the volumes that changed

A partial list cannot travel in volumes: a master that did not understand it
would read the absences as deletions. So changes get their own field, used only
once the master has said it compares digests and can tell when it has fallen
behind.

* master: apply the volumes a heartbeat reports as changed

Only the named volumes are touched. A full report says the server holds exactly
these; a changed report says nothing about the ones it leaves out, so absence
must not read as removal.

Also advertises that the master compares digests, which is what lets a server
stop sending its whole list. Advertising it once per connection means a server
reconnecting to a master that does not is back to full lists straight away.

* volume: send only the volumes that changed once the master accepts them

The whole list goes on every heartbeat until the master says it compares
digests, and again whenever it asks, so a master that cannot tell when it has
fallen behind never has to.

has_no_volumes stays derived from a full list alone. Deriving it from what a
heartbeat happens to carry would make a quiet one read as a server that had
lost every volume, and the master would drop them all.

The digest still covers every volume held rather than the ones sent, which is
what lets the master confirm that applying the changes left it current.

Reporting state is per-connection: a server that reconnects, or reaches a
different master, starts again from the full list.

* volume: let the zero reporting state stand for having told no master anything

A Store built as a literal, which tests do, left the reporting state nil and
panicked on the first heartbeat. As a value its zero form already means nothing
has been reported to anyone, which is exactly the state that sends the whole
list.

* rust: send only the volumes that changed once the master accepts them

Mirrors the Go volume server, with one hazard the Go side does not have: mount
and unmount deltas here are derived by diffing successive heartbeats, so a
heartbeat that carries a partial list would report every volume it left out as
unmounted. Collecting now returns the full set alongside the message, and every
site that diffs uses that rather than what went on the wire.

* volume: do not let a full-list request be lost to the heartbeat it raced

The request arrived while a heartbeat was already being built as a delta, and
committing that heartbeat cleared it, so the master waited for another digest
mismatch before asking again. Count the requests and clear only the one the
heartbeat answered.

* rust: stop marking volumes reported by a heartbeat that is thrown away

The state-notify path collected a heartbeat only to diff its volume list, then
sent a delta message of its own and dropped the one it had collected. Once
collecting recorded what the master had been told, every mount or unmount
silently marked the changed volumes as sent, and the master learned of them
only after a digest mismatch.

Snapshotting no longer records anything, and no longer expires ec volumes
whose deletion that path was already discarding.

* master: announce only the volumes a change actually brought

Every changed volume was broadcast as a new location. Volumes grow constantly
and growth moves no location, so on a busy cluster that told every connected
client about volumes it could already reach, filling bounded broadcast queues
and pushing out the topology updates that matter.

* master: ask for the full list when only one can repair the master

Delta heartbeats stop the full report, and with it the only thing that
re-registers a volume the lookup index lost. The volume server cannot see that
divergence and its digest cannot show it, so the master now checks its own two
indexes agree and asks for the list when they do not.

A node reporting one volume id twice is kept on full lists for the same reason
rather than merely skipped: its digest can never be verified, so nothing else
would tell the master what it had stopped holding.

* master: keep the volume options on every heartbeat response

A volume server takes them from whatever response arrives, and preallocate is a
bare bool with no way to tell off from unmentioned. A response sent to ask for
the volume list therefore turned preallocation off until the server reconnected.

Responses sent mid-stream now start from the configured options rather than
being built field by field.

* master: announce a volume the lookup index had lost

Repairing the index makes the volume servable again, but clients were told it
went when the node dropped out and nothing told them otherwise: the disk map
still held it, so it did not count as an arrival.

Reaching the lookup index is what makes a volume servable, so recovering an
entry there is an arrival as far as clients are concerned, on both the full
report and the changed-volume path.

Chris Lu 6d08b08f37 heartbeat: carry a volume digest and verify it (#10627)
* pb: carry a volume digest on the heartbeat

The full volume list is the only way a master notices a volume that vanished
without a delta, so it cannot simply be dropped. A digest gives the same
guarantee without the list, and a way back to the list when they disagree.

The digest has explicit presence: a server holding no volumes reports 0, which
has to stay distinguishable from a server that does not compute one at all.

* volume: report a digest of the volumes each heartbeat carries

Digests exactly what goes on the wire: volumes skipped as quarantined, phantom
or expired are absent from both the list and the digest, so the master compares
against the same set the server meant to report.

Runs the master's own hash over the master's own conversion of the message, so
the two ends cannot drift into disagreeing about a field.

* master: check the reported volume digest and ask for the list on a mismatch

Compared after everything the heartbeat carried has been applied, so agreement
means the master is current rather than that nothing changed.

Servers reporting no digest are untouched, and a mismatch on a heartbeat that
already carried the full list is reported rather than answered: there is
nothing further to ask for, so asking again would loop. Nodes reporting one
volume id twice are skipped for the same reason.

* rust: report the heartbeat volume digest

Mirrors the Go volume server. The master compares this against a digest it
computes itself, so the hash has to agree byte for byte across the two
implementations, not merely be a hash of the same fields: report_hash_vectors
pins it against values generated by the Go side, and the ttl and replica
placement narrowing the master applies when it decodes a message is applied
here too rather than assumed away.

A drift there would not corrupt anything, but every volume server on this
implementation would report a digest the master can never match and fall back
to sending its whole volume list forever, which is the cost the digest exists
to avoid.

* master: pin what the digest check does to each kind of report

The upgrade story rests on these: a server that reports no digest is never
asked for anything, so the two sides can be upgraded in either order, and a
disagreement that resending cannot fix is reported rather than re-asked, so it
cannot loop.

* topology: enumerate the digest coverage test from the message

The list of fields was written out by hand, so a field added to
VolumeInformationMessage later would fall outside the digest while the test
went on passing, and a change to it would never reach the master. Walk the
message descriptor instead.

Some fields are narrowed or normalised on the way into VolumeInfo, so the
smallest change to the wire value can land back on the stored one; the test
offers several values per field and asks only that some change is visible.

Chris Lu 9c37e52c9b volume: EC decode onto a clean peer via staged-new-volume adopt (Go+Rust) (#10463)
Decoding EC shards back to a normal volume in place reconstructs <vid>.dat
in the shards' own directory, so the vid is momentarily registered as both
an EC and a normal volume in one location — the load/scan path then sees it
as both, risking mount ambiguity and needle loss. VolumeEcShardsToVolume
still supports that in-place path; this adds the primitives to decode onto
a *clean* peer instead:

  - ReceiveFile gains a staged-new-volume mode: when the volume does not
    exist here and ReceiveFileInfo.disk_type is set, pick a free-slot disk
    of that medium and write <base><ext>.copying (not a valid volume name,
    so the scanner never half-loads a partial push).
  - VolumeEcShardsToVolume gains from_staged: adopt the pushed .dat/.idx/
    .vif — rename .copying into place under a .note in-progress marker,
    then mount — so <vid> lands on the peer only as a normal volume.

The caller decodes the shards off-box and streams the finished volume to a
peer holding no shard of the vid on the target medium. Go and Rust volume
servers get identical handlers. Proto: ReceiveFileInfo.disk_type (12; 8-11
reserved for versioned-EC), VolumeEcShardsToVolumeRequest.from_staged (3) +
disk_type (4).

The service url was always derived as <account>.blob.core.windows.net,

Name the blob service url instead and those accounts become reachable.
The url has to be https, since the account key or the bearer token would
otherwise travel in the clear.

A url like https://:443/ has a host of ":443", so the emptiness check on
Host let it through and the request only failed once it reached Azure.
The hostname is what has to be there.

Chris Lu 3ae4e9c563 azure: authenticate with Entra ID instead of a storage account key (#10456)
* azure: authenticate the blob sink with Entra ID

Shared account keys have to be distributed and rotated everywhere a sink
runs. Leaving account_key empty now falls back to the identity chain, so a
workload identity or managed identity carries the authorization instead.

* azure: authenticate remote storage with Entra ID

The remote storage client demanded an account key and refused to start
without one. Fall back to the identity chain when it is absent, and let
azure.client_id pin a user-assigned identity.

* azure: reject a malformed storage account name

The account name is interpolated into the service URL, so a name carrying
a "/", "?" or "@" moves the authority elsewhere and an authenticated
request follows it. Hold callers to Azure's own naming rule instead.

* azure: keep a leftover environment key off the identity path

A configured client id asks for Entra ID, but AZURE_STORAGE_ACCESS_KEY
still filled in the account key behind it. An old mounted secret would go
on authenticating until it rotated, and the failure then blamed the key.

* azure: say what the identity path reads from the environment

A pinned client id alone is not enough for workload identity: the tenant
and the projected token come from the environment, and missing them only
surfaces later, when a token is first requested.

Chris Lu 564803becd shell: show who holds the cluster lock (#10353)
* regenerate master_grpc.pb.go with protoc-gen-go-grpc v1.6.2

The other generated pb files are already on v1.6.2; this one was stale.

* shell: keep unlock from racing the lease renewal

A renewal RPC in flight while ReleaseLock runs re-creates the lock on the
master after the release deletes it, and can blank the client name if the
renewal reads it mid-release. The stale-token release is then ignored, so
the lock stays held (sometimes anonymously) until it expires. Serialize
the renew and release RPCs, and set the client name before flipping
isLocked so the renewal never sends a partial acquisition.

* shell: restart lease renewal after a failed renewal

The renewal goroutine exits on error but never cleared its running flag,
so later locks in the same process were never renewed and silently
expired after ten seconds.

* shell: show who holds the cluster lock

A blocked lock command gave no hint that another client holds the lock
(the refusals only surfaced at -v=2), and cluster.status reported the
shell's own lock state as if it were the cluster's. Add a
GetAdminLockStatus RPC to the master so lock prints the holder before
blocking and cluster.status shows the actual cluster-wide holder. Both
degrade silently against masters without the RPC.

* shell: bound admin lock RPC attempts with timeouts

The lease, renew, release, and holder-status calls all ran without a
deadline, so an unresponsive master could hang the renewal goroutine,
an unlock (which now waits on the renewal mutex), or the shell prompt.
Give each attempt its own short context; the retry loops still resolve
a fresh leader on the next try.

* master: reject admin token release on non-leaders

A follower holds no lock state, so it answered a release with success
while the leader kept the lock until expiry. Refuse like LeaseAdminToken
does so the client can try the leader instead.

* shell: leave the lock release call unbounded

A release cut short by a deadline leaves the lock held on the master
until it expires, so a slow master would turn every unlock into a
ten-second ghost lock. Restore the single fire-and-forget attempt;
the timeouts stay on the lease and renew paths, where a stalled call
forfeits the lease anyway.

* shell: release only the token unlock started with

A RequestLock racing a slow release (the admin presence lock does this
on shutdown) could have its freshly acquired token sent in the release
request or zeroed by the trailing stores. Capture the token once under
the mutex and compare on clear so a concurrent acquisition survives an
in-flight unlock.

FULL EC scrubs can opt into strict deleted-needle verification via the
-forceDeletedNeedlesCheck shell flag, off by default since it can report
false positives when EC indexes disagree. Rejected for non-FULL modes.

The Rust volume server parses the new field and ignores it: its FULL
scrub verifies shards via RS parity, not per-needle reads.

* volume: require admin auth for ScrubEcVolume

ScrubEcVolume ran unauthenticated while its sibling ScrubVolume, and the
rest of the mutating volume handlers, gate on checkGrpcAdminAuth. Close
the gap so an EC scrub can't be triggered anonymously.

Fail in the client before fanning out to every volume server, instead of
erroring halfway through once the servers reject the request.

.ecsum sidecar payload is wire-identical across the Go and Rust binaries:
EcBitrotProtection / EcShardChecksums / ChecksumAlgorithm, VolumeScrubMode.CHECKSUM=4,
and VolumeEcShardsCopyRequest.copy_ecsum_file. No code uses them yet — the .ecsum
format, producer, mount-load, copy, and scrub land in following commits.

* feat(ec): port the .ecsum bitrot checksum module

ec_bitrot.rs mirrors weed/storage/erasure_coding/ec_bitrot.go: the .ecsum sidecar
format (14-byte big-endian ECSU header + CRC32C over a prost-serialized
EcBitrotProtection payload), the per-shard per-block CRC32C producer
(ShardChecksumBuilder), save/load with payload self-integrity, manifest
validation, status resolution, and verify_shard_file_blocks for the CHECKSUM
scrub. A byte-exact test pins the serialized bytes against the Go reference's
identical constant so a format drift in either binary fails loudly.

Producer wiring (encode/vacuum), mount-load, copy, and the mode-4 dispatch land
in following commits.

Deterministic EcBitrotProtection -> exact on-disk bytes, asserted against a

.ecsum from a Rust-written one.

Claude-Session: https://claude.ai/code/session_015EE9Sc9EvNp8BCVva4RKdo

* feat(ec): write the .ecsum bitrot sidecar during EC encode

write_ec_files now feeds each shard's bytes through a per-shard
ShardChecksumBuilder as it writes them, then persists the generation-0 sidecar

SaveBitrotSidecar. Best-effort: a failed sidecar write leaves the generation
unprotected rather than failing the encode. A test confirms the produced sidecar
validates and its per-block CRCs match every on-disk shard.

* feat(ec): load the .ecsum at mount + EcVolume::checksum_scrub

EcVolume now loads and validates its generation-0 .ecsum sidecar at mount,
caching the parsed protection + BitrotStatus (Off/On/Invalid), and exposes
bitrot_protection() mirroring Go's EcVolume.BitrotProtection(). checksum_scrub()
verifies every locally-held shard's raw bytes against the sidecar block CRCs —
the only path that exercises cold parity shards — reporting mismatched shards
without mutating anything; a wholesale mismatch beyond parity is flagged as a
suspect sidecar rather than mass shard corruption. Mirrors Go's ChecksumScrub.

Claude-Session: https://claude.ai/code/session_015EE9Sc9EvNp8BCVva4RKdo

* feat(scrub): dispatch EC CHECKSUM (mode 4) to checksum_scrub

Accept VolumeScrubMode.CHECKSUM=4 and route it to EcVolume::checksum_scrub,
accumulating blocks scanned + mismatched shards into the scrub response, plus the
CHECKSUM scrub-mode metric label. Read-only bitrot verification over local shards.

Claude-Session: https://claude.ai/code/session_015EE9Sc9EvNp8BCVva4RKdo

* feat(ec): copy the .ecsum sidecar during VolumeEcShardsCopy

Honor copy_ecsum_file: when set, copy the generation-0 .ecsum alongside the
shards so protection travels with them, mirroring Go's non-2PC copy path.
Tolerant of a missing source (empty stream) — the 0-byte file is dropped so
mount sees no sidecar (protection off) rather than a truncated/invalid one.

Claude-Session: https://claude.ai/code/session_015EE9Sc9EvNp8BCVva4RKdo

* feat(ec): remove the .ecsum sidecars when destroying an EC volume

remove_ec_volume_files now clears <base>.ecsum (and any versioned .ecsum.v<N>)
from the data and idx dirs, so a vid reuse can't load a stale sidecar. Mirrors
Go's removeBitrotSidecars.

Claude-Session: https://claude.ai/code/session_015EE9Sc9EvNp8BCVva4RKdo

* style(ec): align bitrot comments and test setup for merge-cleanliness

Match the shared bitrot code (write_ec_files, encode_one_batch, checksum_scrub,
the encode sidecar test) to the canonical wording/layout so the volume-server
Rust port stays line-aligned across trees, keeping periodic merges conflict-free.
No behavior change.

Chris Lu 77bf2a3ab0 volume.balance: gate on real physical disk usage (fixes #10160) (#10162)
* shell: add volume.balance -byDiskUsage to balance by actual data

The default balancer ranks servers by slot density, dividing used volumes by
MaxVolumeCount. When MaxVolumeCount is configured higher than the disk can hold,
a physically near-full server looks nearly empty and gets picked as the move
target, so balancing drains less-full servers onto an already-full one.

-byDiskUsage ranks servers by the actual data they hold (sum of volume sizes)
instead, so the fullest-by-data server is treated as full and balancing drains
it. It assumes comparable disk sizes per disk type and still respects each
server's free volume slots. Default behavior is unchanged.

* plumb physical disk usage into topology, gate volume.balance on it

Volume servers now report each disk's filesystem total/free bytes in the
heartbeat, and the master stores them in DiskInfo. volume.balance uses them to
skip any move target whose disk is already near full (-maxDiskUsagePercent,
default 90), so an over-configured maxVolumeCount can no longer make a
physically full server look empty and get drained onto. The gate judges each
server against its own disk, so heterogeneous disk sizes are fine; servers that
do not report bytes fall back to slot-only behavior.

Rust seaweed-volume mirrors the heartbeat reporting.

* admin: report real physical disk capacity when volume servers provide it

The dashboard estimated server capacity as maxVolumeCount * volumeSizeLimit,
which overstates it when maxVolumeCount is set higher than the disk holds.
Prefer the filesystem capacity now reported per disk, falling back to the
estimate for servers that do not report it.

* worker: gate automatic balance on physical disk fullness too

The maintenance balance worker selects the least slot-utilized server as the
move destination, so an over-configured maxVolumeCount makes a physically full
server look empty and get drained onto — the same defect as the shell command.
Now that DiskInfo carries real disk bytes, skip any destination whose disk is
at/above 90% used (per server, against its own disk); a full server can still be
a source. When every candidate destination is full, create no tasks. Servers
that do not report disk bytes are not gated.

* balance: share the physical-disk-fullness gate between shell and worker

The shell volume.balance command and the maintenance balance worker each grew
their own copy of the disk-fullness gate (targetDiskTooFull / destinationDiskTooFull)
and a maxDiskUsagePercent=90 constant. Pull both into weed/topology/balancer
(DiskTooFullAfter + DefaultMaxDiskUsagePercent) so the policy has one home and the
two balancers can't drift.

* balance: harden the physical-disk gate

Guard against a nil DiskInfo in the byte/slot lookups. Let a zero disk-capacity
report clear previously stored bytes (0 means "not reported" for bytes, unlike
maxVolumeCount), so a server that stops reporting falls back to slot-only instead
of trusting stale capacity. In the worker, charge each planned move's bytes to
its destination within a detection cycle so the gate sees a target fill up rather
than only its heartbeat-time free space. Note the per-location capacity summing
assumes one location per filesystem (the used ratio the gate relies on stays
correct regardless; absolute capacity can over-report).

Chris Lu 41d6c821ba feat(topology): report empty disks (per-disk type + capacity in heartbeat) (#10166)
* fix(topology): keep physical disk 0 distinct in SplitByPhysicalDisk

DiskId 0 doubles as the first physical disk (Locations[0]) and the
protobuf "unset" default. SplitByPhysicalDisk folded every DiskId-0
record onto the aggregate DiskId whenever that was non-zero, so on a
multi-disk node the first disk's volumes merged into whichever disk
held volumes[0]: the node reported one fewer disk, the sibling showed
~2x volumes, and per-disk max was smeared across the survivors. This
surfaced as cluster.status and volume.list undercounting disks.

Only treat 0 as unset when no record carries a non-zero DiskId; with a
mix, 0 is a real disk and keeps its own entry.

* fix(admin): resolve physical disk 0 in active-topology indexes

rebuildIndexes re-derived each volume/EC record's physical disk id with
the same "DiskId 0 means unset" heuristic SplitByPhysicalDisk used, so
the two agreed only by sharing the bug. Now that SplitByPhysicalDisk
keeps disk 0 distinct, the duplicated heuristic would fold disk-0 records
onto a sibling while at.disks kept them on disk 0; GetVolumeLocations and
GetECShardLocations then matched no record and silently dropped every
volume and EC shard on the first disk, starving balance and EC tasks.

Build the indexes from the same SplitByPhysicalDisk reconstruction that
builds at.disks, so the keys always resolve. One source of truth instead
of a parallel normalize.

* fix(ec): allow physical disk 0 as preferred EC shard target

pickBestDiskOnNode gated its result on bestDiskId != 0, but 0 is both a
valid physical disk and the uint32 zero value, so a best-scoring disk 0
was discarded and the non-matching fallback returned instead. Gate on
bestScore.

* test(admin): cover EC-shard index resolution for physical disk 0

rebuildIndexes builds ecShardIndex the same way as volumeIndex; pin the EC
path too so a shard on disk 0 keeps resolving via GetECShardLocations.

* proto: per-disk type/capacity in DiskTag, DiskInfo.physical_disks

DiskTag gains type + max_volume_count so the heartbeat can describe every
physical disk, including ones holding no volumes or EC shards. DiskInfo
gains physical_disks so the master can hand the full per-type disk set to
per-physical-disk consumers.

* feat(volume): report each physical disk's type and capacity

CollectHeartbeat fills DiskTag.type and the per-disk effective max for
every location, so the master can account for disks that hold no volumes
or EC shards yet. Rust heartbeat mirrors it.

* feat(master): surface empty disks in the per-physical-disk view

The master records each disk's type and max from DiskTags and lists them
on DiskInfo.physical_disks per type, including disks with no volumes or
EC shards. SplitByPhysicalDisk enumerates that full set and gives each
disk its exact max, so cluster.status, volume.list and the admin
topology count and can target empty disks. Without physical_disks the
even-split fallback is unchanged.

* fix(master): clamp per-disk free at zero for over-allocated disks

In the exact-max path FreeVolumeCount could go negative when a disk holds
more volumes than its max; a negative would reduce the node's summed free
and block placement on healthy disks. Clamp at 0.

* fix(master): rebuild disk tags fresh each heartbeat

DiskTags is the full authoritative per-disk list every heartbeat, so
rebuild dn.diskTags from scratch like dn.diskBackends; merging left stale
entries for removed disks.

* fix(master): keep zero-capacity disks in physical_disks

A disk reporting max 0 (an unavailable disk) is a valid physical disk,
not a signal to drop it. List every disk of the type, but only emit
physical_disks when the node reports real per-disk capacity, so an older
server sending all zeros still falls back to the aggregate split.

* test(volume): cover disk-space-low per-disk max in heartbeat

Assert DiskTag.max_volume_count follows the used-slots override when a
location is low on space, matching the per-type max_volume_counts.

* chore: trim comments on the empty-disk change

Drop narration; keep only the non-obvious why (disk-0 sentinel, exact-max
free clamp, EC slots not subtracted, all-zeros fallback).

* refactor(master): merge per-disk tags and capacity into one map

diskTags and diskBackends were parallel maps keyed by the same DiskId and
filled together from DiskTags. Fold them into one diskMetas map of
{tags, type, max}.

* refactor(proto): per-disk max as a map keyed by disk id

physical_disks was a repeated {disk_id, max_volume_count} whose fields
duplicated DiskInfo's own disk_id/max_volume_count. A map<uint32,int64>
keyed by disk id expresses "max per disk" directly, drops the extra
PhysicalDiskInfo message, and the consumer reads it as the disk set.

* docs(proto): note DiskInfo.disk_id's two meanings

Identity on a per-physical-disk DiskInfo (from SplitByPhysicalDisk),
representative fallback on the type-keyed aggregate.

Chris Lu 2efc0e1656 ec: recover EC shards whose .ecx index lives only on a peer server (#10108)
* ec: recover EC shards whose .ecx index lives only on a peer server

A volume server that boots with EC shard files on disk but no .ecx index
on any local disk cannot mount the shards, so the master never learns
about them. ec.rebuild works off master-registered shards, so it sees the
volume as short and gives up even though the shard data is intact.

Add an operator-triggered recovery: VolumeEcShardsMount gains a
recover_missing_index flag that makes the volume server fetch the missing
.ecx (plus .ecj/.vif) from a peer holding it and mount the on-disk shards.
ec.rebuild runs this across the cluster before planning, so orphaned
shards register and the rebuild sees the true shard set.

.ecx is an immutable encode-time index, identical on every holder. .ecj
is a per-holder deletion journal that differs across holders, so the
recovered node adopts the source peer's deletion view, like a balanced or
rebuilt shard does.

* ec: mirror missing-index recovery into the Rust volume server

Port the #10104 recovery to seaweed-volume so the Rust volume server
self-heals the same layout: EC shards on disk with the .ecx index only on
a peer. Adds collect_ec_volumes_missing_index / mount_recovered_ec_shards
to the store, recover_missing_ec_indexes (master LookupEcVolume + peer
CopyFile fetch + mount) to the server, and the recover_missing_index flag
on VolumeEcShardsMount.

.ecx is the immutable encode-time index, identical on every holder. .ecj
is a per-holder deletion journal, so the recovered node adopts the source
peer's deletion view, matching the Go path.

Chris Lu 284796c7b6 fix(ec): fence stale-worker EC shard cleanup by encode generation (#9953)
* feat(ec): add encode_ts_ns to the EC task params, shard-unmount, and shard-delete RPCs

The generation fence for stale EC-worker cleanup needs the encode
generation on three messages: ErasureCodingTaskParams (admin issues it),
VolumeEcShardsUnmountRequest, and VolumeEcShardsDeleteRequest (the worker
carries it to the volume server). Additive fields only; 0 preserves the
existing unfenced behavior. Mirror the two volume-server fields in the
Rust volume server's proto copy.

* feat(ec): issue the EC encode generation from the admin and carry it on the worker

Stamp each EC proposal's encode_ts_ns from the admin's per-cycle
DetectionSequence (a single-clock value) so generations are globally
ordered even though detection runs on a rotating worker. The worker
writes that generation into the distributed .vif and passes it on its
shard unmount/delete RPCs; it falls back to a local timestamp for the
.vif only on the unfenced legacy/shell path (keeping the read guard on).

* fix(ec): fence the stale-worker EC shard unmount and teardown by generation

A reaped-but-still-running EC worker's cleanupStaleEcShards issued a
generation-blind unmount + full teardown that could unmount and then
overwrite a newer run's live shards on a shared node. Both RPCs now
carry the encode generation: the volume server unmounts/deletes a disk
only when its .vif generation is strictly older than the request, and
preserves a same-or-newer generation, a generation-0 (recovered or
pre-upgrade) volume, and an unreadable .vif. Unload is per-disk, never
node-wide. Request generation 0 keeps the blanket teardown for the shell
pre-encode cleanup and pre-upgrade callers. Mirrored in the Rust volume
server.

* test(ec): cover the generation-fenced teardown and unmount

End-to-end volume-server tests: a fenced FullTeardown wipes a strictly-
older generation, preserves a newer one, preserves a generation-0 volume,
and blanket-wipes on request generation 0; the gen-aware unmount preserves
a same-or-newer mounted generation; and the .vif generation reader handles
present/absent/no-config cases.

* test(ec): pin the fenced .vif==teardown generation and the unreadable-.vif preserve

A fenced run must stamp the admin generation verbatim into the .vif so it
matches the generation sent on the teardown RPCs; add a regression test
that sets the task generation and asserts the .vif carries it exactly.
Also cover the present-but-unparseable .vif case (reads as generation 0,
preserved) and correct the readEcGenerationTsNs docstring accordingly.

* fix(ec): surface EC full-teardown filesystem errors in the Rust volume server

remove_ec_volume_files(_full_teardown) discarded every fs::remove_file
error, so a teardown that failed on permissions or a full disk still
returned full_teardown_done=true and left stale artifacts to collide with
the next encode. Return io::Result, ignore NotFound, propagate the first
real error, and have the teardown RPC surface it -- matching the Go
contract. The best-effort reconcile/load-cleanup callers keep ignoring it.

* refactor(ec): reuse the EC volume lookup on unmount and short-circuit the gen read

Address review: the Rust unmount fence reuses the ec_vol it already
fetched instead of a second find_ec_volume; the Go .vif generation reader
breaks out of the data/idx loop early when the two dirs are the same.

Chris Lu da243b9423 fix(ec): group orphan-source completeness by encode generation (topology encode_ts_ns) (#9952)
* feat(ec): carry the encode generation through the topology heartbeat

Add encode_ts_ns (field 14) to VolumeEcShardInformationMessage and
populate it from each EC volume's .vif identity. The volume server emits
it on the full and incremental heartbeats; the master stores it on
EcVolumeInfo and re-emits it via GetTopologyInfo, so the admin/worker
layer can see which encode run produced each shard set. Field 14 avoids
the enterprise fork's reserved 10-13. Mirror the proto field and both
heartbeat emit sites in the Rust volume server.

* fix(ec): group orphan-source shard completeness by encode generation

countExistingEcShardsForVolume ORed EcIndexBits across every disk, so two
interrupted encode runs whose shard sets overlap unioned into a
false-complete set -- triggering the orphaned-source delete while no
single generation was actually complete. Group shards by encode_ts_ns and
return the largest single generation's count, so the trigger fires only
when one run holds the full set. Shards from pre-upgrade servers
(encode_ts_ns==0) form their own bucket.

The heartbeat carries one encode_ts_ns per (volume, disk), so this
separates generations on different disks; same-disk mixing is prevented
upstream by the pre-encode artifact wipe and the cross-run read guard.

* fix(ec): guard against a nil Ec shard info entry in the generation count

Defensive: a manually-constructed or corrupted topology could carry a nil
entry in EcShardInfos. Skip it rather than dereference.

* fix(ec): carry the encode generation on the EC shard unmount delta

The mount delta sets EncodeTsNs; the unmount deletion delta left it 0.
Populate it from the Ec volume before unloading so both incremental
deltas are consistent (the Rust volume server already does this via its
snapshot diff).
2026-06-14 00:14:12 -07:00
Chris Lu 79ac279fe1 fix(ec): don't mix EC shards from different encode runs (#9880)
* feat(ec): add encode_ts_ns to EC shard metadata and the shard read RPC

EcShardConfig and VolumeEcShardReadRequest gain an int64 encode_ts_ns
(encode time in unix nanos). It rides in .vif and the read request so a
read can be scoped to the encode run that produced the index.

* fix(ec): stamp each encode and reject cross-run shard reads

Generate stamps EncodeTsNs into the volume's .vif. Reads carry it to the
shard's owning volume (resolved together via FindEcVolumeWithShard, so a
multi-disk server validates the disk that actually serves the bytes) and
reject a shard from a different encode run, recovering from parity. A
zero on either side (pre-upgrade volume) skips the guard.

* fix(ec): stamp the encode identity on the worker-generated .vif

The worker-local encode path now writes EncodeTsNs (and the resolved EC
ratio) into the .vif, so the read guard is not silently off for volumes
encoded by the maintenance worker.

* fix(ec): wipe stale EC artifacts before re-encoding

VolumeEcShardsGenerate evicts any in-memory EcVolume for the volume and
removes its on-disk shard/index/sidecar files before writing fresh ones,
so a retried encode never builds on a partial prior run and the unlink
frees the inodes instead of leaving open fds serving old bytes.

* fix(ec): unmount EC shards across all disks

UnmountEcShards walked only the first disk holding the shard, leaving a
duplicate copy mounted on a sibling disk (split-disk reconciled volumes)
still serving and heartbeating. Traverse every disk and emit one
deletion delta per disk.

* fix(ec): delete orphan shards without a local .ecx

deleteEcShardIdsForEachLocation gated shard-file removal on a local .ecx,
so it could not clean an orphan .ecNN left by a failed copy on a disk
with no index. Delete the requested shard files unconditionally; the
index-file (.ecx/.ecj/.vif) routing stays gated as before.

* fix(ec): clear stale EC shards cluster-wide before re-encoding

ec.encode unmounts and deletes EC shards for the target volumes on every
node before regenerating: fatal for the shards the topology reports
(mounted leftovers), best-effort for the rest (a sweep that catches
unmounted failed-copy orphans). A down node is a no-op.

* fix(ec): don't nil EC fds on close so reads can't race eviction

A reader resolves an EcVolume/shard under the lock then reads after it is
released, so an eviction that nils ecxFile/ecdFile would race that read
and panic. Close the fds without nilling the fields: the field is now
write-once (no data race) and a concurrent read hits a closed fd, getting
a clean error that the caller recovers from parity.

* fix(ec): wipe stale EC artifacts on every disk and surface failures

The pre-encode wipe only deleted beside the source volume, so a stale
shard on a sibling disk survived and could be mounted against the new
index at reconcile. Sweep every disk. Removal also ignored os.Remove
errors, reporting a failed cleanup as success and letting a stale shard
join the next generation; surface the first real failure (treating
already-gone as success) from removeStaleEcArtifacts and the shard delete.

* fix(ec): log when a local shard is skipped for a different encode run

The cross-run guard returned errShardNotLocal, indistinguishable in logs
from a genuinely-absent shard. Add a V(1) line naming both EncodeTsNs so
operators can tell "wrong encode generation" from "shard not here".

* fix(ec): surface metadata removal failures in the shard delete path

deleteEcShardIdsForEachLocation still dropped os.Remove errors on the
.ecx/.ecj/.vif/sidecar cleanup. A surviving stale .ecx is the orphan-index
condition this path prevents, so route those through removeFileIfExists and
return the first real failure instead of reporting cleanup as success.

* fix(ec): fail orphan cleanup when a reachable node's delete fails

The pre-encode orphan sweep swallowed every error for unreported (node,
volume) pairs. That is only safe for an unreachable node, which cannot
receive this encode's new generation. A reachable node whose delete
genuinely failed (permission/IO) keeps an orphan shard that a later copy
re-stamps with the new run's volume-level .vif identity, so the read guard
would accept stale data. Surface those; stay best-effort only for
unreachable nodes (gRPC Unavailable / no status).

* fix(ec): guard ecjFile under its lock in the EC delete path

EcVolume.Close nils ecjFile under ecjFileAccessLock; a delete that resolved
its .ecx lookup before a concurrent eviction (the generate-time
UnloadEcVolume) could then reach the journal append with a nil fd. Bail
with a clear "volume closed" error under the lock instead.

* fix(ec): reject an unstamped shard when the caller has an encode identity

The read guard required both identities nonzero, so a current (stamped)
caller accepted a holder with identity 0 and could be served a stale
pre-upgrade shard. Reject when the caller is stamped and the holder
differs (including unstamped); stay lenient only when the caller itself
has no identity (pre-upgrade reader). A skipped shard recovers from parity.

* fix(ec): full-teardown delete so cluster cleanup wipes a whole generation

The pre-encode cluster sweep deleted only the listed canonical shards on
remote nodes, leaving index/sidecar (and, on builds with versioned
generations, those too) behind. Add a full_teardown flag to
VolumeEcShardsDelete that evicts the volume and wipes every EC artifact for
it on every disk via removeStaleEcArtifacts; the shell and worker pre-encode
cleanup paths set it. Other delete callers (balance/decode/repair) are
unchanged.

* fix(ec): take ecjFileAccessLock before the nil-check in Sync and Close

Sync and Close read ev.ecjFile before acquiring ecjFileAccessLock while
Close nils it under the lock, a data race on the field. Take the lock
first, then nil-check inside, in both.

* fix(ec): acknowledge full_teardown so a pre-upgrade server can't fake success

An old volume server silently ignores full_teardown and returns success
for an ordinary delete, so the caller wrongly believes the generation was
wiped and copies a fresh gen-0 onto an unwiped node. Echo full_teardown_done
in the response; the worker destination cleanup fails when it is absent, and
the shell cluster sweep fails for a reported (mounted) leftover while staying
best-effort for an unreported node. encode_ts_ns stays an accepted transient
(an old server just skips the new read guard, no regression).

* fix(ec): fail the pre-encode sweep for any reachable node that can't ack teardown

A reachable pre-upgrade server ignores full_teardown and returns success
without wiping an orphan, which a later copy then folds into the new
generation. Treat a missing full_teardown_done ack as fatal for every
reachable node (best-effort only for a gRPC-unreachable one), not just for
topology-reported pairs.

* fix(ec): return the served shard identity and validate it client-side

The encode identity was only enforced server-side, so a pre-upgrade server
ignored the request field and served bytes unchecked. Echo the served
shard's EncodeTsNs on every read response chunk and have the client reject a
mismatch (including 0 from an old server), so the guard holds regardless of
server version; a rejected read recovers from parity.

* fix(ec): reject a short/empty remote shard read instead of serving zeros

doReadRemoteEcShardInterval accepted an immediate EOF or a short stream and
returned success with a partly zero-filled, unvalidated buffer (the server
stamps the identity only on chunks that carry bytes). A non-deleted interval
must arrive whole: require n == len(buf), exempting the is_deleted
short-circuit (n=0), matching readLocalEcShardInterval's local check. A short
read now fails so the caller recovers from parity.

* test(ec): fake volume server echoes the full_teardown acknowledgement

The worker now fails a teardown delete that isn't acknowledged (so a
pre-upgrade server can't silently skip the wipe). The fake server's no-op
VolumeEcShardsDelete returned an empty response, which the worker read as a
skipped teardown and aborted the encode. Echo full_teardown_done.

* feat(ec): mirror the encode-run identity guard + full_teardown into the Rust volume server

The Go volume server stamps an encode-run identity (encode_ts_ns) into the .vif
and rejects a read served from a shard of a different run; full_teardown wipes a
whole generation and acknowledges it. The Rust volume server had none of it.
Mirror the shared logic: load encode_ts_ns from the .vif onto the EcVolume,
stamp it on every read response, and reject a request/response mismatch on both
the server and the distributed-read client (recovering from parity); handle
full_teardown by evicting the volume and wiping every EC artifact on each disk,
echoing full_teardown_done so the caller can detect a server that ignored it.

* fix(ec): remove a stale .vif on full teardown of a shard-only node

A shard copy installs shards + .ecx before .vif, so an interrupted copy after a
teardown could mount the new files under the previous run's identity / version /
shard ratio / dat_file_size carried by the surviving .vif. Remove .vif during
full teardown, gated on .idx absence so a source-volume holder keeps its live
.vif. In Rust this lives in a teardown-only helper so the reconcile / load-
fallback paths (which share the base removal) still preserve .vif.

* fix(ec): treat a missing teardown ack as fatal, not as an unreachable node

isNodeUnreachable returned true for any non-gRPC-status error, so a reachable
pre-upgrade server's missing full_teardown_done ack (a plain error) was
classified unreachable and the unreported pair was silently skipped. Classify
only a real codes.Unavailable as unreachable, and wrap the missing ack in a
sentinel the sweep treats as fatal regardless. A genuinely down node still
surfaces as Unavailable from the RPC and stays best-effort.

* fix(ec): reject a short shard read in the local EC needle reader

read_ec_shard_needle ignored the byte count from shard.read_at and appended the
whole pre-sized buffer, so a truncated shard's zero-filled tail passed the later
length check and parsed as garbage. Require n == buf.len() per interval, erroring
on a short read like the local interval reader already does.

* fix(ec): probe reachability before skipping a node that returns Unavailable

The pre-encode sweep skipped any node whose teardown delete returned
codes.Unavailable, but a reachable volume server in maintenance mode also
returns that code for the maintenance-gated delete, so its stale EC files were
left behind on a node that can still receive the new generation. Confirm with a
non-maintenance-gated empty-target Ping: skip only when the node fails the probe
too (genuinely unreachable).

* fix(ec): use try_exists for the teardown .vif .idx guard

The teardown-only .vif removal gated on Path::exists(), which returns false on a
permission/IO stat error, so a stat failure on a present .idx would read as a
shard-only node and delete the live source volume's .vif. Gate on
try_exists() == Ok(false) instead, preserving the sidecar on any stat error.

* fix(ec): only skip a sweep node when a Ping confirms it is transport-down

The pre-encode sweep skipped a node whenever its teardown delete and a liveness
Ping both failed, but it treated ANY Ping error as down — an application-level
Internal/ResourceExhausted, or Unimplemented from a pre-Ping server, left a
reachable node's stale generation in place. Classify the Ping tri-state and skip
only when it transport-fails with codes.Unavailable; a reachable or inconclusive
node stays fatal.

* fix(ec): exclude sweep-skipped nodes from the encode's rebalance

The pre-encode sweep skips a genuinely-down node best-effort, but the rebalance
then recollected the current topology — a node that recovered between the two
could become a copy target and receive the new generation while still holding
its stale, never-cleared shards. Have the sweep return the skipped set and
exclude those nodes from the rebalance for this encode, so a node we could not
clean cannot receive the new generation. Standalone ec.balance is unaffected.

* fix(ec): re-sweep recovered nodes before generation so they aren't stranded

A node skipped as down by the pre-encode sweep is excluded from the rebalance,
but it can recover and become the generation host — mounting all shards locally,
then being excluded from distribution. Union-only verification accepts all
shards on one node and deletes the originals: a single point of failure. Re-sweep
the skipped nodes just before generation; one whose teardown now succeeds leaves
the skipped set and rebalances normally, while a node still down stays skipped.

* fix(ec): abort the encode if a selected source is still skipped after re-sweep

The re-sweep un-skips a recovered node, but the source was selected before it and
a node can stay down through the re-sweep then recover just in time to be the
generation host — mounting all shards locally while still excluded from the
rebalance, which union-only verification accepts before deleting the originals.
Abort the encode when a selected source remains skipped after the re-sweep.

* fix(ec): batch delete returns retriable 503 when a volume became EC mid-batch

If a volume is not EC at the batch-delete classification but is encoded to EC and
its .dat deleted before the regular-volume mutation, the mutation returns an exact
"not found" that the filer chunk-GC treats as completed, dropping the delete.
Recheck EC presence under the mutation lock and return a retriable 503 with the
"try again" token so the filer requeues it onto the EC path.

* fix(ec): recheck EC state before the regular batch-delete mutation

ec.encode mounts EC shards (copied from the .dat) before deleting the originals,
so a volume can be EC while its .dat still exists. The batch delete only rechecked
EC after a NotFound, so a successful regular-volume delete in that window wrote a
tombstone to the soon-removed .dat — the delete was lost and the needle resurrected
from the pre-tombstone shards. Recheck has_ec_volume under the write lock before
delete_volume_needle and return a retriable 503 so the filer requeues onto the EC path.

* fix(volume): make the metrics push test independent of test order

test_push_metrics_once asserted the pushed body contains the request-counter
family without ever touching the counter — a CounterVec with no children emits
nothing, so the assertion only held when another test had already created a
labelset in the shared registry. Create one in the test itself.

Chris Lu 532b088262 fix(ec): preserve source disk type across EC encoding (#9423) (#9449)
* fix(ec): carry source disk type on VolumeEcShardsMount (#9423)

When EC shards land on a target whose disk type differs from the
source volume's, master heartbeats wrongly reported under the target
disk's type. Add source_disk_type to VolumeEcShardsMountRequest; the
target server applies it to the in-memory EcVolume via SetDiskType so
the mount notification and steady-state heartbeat both carry the
source's disk type. Empty value falls back to the location's disk
type (used by disk-scan reload paths).

The override is not persisted with the volume — disk type stays an
environmental property and .vif remains portable.

* fix(ec): plumb source disk type through plugin worker (#9423)

Add source_disk_type to ErasureCodingTaskParams (field 8; 7 reserved),
populate it from the metric the detector already collects, thread it
through ec_task into the MountEcShards helper, and forward it on the
VolumeEcShardsMount RPC.

* fix(ec): mirror source disk type plumbing in rust volume server (#9423)

The volume_ec_shards_mount handler now forwards source_disk_type into
mount_ec_shard → DiskLocation::mount_ec_shards. When non-empty it
overrides ec_vol.disk_type (and each mounted shard's disk_type) via
the new set_disk_type method; empty value keeps the location's disk
type, so disk-scan reload and reconcile paths are unchanged.

Also picks up two pre-existing proto drifts that 'make gen' synced
from weed/pb (LockRingUpdate in master.proto, listing_cache_ttl_seconds
in remote.proto).

* feat(ec): bias placement toward preferred disk type (#9423)

Add DiskCandidate.DiskType and PlacementRequest.PreferredDiskType.
When PreferredDiskType is non-empty, SelectDestinations partitions
suitable disks into matching/fallback tiers and runs the rack/server/
disk-diversity passes on the matching tier first; the fallback tier
is only consulted if the matching pool can't satisfy ShardsNeeded.
PlacementResult.SpilledToOtherDiskType lets callers warn on spillover.

Empty PreferredDiskType keeps the existing single-pool behavior.

* fix(ec): plumb source disk type into placement planner (#9423)

diskInfosToCandidates now copies DiskInfo.DiskType into the placement
candidate, and ecPlacementPlanner.selectDestinations forwards
metric.DiskType as PreferredDiskType so EC shards land on disks
matching the source volume's disk type when possible. A glog warning
fires when placement had to spill to other disk types.

* test(ec): integration coverage for source-disk-type plumbing (#9423)

store_ec_disk_type_test exercises Store.MountEcShards end-to-end: a
shard physically lives on an HDD location, MountEcShards is called
with sourceDiskType="ssd", and the test asserts that the in-memory
EcVolume, the mounted shard, the NewEcShardsChan notification, and
the steady-state heartbeat all report under the source's disk type.
A companion test pins the empty-source path so disk-scan reload
keeps the location's disk type.

detection_disk_type_test exercises the worker plumbing: with a
cluster of nodes carrying both HDD and SSD disks, planECDestinations
must place every shard on SSD when metric.DiskType="ssd"; with only
one SSD node and 13 HDD nodes it must still satisfy a 10+4 layout
via spillover (and log a warning).

* revert(ec): drop unrelated proto drift in seaweed-volume/proto (#9423)

make gen pulled two pre-existing OSS changes into the rust proto
tree (LockRingUpdate / by_plugin in master.proto,
listing_cache_ttl_seconds in remote.proto). Reviewers flagged it as
scope creep — none of the rust EC fix references those fields.
Restore both files to origin/master so this branch only touches
EC-related symbols.

* fix(ec placement): treat empty disk type as hdd and skip used racks on spill (#9423)

partitionByDiskType used raw string comparison, so a PreferredDiskType
of "hdd" never matched candidates whose DiskType is "" (the
HardDriveType sentinel that weed/storage/types uses). EC encoding of
an HDD source would spill onto any HDD reporting "" even when the
cluster has plenty of matching capacity. Normalize both sides
through normalizeDiskType, which lowercases and folds "" → "hdd",
mirroring types.ToDiskType without taking a dependency on it.

selectFromTier's rack-diversity pass also kept revisiting racks the
preferred tier had already used when running on the fallback tier,
which negated PreferDifferentRacks on spillover. Skip racks already
in usedRacks so fallback placements still spread onto new racks.

* fix(ec): empty-source remount must not clobber existing disk type (#9423)

mount_ec_shards_with_idx_dir runs more than once per vid (RPC mount,
disk-scan reload, orphan-shard reconcile). After an RPC sets the
source-derived disk type, any later call passing source_disk_type=""
was resetting ec_vol.disk_type back to the location's value, which
reintroduces the heartbeat drift this PR is meant to fix. Only
default to the location's disk type when the EC volume is fresh
(no shards mounted yet); otherwise leave the recorded type alone so
empty-source reloads preserve whatever the original mount RPC set.

Chris Luandgemini-code-assist[bot] 1c0e24f06a fix(balance): don't move remote-tiered volumes; don't fatal on missing .idx (#9335)
* fix(volume): don't fatal on missing .idx for remote-tiered volume

A .vif left behind without its .idx (orphaned by a crashed move, partial
copy, or hand-edit) would trip glog.Fatalf in checkIdxFile and take the
whole volume server down on boot, killing every healthy volume on it
too. For remote-tiered volumes treat it as a per-volume load error so
the server can come up and the operator can clean up the stray .vif.

Refs #9331.

* fix(balance): skip remote-tiered volumes in admin balance detection

The admin/worker balance detector had no equivalent of the shell-side
guard ("does not move volume in remote storage" in
command_volume_balance.go), so it scheduled moves on remote-tiered
volumes. The "move" copies .idx/.vif to the destination and then calls
Volume.Destroy on the source, which calls backendStorage.DeleteFile —
deleting the remote object the destination's new .vif now points at.

Populate HasRemoteCopy on the metrics emitted by both the admin
maintenance scanner and the worker's master poll, then drop those
volumes at the top of Detection.

Fixes #9331.

* fix(volume): keep remote data on volume-move-driven delete

The on-source delete after a volume move (admin/worker balance and
shell volume.move) ran Volume.Destroy with no way to opt out of the
remote-object cleanup. Volume.Destroy unconditionally calls
backendStorage.DeleteFile for remote-tiered volumes, so a successful
move would copy .idx/.vif to the destination and then nuke the cloud
object the destination's new .vif was already pointing at.

Add VolumeDeleteRequest.keep_remote_data and plumb it through
Store.DeleteVolume / DiskLocation.DeleteVolume / Volume.Destroy. The
balance task and shell volume.move set it to true; the post-tier-upload
cleanup of other replicas and the over-replication trim in
volume.fix.replication also set it to true since the remote object is
still referenced. Other real-delete callers keep the default. The
delete-before-receive path in VolumeCopy also sets it: the inbound copy
carries a .vif that may reference the same cloud object as the
existing volume.

Refs #9331.

* test(storage): in-process remote-tier integration tests

Cover the four operations the user is most likely to run against a
cloud-tiered volume — balance/move, vacuum, EC encode, EC decode — by
registering a local-disk-backed BackendStorage as the "remote" tier and
exercising the real Volume / DiskLocation / EC encoder code paths.

Locks in:
- Destroy(keepRemoteData=true) preserves the remote object (move case)
- Destroy(keepRemoteData=false) deletes it (real-delete case)
- Vacuum/compact on a remote-tier volume never deletes the remote object
- EC encode requires the local .dat (callers must download first)
- EC encode + rebuild round-trips after a tier-down

Tests run in-process and finish in under a second total — no cluster,
binary, or external storage required.

* fix(rust-volume): keep remote data on volume-move-driven delete

Mirror the Go fix in seaweed-volume: plumb keep_remote_data through
grpc volume_delete → Store.delete_volume → DiskLocation.delete_volume
→ Volume.destroy, and skip the s3-tier delete_file call when the flag
is set. The pre-receive cleanup in volume_copy passes true for the
same reason as the Go side: the inbound copy carries a .vif that may
reference the same cloud object as the existing volume.

The Rust loader already warns rather than fataling on a stray .vif
without an .idx (volume.rs load_index_inmemory / load_index_redb), so
no counterpart to the Go fatal-on-missing-idx fix is needed.

Refs #9331.

* fix(volume): preserve remote tier on IO-error eviction; fix EC test target

Two review nits:

- Store.MaybeAddVolumes' periodic cleanup pass deleted IO-errored
  volumes with keepRemoteData=false, so a transient local fault on a
  remote-tiered volume would also nuke the cloud object. Track the
  delete reason via a parallel slice and pass keepRemoteData=v.HasRemoteFile()
  for IO-error evictions; TTL-expired evictions still pass false.

- TestRemoteTier_ECEncodeDecode_AfterDownload deleted shards 0..3 but
  called them "parity" — by the klauspost/reedsolomon convention shards
  0..DataShardsCount-1 are data and DataShardsCount..TotalShardsCount-1
  are parity. Switch the loop to delete the parity range so the
  intent matches the indices.

Chris Lu c4e1885053 fix(ec): honor disk_id in ReceiveFile so EC shards respect admin placement (#9184) (#9185)
* test(volume_server): reproduce #9184 EC ReceiveFile disk-placement bug

The plugin-worker EC task sends shards via ReceiveFile, which picks
Locations[0] as the target directory regardless of the admin planner's
TargetDisk assignment. ReceiveFileInfo has no disk_id field, so there
is no wire channel to honor the plan.

Adds StartSingleVolumeClusterWithDataDirs to the integration framework
so tests can launch a volume server with N data directories. The new
repro asserts the current (buggy) behavior: sending three distinct EC
shards via ReceiveFile leaves all three files in dir[0] and the other
dirs empty. When the fix adds disk_id to ReceiveFileInfo, this
assertion must flip to verify the planned placement is respected.

* fix(ec): honor disk_id in ReceiveFile so EC shards respect admin placement

Before this change, VolumeServer.ReceiveFile for EC shards always
selected the first HDD location (Locations[0]). The plugin-worker EC
task had no way to pass the admin planner's per-shard disk
assignment — ReceiveFileInfo carried no disk_id field — so every
received EC shard piled onto a single disk per destination server.
On multi-disk servers this caused uneven load (one disk absorbing all
EC shard I/O), frequent ENOSPC retries, and a growing EC backlog
under sustained ingest (see issue #9184).

Changes:
- proto: add disk_id to ReceiveFileInfo, mirroring
  VolumeEcShardsCopyRequest.disk_id.
- worker: DistributeEcShards tracks the planner-assigned disk per
  shard; sendShardFileToDestination forwards that disk id. Metadata
  files (ecx/ecj/vif) inherit the disk of the first data shard
  targeting the same node so they land next to the shards.
- server: ReceiveFile honors disk_id when > 0 with bounds
  validation; disk_id=0 (unset) falls back to the same
  auto-selection pattern as VolumeEcShardsCopy (prefer disk that
  already has shards for this volume, then any HDD with free space,
  then any location with free space).

Tests updated:
- TestReceiveFileEcShardHonorsDiskID asserts three shards sent with
  disk_id={1,2,0} land on data dirs 1, 2, and 0 respectively.
- TestReceiveFileEcShardRejectsInvalidDiskID pins the out-of-range
  disk_id rejection path.

* fix(volume-rust): honor disk_id in ReceiveFile for EC shards

Mirror the Go-side change: when disk_id > 0 place the EC shard on the
requested disk; when unset, auto-select with the same preference order
as volume_ec_shards_copy (disk already holding shards, then any HDD,
then any disk).

* fix(volume): compare disk_id as uint32 to avoid 32-bit overflow

On 32-bit Go builds `int(fileInfo.DiskId) >= len(Locations)` can wrap a
high-bit uint32 to a negative int, bypassing the bounds check before the
index operation. Compare in the uint32 domain instead.

* test(ec): fail invalid-disk_id test on transport error

Previously a transport-level error from CloseAndRecv silently passed the
test by returning early, masking any real gRPC failure. Fail loudly so
only the structured ReceiveFileResponse rejection path counts as a pass.

* docs(test): explain why DiskId=0 auto-selects dir 0 in EC placement test

Documents the load-bearing assumption that shards are never mounted in
this test, so loc.FindEcVolume always returns false and auto-select
falls through to the first HDD. Saves future readers from re-deriving
the expected directory for the DiskId=0 case.

* fix(test): preserve baseDir/volume path for single-dir clusters

StartSingleVolumeClusterWithDataDirs started naming the data directory
volume0 even in the dataDirCount=1 case, which broke Scrub tests that
reach into baseDir/volume via CorruptDatFile / CorruptEcShardFile /
CorruptEcxFile. Keep the legacy name for single-dir clusters; only use
the indexed "volumeN" layout when multiple disks are requested.

Chris Lu 300e906330 admin: report file and delete counts for EC volumes (#9060)
* admin: report file and delete counts for EC volumes

The admin bucket size fix (#9058) left object counts at zero for
EC-encoded data because VolumeEcShardInformationMessage carried no file
count. Billing/monitoring dashboards therefore still under-report
objects once a bucket is EC-encoded.

Thread file_count and delete_count end-to-end:

- Add file_count/delete_count to VolumeEcShardInformationMessage (proto
  fields 8 and 9) and regenerate master_pb.
- Compute them lazily on volume servers by walking the .ecx index once
  per EcVolume, cache on the struct, and keep the cache in sync inside
  DeleteNeedleFromEcx (distinguishing live vs already-tombstoned
  entries so idempotent deletes do not drift the counts).
- Populate the new proto fields from EcVolume.ToVolumeEcShardInformationMessage
  and carry them through the master-side EcVolumeInfo / topology sync.
- Aggregate in admin collectCollectionStats, deduping per volume id:
  every node holding shards of an EC volume reports the same counts, so
  summing across nodes would otherwise multiply the object count by the
  number of shard holders.

Regression tests cover the initial .ecx walk, live/tombstoned delete
bookkeeping (including idempotent and missing-key cases), and the admin
dedup path for an EC volume reported by multiple nodes.

* ec: include .ecj journal in EcVolume delete count

The initial delete count only reflected .ecx tombstones, missing any
needle that was journaled in .ecj but not yet folded into .ecx — e.g.
on partial recovery. Expand initCountsLocked to take the union of
.ecx tombstones and .ecj journal entries, deduped by needle id, so:

  - an id that is both tombstoned in .ecx and listed in .ecj counts once
  - a duplicate .ecj entry counts once
  - an .ecj id with a live .ecx entry is counted as deleted (not live)
  - an .ecj id with no matching .ecx entry is still counted

Covered by TestEcVolumeFileAndDeleteCountEcjUnion.

* ec: report delete count authoritatively and tombstone once per delete

Address two issues with the previous EcVolume file/delete count work:

1. The delete count was computed lazily on first heartbeat and mixed
   in a .ecj-union fallback to "recover" partial state. That diverged
   from how regular volumes report counts (always live from the needle
   map) and had drift cases when .ecj got reconciled. Replace with an
   eager walk of .ecx at NewEcVolume time, maintained incrementally on
   every DeleteNeedleFromEcx call. Semantics now match needle_map_metric:
   FileCount is the total number of needles ever recorded in .ecx
   (live + tombstoned), DeleteCount is the tombstones — so live =
   FileCount - DeleteCount. Drop the .ecj-union logic entirely.

2. A single EC needle delete fanned out to every node holding a replica
   of the primary data shard and called DeleteNeedleFromEcx on each,
   which inflated the per-volume delete total by the replica factor.
   Rewrite doDeleteNeedleFromRemoteEcShardServers to try replicas in
   order and stop at the first success (one tombstone per delete), and
   only fall back to other shards when the primary shard has no home
   (ErrEcShardMissing sentinel), not on transient RPC errors.

Admin aggregation now folds EC counts correctly: FileCount is deduped
per volume id (every shard holder has an identical .ecx) and DeleteCount
is summed across nodes (each delete tombstones exactly one node). Live
object count = deduped FileCount - summed DeleteCount.

Tests updated to match the new semantics:
  - EC volume counts seed FileCount as total .ecx entries (live +
    tombstoned), DeleteCount as tombstones.
  - DeleteNeedleFromEcx keeps FileCount constant and increments
    DeleteCount only on live->tombstone transitions.
  - Admin dedup test uses distinct per-node delete counts (5 + 3 + 2)
    to prove they're summed, while FileCount=100 is applied once.

* ec: test fixture uses real vid; admin warns on skewed ec counts

- writeFixture now builds the .ecx/.ecj/.ec00/.vif filenames from the
  actual vid passed in, instead of hardcoding "_1". The existing tests
  all use vid=1 so behaviour is unchanged, but the helper no longer
  silently diverges from its documented parameter.
- collectCollectionStats logs a glog warning when an EC volume's summed
  delete count exceeds its deduped file count, surfacing the anomaly
  (stale heartbeat, counter drift, etc.) instead of silently dropping
  the volume from the object count.

* ec: derive file/delete counts from .ecx/.ecj file sizes

seedCountsFromEcx walked the full .ecx index at volume load, which is
wasted work: .ecx has fixed-size entries (NeedleMapEntrySize) and .ecj
has fixed-size deletion records (NeedleIdSize), so both counts are pure
file-size arithmetic.

  fileCount   = ecxFileSize / NeedleMapEntrySize
  deleteCount = ecjFileSize / NeedleIdSize

Rip out the cached counters, countsLock, seedCountsFromEcx, and the
recordDelete helper. Track ecjFileSize directly on the EcVolume struct,
seed it from Stat() at load, and bump it on every successful .ecj append
inside DeleteNeedleFromEcx under ecjFileAccessLock. Skip the .ecj write
entirely when the needle is already tombstoned so the derived delete
count stays idempotent on repeat deletes. Heartbeats now compute counts
in O(1).

Tests updated: the initial fixture pre-populates .ecj with two ids to
verify the file-size derivation end-to-end, and the delete test keeps
its idempotent-re-delete / missing-needle invariants (unchanged
externally, now enforced by the early return rather than a cache guard).

* ec: sync Rust volume server with Go file/delete count semantics

Mirror the Go-side EC file/delete count work in the Rust volume server
so mixed Go/Rust clusters report consistent bucket object counts in
the admin dashboard.

- Add file_count (8) and delete_count (9) to the Rust copy of
  VolumeEcShardInformationMessage (seaweed-volume/proto/master.proto).
- EcVolume gains ecj_file_size, seeded from the journal's metadata on
  open and bumped inside journal_delete on every successful append.
- file_and_delete_count() returns counts derived in O(1) from
  ecx_file_size / NEEDLE_MAP_ENTRY_SIZE and
  ecj_file_size / NEEDLE_ID_SIZE, matching Go's FileAndDeleteCount.
- to_volume_ec_shard_information_messages populates the new proto
  fields instead of defaulting them to zero.
- mark_needle_deleted_in_ecx now returns a DeleteOutcome enum
  (NotFound / AlreadyDeleted / Tombstoned) so journal_delete can skip
  both the .ecj append and the size bump when the needle is missing
  or already tombstoned, keeping the derived delete_count idempotent
  on repeat or no-op deletes.
- Rust's EcVolume::new no longer replays .ecj into .ecx on load. Go's
  RebuildEcxFile is only called from specific decode/rebuild gRPC
  handlers, not on volume open, and replaying on load was hiding the
  deletion journal from the new file-size-derived delete counter.
  rebuild_ecx_from_journal is kept as dead_code for future decode
  paths that may want the same replay semantics.

Also clean up the Go FileAndDeleteCount to drop unnecessary runtime
guards against zero constants — NeedleMapEntrySize and NeedleIdSize
are compile-time non-zero.

test_ec_volume_journal updated to pre-populate the .ecx with the
needles it deletes, and extended to verify that repeat and
missing-id deletes do not drift the derived counts.

* ec: document enterprise-reserved proto field range on ec shard info

Both OSS master.proto copies now note that fields 10-19 are reserved
for future upstream additions while 20+ are owned by the enterprise
fork. Enterprise already pins data_shards/parity_shards at 20/21, so
keeping OSS additions inside 8-19 avoids wire-level collisions for
mixed deployments.

* ec(rust): resolve .ecx/.ecj helpers from ecx_actual_dir

ecx_file_name() and ecj_file_name() resolved from self.dir_idx, but
new() opens the actual files from ecx_actual_dir (which may fall back
to the data dir when the idx dir does not contain the index). After a
fallback, read_deleted_needles() and rebuild_ecx_from_journal() would
read/rebuild the wrong (nonexistent) path while heartbeats reported
counts from the file actually in use — silently dropping deletes.

Point idx_base_name() at ecx_actual_dir, which is initialized to
dir_idx and only diverges after a successful fallback, so every call
site agrees with the file new() has open. The pre-fallback call in
new() (line 142) still returns the dir_idx path because
ecx_actual_dir == dir_idx at that point.

Update the destroy() sweep to build the dir_idx cleanup paths
explicitly instead of leaning on the helpers, so post-fallback stale
files in the idx dir are still removed.

* ec: reset ecj size after rebuild; rollback ecx tombstone on ecj failure

Two EC delete-count correctness fixes applied symmetrically to Go and
Rust volume servers.

1. rebuild_ecx_from_journal (Rust) now sets ecj_file_size = 0 after
   recreating the empty journal, matching the on-disk truth.
   Previously the cached size still reflected the pre-rebuild journal
   and file_and_delete_count() would keep reporting stale delete
   counts. The Go side has no equivalent bug because RebuildEcxFile
   runs in an offline helper that does not touch an EcVolume struct.

2. DeleteNeedleFromEcx / journal_delete used to tombstone the .ecx
   entry before writing the .ecj record. If the .ecj append then
   failed, the needle was permanently marked deleted but the
   heartbeat-reported delete_count never advanced (it is derived from
   .ecj file size), and a retry would see AlreadyDeleted and early-
   return, leaving the drift permanent.

   Both languages now capture the entry's file offset and original
   size bytes during the mark step, attempt the .ecj append, and on
   failure roll the .ecx tombstone back by writing the original size
   bytes at the known offset. A rollback that itself errors is
   logged (glog / tracing) but cannot re-sync the files — this is
   the same failure mode a double disk error would produce, and is
   unavoidable without a full on-disk transaction log.

Go: wrap MarkNeedleDeleted in a closure that captures the file
offset into an outer variable, then pass the offset + oldSize to the
new rollbackEcxTombstone helper on .ecj seek/write errors.

Rust: DeleteOutcome::Tombstoned now carries the size_offset and a
[u8; SIZE_SIZE] copy of the pre-tombstone size field. journal_delete
destructures on Tombstoned and calls restore_ecx_size on .ecj append
failure.

* test(ec): widen admin /health wait to 180s for cold CI

TestEcEndToEnd starts master, 14 volume servers, filer, 2 workers and
admin in sequence, then waited only 60s for admin's HTTP server to come
up. On cold GitHub runners the tail of the earlier subprocess startups
eats most of that budget and the wait occasionally times out (last hit
on run 24374773031). The local fast path is still ~20s total, so the
bump only extends the timeout ceiling, not the happy path.

* test(ec): fork volume servers in parallel in TestEcEndToEnd

startWeed is non-blocking (just cmd.Start()), so the per-process fork +
mkdir + log-file-open overhead for 14 volume servers was serialized for
no reason. On cold CI disks that overhead stacks up and eats into the
subsequent admin /health wait, which is how run 24374773031 flaked.

Wrap the volume-server loop in a sync.WaitGroup and guard runningCmds
with a mutex so concurrent appends are safe. startWeed still calls
t.Fatalf on failure, which is fine from a goroutine for a fatal test
abort; the fail-fast isn't something we rely on for precise ordering.

* ec: fsync ecx before ecj, truncate on failure, harden rebuild

Four correctness fixes covering both volume servers.

1. Durability ordering (Go + Rust). After marking the .ecx tombstone
   we now fsync .ecx before touching .ecj, so a crash between the two
   files cannot leave the journal with an entry for a needle whose
   tombstone is still sitting in page cache. Once the fsync returns,
   the tombstone is the source of truth: reads see "deleted",
   delete_count may under-count by one (benign, idempotent retries)
   but never over-reports. If the fsync itself fails we restore the
   original size bytes and surface the error. The .ecj append is then
   followed by its own Sync so the reported delete_count matches the
   on-disk journal once the write returns.

2. .ecj truncation on append failure. write_all may have extended the
   journal on disk before sync_all / Sync errors out, leaving the
   cached ecj_file_size out of sync with the physical length and
   drifting delete_count permanently after restart. Both languages
   now capture the pre-append size, truncate the file back via
   set_len / Truncate on any write or sync failure, and only then
   restore the .ecx tombstone. Truncation errors are logged — same-fd
   length resets cannot realistically fail — but cannot themselves
   re-sync the files.

3. Atomic rebuild_ecx_from_journal (Rust, dead code today but wired
   up on any future decode path). Previously a failed
   mark_needle_deleted_in_ecx call was swallowed with `let _ = ...`
   and the journal was still removed, silently losing tombstones.
   We now bubble up any non-NotFound error, fsync .ecx after the
   whole replay succeeds, and only then drop and recreate .ecj.
   NotFound is still ignored (expected race between delete and encode).

4. Missing-.ecx hardening (Rust). mark_needle_deleted_in_ecx used to
   return Ok(NotFound) when self.ecx_file was None, hiding a closed or
   corrupt volume behind what looks like an idempotent no-op. It now
   returns an io::Error carrying the volume id so callers (e.g.
   journal_delete) fail loudly instead.

Existing Go and Rust EC test suites stay green.

* ec: make .ecx immutable at runtime; track deletes in memory + .ecj

Refactors both volume servers so the sealed sorted .ecx index is never
mutated during normal operation. Runtime deletes are committed to the
.ecj deletion journal and tracked in an in-memory deleted-needle set;
read-path lookups consult that set to mask out deleted ids on top of
the immutable .ecx record. Mirrors the intended design on both Go and
Rust sides.

EcVolume gains a `deletedNeedles` / `deleted_needles` set seeded from
.ecj in NewEcVolume / EcVolume::new. DeleteNeedleFromEcx /
journal_delete:

  1. Looks the needle up read-only in .ecx.
  2. Missing needle -> no-op.
  3. Pre-existing .ecx tombstone (from a prior decode/rebuild) ->
     mirror into the in-memory set, no .ecj append.
  4. Otherwise append the id to .ecj, fsync, and only then publish
     the id into the set. A partial write is truncated back to the
     pre-append length so the on-disk journal and the in-memory set
     cannot drift.

FindNeedleFromEcx / find_needle_from_ecx now return
TombstoneFileSize when the id is in the in-memory set, even though
the bytes on disk still show the original size.

FileAndDeleteCount:
  fileCount   = .ecx size / NeedleMapEntrySize (unchanged)
  deleteCount = len(deletedNeedles) (was: .ecj size / NeedleIdSize)

The RebuildEcxFile / rebuild_ecx_from_journal decode-time helpers
still fold .ecj into .ecx — that is the one place tombstones land in
the physical index, and it runs offline on closed files. Rust's
rebuild helper now also clears the in-memory set when it succeeds.

Dead code removed on the Rust side: `DeleteOutcome`,
`mark_needle_deleted_in_ecx`, `restore_ecx_size`. Go drops the
runtime `rollbackEcxTombstone` path. Neither helper was needed once
.ecx stopped being a runtime mutation target.

TestEcVolumeSyncEnsuresDeletionsVisible (issue #7751) is rewritten
as TestEcVolumeDeleteDurableToJournal, which exercises the full
durability chain: delete -> .ecj fsync -> FindNeedleFromEcx masks
via the in-memory set -> raw .ecx bytes are *unchanged* -> Close +
RebuildEcxFile folds the journal into .ecx -> raw bytes now show
the tombstone, as CopyFile in the decode path expects.

Chris Lu 10b0bdce02 feat: pass expected_data_size from clients for size-aware assignment (#9032)
* feat: pass expected_data_size from clients for size-aware assignment

Add expected_data_size field to AssignRequest (master proto) and
AssignVolumeRequest (filer proto) so clients can hint how large the
data will be. The master uses this instead of the 1MB default when
tracking pending volume sizes for weighted assignment.

- Add expected_data_size to master.proto AssignRequest
- Add expected_data_size to filer.proto AssignVolumeRequest
- Wire through filer AssignVolume handler
- Wire through HTTP submit handler (uses actual upload size)
- Add ExpectedDataSize to VolumeAssignRequest in operation package
- Topology.PickForWrite accepts optional expectedDataSize parameter

* fix: guard integer conversions in expected_data_size path

- common.go: clamp OriginalDataSize to non-negative before uint64 cast
- topology.go: cap expectedDataSize at math.MaxInt64 before int64 cast

* fix: parse dataSize hint in HTTP /dir/assign and test non-zero expectedDataSize

- HTTP /dir/assign now parses optional "dataSize" query parameter
  and passes it to PickForWrite instead of hardcoded 0
- Add test assertion for PickForWrite with non-zero expectedDataSize

* Match Go throttle boundary: use <= instead of <, fix pretty JSON to 1-space

* Match Go write_needle_blob monotonic appendAtNs via get_append_at_ns

* Match Go VolumeUnmount: idempotent success when volume not found

* Match Go TTL Display: return empty string when unit is Empty

Go checks `t.Unit == Empty` separately and returns "" for TTLs
with nonzero count but Empty unit. Rust only checked is_empty()
(count==0 && unit==0), so count>0 with unit=0 would format as
"5 " instead of "".

* Match Go error behavior for truncated needle data in read_body_v2

Go's readNeedleDataVersion2 returns "index out of range %d" errors
(indices 1-7) when needle body or metadata fields are truncated.
Rust was silently tolerating truncation and returning Ok. Now returns
NeedleError::IndexOutOfRange with the matching index for each field.

* Match Go download throttle: return JSON error instead of plain text

* Match Go crop params: default x1/y1 to 0 when not provided

* Match Go ScrubEcVolume: accumulate total_files from EC shards

* Match Go ScrubVolume: count total_files even on scrub error

* Match Go VolumeEcShardsCopy: set ignore_source_file_not_found for .vif

* Match Go VolumeTailSender: send needle_header on every chunk

* Match Go read_super_block: apply replication override from .vif

* Match Go check_volume_data_integrity: verify all 10 entries, detect trailing corruption

* handlers: align upload parsing with Go

* deps: enable webp support

* Make 5bytes the default feature for idx entry compatibility

* Match Go TTL: preserve original unit when count fits in byte

* Fix EC locate_needle: use get_actual_size for full needle size

* Fix raw body POST: only parse multipart when Content-Type contains form-data

* Match Go ReceiveFile: return protocol errors in response body, not gRPC status

* add docs

* Match Go VolumeEcShardsCopy: append to .ecj file instead of truncating

* Match Go ParsePath: support _delta suffix on file IDs for sub-file addressing

* Match Go chunk manifest: add Accept-Ranges, Content-Disposition, filename fallback, MIME detection

* Match Go privateStoreHandler: use proper JSON error for unsupported methods

* Match Go Destroy: add only_empty parameter to reject non-empty volume deletion

* Fix compilation: set_read_only_persist and set_writable return ()

These methods fire-and-forget save_vif internally, so gRPC callers
should not try to chain .map_err() on the unit return type.

* Match Go SaveVolumeInfo: check writability and propagate errors in save_vif

* Match Go VolumeDelete: propagate only_empty to delete_volume for defense in depth

The gRPC VolumeDelete handler had a pre-check for only_empty but then
passed false to store.delete_volume(), bypassing the store-level check.
Go passes req.OnlyEmpty directly to DeleteVolume. Now Rust does the same
for defense in depth against TOCTOU races (though the store write lock
makes this unlikely).

* Match Go ProcessRangeRequest: return full content for empty/oversized ranges

Go returns nil from ProcessRangeRequest when ranges are empty or total
range size exceeds content length, causing the caller to serve the full
content as a normal 200 response. Rust was returning an empty 200 body.

* Match Go Query: quote JSON keys in output records

Go's ToJson produces valid JSON with quoted keys like {"name":"Alice"}.
Rust was producing invalid JSON with unquoted keys like {name:"Alice"}.

* Match Go VolumeCopy: reject when no suitable disk location exists

Go returns ErrVolumeNoSpaceLeft when no location matches the disk type
and has sufficient space. Rust had an unsafe fallback that silently
picked the first location regardless of type or available space.

* Match Go DeleteVolumeNeedle: check noWriteOrDelete before allowing delete

Go checks v.noWriteOrDelete before proceeding with needle deletion,
returning "volume is read only" if true. Rust was skipping this check.

* Match Go ReceiveFile: prefer HardDrive location for EC and use response-level write errors

Two fixes: (1) Go prefers HardDriveType disk location for EC volumes,
falling back to first location. Returns "no storage location available"
when no locations exist. (2) Write failures are now response-level
errors (in response body) instead of gRPC status errors, matching Go.

* Match Go CopyFile: sync EC volume journal to disk before copying

Go calls ecVolume.Sync() before copying EC volume files to ensure the
.ecj journal is flushed to disk. Added sync_to_disk() to EcVolume and
call it in the CopyFile EC branch.

* Match Go readSuperBlock: propagate replication parse errors

Go returns an error when parsing the replication string from the .vif
file fails. Rust was silently ignoring the parse failure and using the
super block's replication as-is.

* Match Go TTL expiry: remove append_at_ns > 0 guard

Go computes TTL expiry from AppendAtNs without guarding against zero.
When append_at_ns is 0, the expiry is epoch + TTL which is in the past,
correctly returning NotFound. Rust's extra guard skipped the check,
incorrectly returning success for such needles.

* Match Go delete_collection: skip volumes with compaction in progress

Go checks !v.isCompactionInProgress.Load() before destroying a volume
during collection deletion, skipping compacting volumes. Also changed
destroy errors to log instead of aborting the entire collection delete.

* Match Go MarkReadonly/MarkWritable: always notify master even on local error

Go always notifies the master regardless of whether the local
set_read_only_persist or set_writable step fails. The Rust code was
using `?` which short-circuited on error, skipping the final master
notification. Save the result and defer the `?` until after the
notify call.

* Match Go PostHandler: return 500 for all write errors

Go returns 500 (InternalServerError) for all write failures. Rust was
returning 404 for volume-not-found and 403 for read-only volumes.

* Match Go makeupDiff: validate .cpd compaction revision is old + 1

Go reads the new .cpd file's super block and verifies the compaction
revision is exactly old + 1. Rust only validated the old revision.

* Match Go VolumeStatus: check data backend before returning status

Go checks v.DataBackend != nil before building the status response,
returning an error if missing. Rust was silently returning size 0.

* Match Go PostHandler: always include mime field in upload response JSON

Go always serializes the mime field even when empty ("mime":""). Rust was
omitting it when empty due to Option<String> with skip_serializing_if.

* Match Go FindFreeLocation: account for EC shards in free slot calculation

Go subtracts EC shard equivalents when computing available volume slots.
Rust was only comparing volume count, potentially over-counting free
slots on locations with many EC shards.

* Match Go privateStoreHandler: use INVALID as metrics label for unsupported methods

Go records the method as INVALID in metrics for unsupported HTTP methods.
Rust was using the actual method name.

* Match Go volume: add commit_compact guard and scrub data size validation

Two fixes: (1) commit_compact now checks/sets is_compacting flag to
prevent concurrent commits, matching Go's CompareAndSwap guard.
(2) scrub now validates total needle sizes against .dat file size.

* Match Go gRPC: fix TailSender error propagation, EcShardsInfo all slots, EcShardRead .ecx check

Three fixes: (1) VolumeTailSender now propagates binary search errors
instead of silently falling back to start. (2) VolumeEcShardsInfo
returns entries for all shard slots including unmounted. (3)
VolumeEcShardRead checks .ecx index for deletions instead of .ecj.

* Match Go metrics: add BuildInfo gauge and connection tracking functions

Go exposes a BuildInfo Prometheus metric with version labels, and tracks
open connections via stats.ConnectionOpen/Close. Added both to Rust.

* Match Go NeedleMap.Delete: use !is_deleted() instead of is_valid()

Go's CompactMap.Delete checks !IsDeleted() not IsValid(), so needles
with size==0 (live but anomalous) can still be deleted. The Rust code
was using is_valid() which returns false for size==0, preventing
deletion of such needles.

* Match Go fitTtlCount: always normalize TTL to coarsest unit

Go's fitTtlCount always converts to seconds first, then finds the
coarsest unit that fits in one byte (e.g., 120m → 2h). Rust had an
early return for count<=255 that skipped normalization, producing
different binary encodings for the same duration.

* Match Go BuildInfo metric: correct name and add missing labels

Go uses SeaweedFS_build_info (Namespace=SeaweedFS, Subsystem=build,
Name=info) with labels [version, commit, sizelimit, goos, goarch].
Rust had SeaweedFS_volumeServer_buildInfo with only [version].

* Match Go HTTP handlers: fix UploadResult fields, DiskStatus JSON, chunk manifest ETag

- UploadResult.mime: add skip_serializing_if to omit empty MIME (Go uses omitempty)
- UploadResult.contentMd5: only include when request provided Content-MD5 header
- Content-MD5 response header: only set when request provided it
- DiskStatuses: use camelCase field names (percentFree, percentUsed, diskType)
  to match Go's protobuf JSON marshaling
- Chunk manifest: preserve needle ETag in expanded response headers

* Match Go volume: fix version(), integrity check, scrub, and commit_compact

- version(): use self.version() instead of self.super_block.version in
  read_all_needles, check_volume_data_integrity, scan_raw_needles_from
  to respect volumeInfo.version override
- check_volume_data_integrity: initialize healthy_index_size to idx_size
  (matching Go) and continue on EOF instead of returning error
- scrub(): count deleted needles in total_read since they still occupy
  space in the .dat file (matches Go's totalRead += actualSize for deleted)
- commit_compact: clean up .cpd/.cpx files on makeup_diff failure
  (matches Go's error path cleanup)

* Match Go write queue: add 4MB batch byte limit

Go's startWorker breaks the batch at either 128 requests or 4MB of
accumulated write data. Rust only had the 128-request limit, allowing
large writes to accumulate unbounded latency.

* Add TTL normalization tests for Go parity verification

Test that fit_ttl_count normalizes 120m→2h, 24h→1d, 7d→1w even
when count fits in a byte, matching Go's fitTtlCount behavior.

* Match Go FindFreeLocation: account for EC shards in free slot calculation

Go's free volume count subtracts both regular volumes and EC volumes
from max_volume_count. Rust was only counting regular volumes, which
could over-report available slots when EC shards are mounted.

* Match Go EC volume: mark deletions in .ecx and replay .ecj at startup

Go's DeleteNeedleFromEcx marks needles as deleted in the .ecx index
in-place (writing TOMBSTONE_FILE_SIZE at the size field) in addition
to appending to the .ecj journal. Go's RebuildEcxFile replays .ecj
entries into .ecx on startup, then removes the .ecj file.

Rust was only appending to .ecj without marking .ecx, which meant
deleted EC needles remained readable via .ecx binary search. This
fix:
- Opens .ecx in read/write mode (was read-only)
- Adds mark_needle_deleted_in_ecx: binary search + in-place write
- Calls it from journal_delete before appending to .ecj
- Adds rebuild_ecx_from_journal: replays .ecj into .ecx on startup

* Match Go check_all_ec_shards_deleted: use MAX_SHARD_COUNT instead of hardcoded 14

Go's TotalShardsCount is DataShardsCount + ParityShardsCount = 14 by
default, but custom EC configs via .vif can have more shards (up to
MaxShardCount = 32). Using MAX_SHARD_COUNT ensures all shard files
are checked regardless of EC configuration.

* Match Go EC locate: subtract 1 from shard size and use datFileSize override

Go's LocateEcShardNeedleInterval passes shard.ecdFileSize-1 to
LocateData (shards are padded, -1 avoids overcounting large block
rows). When datFileSize is known, Go uses datFileSize/DataShards
instead. Rust was passing the raw shard file size without adjustment.

* Fix TTL parsing and DiskStatus field names to match Go exactly

TTL::read: Go's ReadTTL preserves the original unit (7d stays 7d,
not 1w) and errors on count > 255. The previous normalization change
was incorrect — Go only normalizes internally via fitTtlCount, not
during string parsing.

DiskStatus: Go uses encoding/json on protobuf structs, which reads
the json struct tags (snake_case: percent_free, percent_used,
disk_type), not the protobuf JSON names (camelCase). Revert to
snake_case to match Go's actual output.

* Fix heartbeat: check leader != current master before redirect, process duplicated UUIDs first

Match Go's volume_grpc_client_to_master.go behavior:
1. Only trigger leader redirect when the leader address differs from the
   current master (prevents unnecessary reconnect loops when master confirms
   its own address).
2. Process duplicated_uuids before leader redirect check, matching Go's
   ordering where duplicate UUID detection takes priority.

* Remove SetState version check to match Go behavior

Go's SetState unconditionally applies the state without any version
mismatch check. The Rust version had an extra optimistic concurrency
check that would reject valid requests from Go clients that don't
track versions.

* Fix TTL::read() to normalize via fit_ttl_count matching Go's ReadTTL

Go's ReadTTL calls fitTtlCount which converts to seconds and normalizes
to the coarsest unit that fits in a byte count (e.g. 120m->2h, 7d->1w,
24h->1d). The Rust version was preserving the original unit, producing
different binary encodings on disk and in heartbeat messages.

* Always return Content-MD5 header and JSON field on successful writes

Go always sets Content-MD5 in the response regardless of whether the
request included it. The Rust version was conditionally including it
only when the request provided Content-MD5.

* Include name and size in UploadResult JSON even when empty/zero

Go's encoding/json always includes empty strings and zero values in
the upload response. The Rust version was using skip_serializing_if
to omit them, causing JSON structure differences.

* Include deleted needles in scan_raw_needles_from to match Go

Go's ScanVolumeFileFrom visits ALL needles including deleted ones.
Skipping deleted entries during incremental copy would cause tombstones
to not be propagated, making deleted files reappear on the receiving side.

* Match Go NeedleMap.Delete: always write tombstone to idx file

Go's NeedleMap.Delete unconditionally writes a tombstone entry to the
idx file and updates metrics, even if the needle doesn't exist or is
already deleted. This is important for replication where every delete
operation must produce an idx write. The Rust version was skipping the
tombstone write for non-existent or already-deleted needles.

* Limit MIME type to 255 bytes matching Go's CreateNeedleFromRequest

* Title-case Seaweed-* pair keys to match Go HTTP header canonicalization

* Unify DiskType::Hdd into HardDrive to match Go's single HardDriveType

* Skip tombstone entries in walk_ecx_stats total_size matching Go's Raw()

* Return EMPTY TTL when computed seconds is zero matching Go's fitTtlCount

* Include disk-space-low in Volume.is_read_only() matching Go

* Log error on CIDR parse failure in whitelist matching Go's glog.Errorf

* Log cookie mismatch in gRPC Query matching Go's V(0).Infof

* Fix is_expired volume_size comparison to use < matching Go

Go checks `volumeSize < super_block.SuperBlockSize` (strict less-than),
but Rust used `<=`. This meant Rust would fail to expire a volume that
is exactly SUPER_BLOCK_SIZE bytes.

* Apply Go's JWT expiry defaults: 10s write, 60s read

Go calls v.SetDefault("jwt.signing.expires_after_seconds", 10) and
v.SetDefault("jwt.signing.read.expires_after_seconds", 60). Rust
defaulted to 0 for both, which meant tokens would never expire when
security.toml has a signing key but omits expires_after_seconds.

* Stop [grpc.volume].ca from overriding [grpc].ca matching Go

Go reads the gRPC CA file only from config.GetString("grpc.ca"), i.e.
the [grpc] section. The [grpc.volume] section only provides cert and
key. Rust was also reading ca from [grpc.volume] which would silently
override the [grpc].ca value when both were present.

* Fix free_volume_count to use EC shard count matching Go

Was counting EC volumes instead of EC shards, which underestimates EC
space usage. One EC volume with 14 shards uses ~1.4 volume slots, not 1.
Now uses Go's formula: ((max - volumes) * DataShardsCount - ecShardCount) / DataShardsCount.

* Include preallocate in compaction space check matching Go

Go uses max(preallocate, estimatedCompactSize) for the free space check.
Rust was only using the estimated volume size, which could start a
compaction that fails mid-way if preallocate exceeds the volume size.

* Check gzip magic bytes before setting Content-Encoding matching Go

Go checks both Accept-Encoding contains "gzip" AND IsGzippedContent
(data starts with 0x1f 0x8b) before setting Content-Encoding: gzip.
Rust only checked Accept-Encoding, which could incorrectly declare
gzip encoding for non-gzip compressed data.

* Only set upload response name when needle HasName matching Go

Go checks reqNeedle.HasName() before setting ret.Name. Rust always set
the name from the filename variable, which could return the fid portion
of the path as the name for raw PUT requests without a filename.

* Treat MaxVolumeCount==0 as unlimited matching Go's hasFreeDiskLocation

Go's hasFreeDiskLocation returns true immediately when MaxVolumeCount
is 0, treating it as unlimited. Rust was computing effective_free as
<= 0 for max==0, rejecting the location. This could fail volume
creation during early startup before the first heartbeat adjusts max.

* Read lastAppendAtNs from deleted V3 entries in integrity check

Go's doCheckAndFixVolumeData reads AppendAtNs from both live entries
(verifyNeedleIntegrity) and deleted tombstones (verifyDeletedNeedleIntegrity).
Rust was skipping deleted entries, which could result in a stale
last_append_at_ns if the last index entry is a deletion.

* Return empty body for empty/oversized range requests matching Go

Go's ProcessRangeRequest returns nil (empty body, 200 OK) when
parsed ranges are empty or combined range size exceeds total content
size. The Rust buffered path incorrectly returned the full file data
for both cases. The streaming path already handled this correctly.

* Dispatch ScrubEcVolume by mode matching Go's INDEX/LOCAL/FULL

Go's ScrubEcVolume switches on mode: INDEX calls v.ScrubIndex()
(ecx integrity only), LOCAL calls v.ScrubLocal(), FULL calls
vs.store.ScrubEcVolume(). Rust was ignoring the mode and always
running verify_ec_shards. Now INDEX mode checks ecx index integrity
(sorted overlap detection + file size validation) without shard I/O,
while LOCAL/FULL modes run the existing shard verification.

* Fix TTL test expectation: 7d normalizes to 1w matching Go's fitTtlCount

Go's ReadTTL calls fitTtlCount which normalizes to the coarsest unit
that fits: 7 days = 1 week, so "7d" becomes {Count:1, Unit:Week}
which displays as "1w". Both Go and Rust normalize identically.

* Add version mismatch check to SetState matching Go's State.Update

Go's State.Update compares the incoming version with the stored
version and returns "version mismatch" error if they differ. This
provides optimistic concurrency control. The Rust implementation
was accepting any version unconditionally.

* Use unquoted keys in Query JSON output matching Go's json.ToJson

Go's json.ToJson produces records with unquoted keys like
{score:12} not {"score":12}. This is a custom format used
internally by SeaweedFS for query results.

* Fix TTL test expectation in VolumeNeedleStatus: 7d normalizes to 1w

Same normalization as the HTTP test: Go's ReadTTL calls fitTtlCount
which converts 7 days to 1 week.

* Include ETag header in 304 Not Modified responses matching Go behavior

Go sets ETag on the response writer (via SetEtag) before the
If-Modified-Since and If-None-Match conditional checks, so both
304 response paths include the ETag header. The Rust implementation
was only adding ETag to 200 responses.

* Remove needle-name fallback in chunk manifest filename resolution

Go's tryHandleChunkedFile only falls back from URL filename to
manifest name. Rust had an extra fallback to needle.name that
Go does not perform, which could produce different
Content-Disposition filenames for chunk manifests.

* Validate JWT nbf (Not Before) claim matching Go's jwt-go/v5

Go's jwt.ParseWithClaims validates the nbf claim when present,
rejecting tokens whose nbf is in the future. The Rust jsonwebtoken
crate defaults validate_nbf to false, so tokens with future nbf
were incorrectly accepted.

* Set isHeartbeating to true at startup matching Go's VolumeServer init

Go unconditionally sets isHeartbeating: true in the VolumeServer
struct literal. Rust was starting with false when masters are
configured, causing /healthz to return 503 until the first
heartbeat succeeds.

* Call store.close() on shutdown matching Go's Shutdown()

Go's Shutdown() calls vs.store.Close() which closes all volumes
and flushes file handles. The Rust server was relying on process
exit for cleanup, which could leave data unflushed.

* Include server ID in maintenance mode error matching Go's format

Go returns "volume server %s is in maintenance mode" with the
store ID. Rust was returning a generic "maintenance mode" message.

* Fix DiskType test: use HardDrive variant matching Go's HddType=""

Go maps both "" and "hdd" to HardDriveType (empty string). The
Rust enum variant is HardDrive, not Hdd. The test referenced a
nonexistent Hdd variant causing compilation failure.

* Do not include ETag in 304 responses matching Go's GetOrHeadHandler

Go sets ETag at L235 AFTER the If-Modified-Since and If-None-Match
304 return paths, so Go's 304 responses do not include the ETag header.
The Rust code was incorrectly including ETag in both 304 response paths.

* Return 400 on malformed query strings in PostHandler matching Go's ParseForm

Go's r.ParseForm() returns HTTP 400 with "form parse error: ..." when
the query string is malformed. Rust was silently falling back to empty
query params via unwrap_or_default().

* Load EC volume version from .vif matching Go's NewEcVolume

Go sets ev.Version = needle.Version(volumeInfo.Version) from the .vif
file. Rust was always using Version::current() (V3), which would produce
wrong needle actual size calculations for volumes created with V1 or V2.

* Sync .ecx file before close matching Go's EcVolume.Close

Go calls ev.ecxFile.Sync() before closing to ensure in-place deletion
marks are flushed to disk. Without this, deletion marks written via
MarkNeedleDeleted could be lost on crash.

* Validate SuperBlock extra data size matching Go's Bytes() guard

Go checks extraSize > 256*256-2 and calls glog.Fatalf to prevent
corrupt super block headers. Rust was silently truncating via u16 cast,
which would write an incorrect extra_size field.

* Update quinn-proto 0.11.13 -> 0.11.14 to fix GHSA-6xvm-j4wr-6v98

Fixes Dependency Review CI failure: quinn-proto < 0.11.14 is vulnerable
to unauthenticated remote DoS via panic in QUIC transport parameter
parsing.

* Skip TestMultipartUploadUsesFormFieldsForTimestampAndTTL for Go server

Go's r.FormValue() cannot read multipart text fields after
r.MultipartReader() consumes the body, so ts/ttl sent as multipart
form fields only work with the Rust volume server. Skip this test
when VOLUME_SERVER_IMPL != "rust" to fix CI failure.

* Flush .ecx in EC volume sync_to_disk matching Go's Sync()

Go's EcVolume.Sync() flushes both the .ecj journal and the .ecx index
to disk. The Rust version only flushed .ecj, leaving in-place deletion
marks in .ecx unpersisted until close(). This could cause data
inconsistency if the server crashes after marking a needle deleted in
.ecx but before close().

* Remove .vif file in EC volume destroy matching Go's Destroy()

Go's EcVolume.Destroy() removes .ecx, .ecj, and .vif files. The Rust
version only removed .ecx and .ecj, leaving orphaned .vif files on
disk after EC volume destruction (e.g., after TTL expiry).

* Fix is_expired to use <= for SuperBlockSize check matching Go

Go checks contentSize <= SuperBlockSize to detect empty volumes (no
needles). Rust used < which would incorrectly allow a volume with
exactly SuperBlockSize bytes (header only, no data) to proceed to
the TTL expiry check and potentially be marked as expired.

* Fix read_append_at_ns to read timestamps from tombstone entries

Go reads the full needle body for all entries including tombstones
(deleted needles with size=0) to extract the actual AppendAtNs
timestamp. The Rust version returned 0 early for size <= 0 entries,
which would cause the binary search in incremental copy to produce
incorrect results for positions containing deleted needles.

Now uses get_actual_size to compute the on-disk size (which handles
tombstones correctly) and only returns 0 when the actual size is 0.

* Add X-Request-Id response header matching Go's requestIDMiddleware

Go sets both X-Request-Id and x-amz-request-id response headers.
The Rust server only set x-amz-request-id, missing X-Request-Id.

* Add skip_serializing_if for UploadResult name and size fields

Go's UploadResult uses json:"name,omitempty" and json:"size,omitempty",
omitting these fields from JSON when they are zero values (empty
string / 0). The Rust struct always serialized them, producing
"name":"" and "size":0 where Go would omit them.

* Support JSONP/pretty-print for write success responses

Go's writeJsonQuiet checks for callback (JSONP) and pretty query
parameters on all JSON responses including write success. The Rust
write success path used axum::Json directly, bypassing JSONP and
pretty-print support. Now uses json_result_with_query to match Go.

* Include actual limit in file size limit error message

Go returns "file over the limited %d bytes" with the actual limit
value included. Rust returned a generic "file size limit exceeded"
without the limit value, making it harder to debug.

* Extract extension from 2-segment URL paths for image operations

Go's parseURLPath extracts the file extension from all URL formats
including 2-segment paths like /vid,fid.jpg. The Rust version only
handled 3-segment paths (/vid/fid/filename.ext), so extensions in
2-segment paths were lost. This caused image resize/crop operations
requested via query params to be silently skipped for those paths.

* Add size_hint to TrackedBody so throttled downloads get Content-Length

TrackedBody (used for download throttling) did not implement
size_hint(), causing HTTP/1.1 to fall back to chunked transfer
encoding instead of setting Content-Length. Go always sets
Content-Length explicitly for non-range responses.

* Add Last-Modified, pairs, and S3 headers to chunk manifest responses

Go sets Last-Modified, needle pairs, and S3 pass-through headers on
the response writer BEFORE calling tryHandleChunkedFile. Since the
Rust chunk manifest handler created fresh response headers and
returned early, these headers were missing from chunk manifest
responses. Now passes last_modified_str into the chunk manifest
handler and applies pairs and S3 pass-through query params
(response-cache-control, response-content-encoding, etc.) to the
chunk manifest response headers.

* Fix multipart fallback to use first part data when no filename

Go reads the first part's data unconditionally, then looks for a
part with a filename. If none found, Go uses the first part's data
(with empty filename). Rust only captured parts with filenames, so
when no part had a filename it fell back to the raw multipart body
bytes (including boundary delimiters), producing corrupt needle data.

* Set HasName and HasMime flags for empty values matching Go

Go's CreateNeedleFromRequest sets HasName and HasMime flags even when
the filename or MIME type is empty (len < 256 is true for len 0).
Rust skipped empty values, causing the on-disk needle format to
differ: Go-written needles include extra bytes for the empty name/mime
size fields, changing the serialized needle size in the idx entry.
This ensures binary format compatibility between Go and Rust servers.

* Add is_stopping guard to vacuum_volume_commit matching Go

Go's CommitCompactVolume (store_vacuum.go L53-54) checks
s.isStopping before committing compaction to prevent file
swaps during shutdown. The Rust handler was missing this
check, which could allow compaction commits while the
server is stopping.

* Remove disk_type from required status fields since Go omits it

Go's default DiskType is "" (HardDriveType), and protobuf's omitempty
tag causes empty strings to be dropped from JSON output.

* test: honor rust env in dual volume harness

* grpc: notify master after volume lifecycle changes

* http: proxy to replicas before download-limit timeout

* test: pass readMode to rust volume harnesses

* fix store free-location predicate selection

* fix volume copy disk placement and heartbeat notification

* fix chunk manifest delete replication

* fix write replication to survive client disconnects

* fix download limit proxy and wait flow

* fix crop gating for streamed reads

* fix upload limit wait counter behavior

* fix chunk manifest image transforms

* fix has_resize_ops to check width/height > 0 instead of is_some()

Go's shouldResizeImages condition is `width > 0 || height > 0`, so
`?width=0` correctly evaluates to false. Rust was using `is_some()`
which made `?width=0` evaluate to true, unnecessarily disabling
streaming reads for those requests.

* fix Content-MD5 to only compute and return when provided by client

Go only computes the MD5 of uncompressed data when a Content-MD5
header or multipart field is provided. Rust was always computing and
returning it. Also fix the mismatch error message to include size,
matching Go's format.

* fix save_vif to compute ExpireAtSec from TTL

Go's SaveVolumeInfo always computes ExpireAtSec = now + ttlSeconds
when the volume has a TTL. The save_vif path (used by set_read_only
and set_writable) was missing this computation, causing .vif files
to be written without the correct expiration timestamp for TTL volumes.

* fix set_writable to not modify no_write_can_delete

Go's MarkVolumeWritable only sets noWriteOrDelete=false and persists.
Rust was additionally setting no_write_can_delete=has_remote_file,
which could incorrectly change the write mode for remote-file volumes
when the master explicitly asks to make the volume writable.

* fix write_needle_blob_and_index to error on too-small V3 blob

Go returns an error when the needle blob is too small for timestamp
patching. Rust was silently skipping the patch and writing the blob
with a stale/zero timestamp, which could cause data integrity issues
during incremental replication that relies on AppendAtNs ordering.

* fix VolumeEcShardsToVolume to validate dataShards range

Go validates that dataShards is > 0 and <= MaxShardCount before
proceeding with EC-to-volume reconstruction. Without this check,
a zero or excessively large data_shards value could cause confusing
downstream failures.

* fix destroy to use VolumeError::NotEmpty instead of generic Io error

The dedicated NotEmpty variant exists in the enum but was not being
used. This makes error matching consistent with Go's ErrVolumeNotEmpty.

* fix SetState to persist state to disk with rollback on failure

Go's State.Update saves VolumeServerState to a state.pb file after
each SetState call, and rolls back the in-memory state if persistence
fails. Rust was only updating in-memory atomics, so maintenance mode
would be lost on server restart. Now saves protobuf-encoded state.pb
and loads it on startup.

* fix VolumeTierMoveDatToRemote to close local dat backend after upload

Go calls v.LoadRemoteFile() after saving volume info, which closes
the local DataBackend before transitioning to remote storage. Without
this, the volume holds a stale file handle to the deleted local .dat
file, causing reads to fail until server restart.

* fix VolumeTierMoveDatFromRemote to close remote dat backend after download

Go calls v.DataBackend.Close() and sets DataBackend=nil after removing
the remote file reference. Without this, the stale remote backend
state lingers and reads may not discover the newly downloaded local
.dat file until server restart.

* fix redirect to use internal url instead of public_url

Go's proxyReqToTargetServer builds the redirect Location header from
loc.Url (the internal URL), not publicUrl. Using public_url could
cause redirect failures when internal and external URLs differ.

* fix redirect test and add state_file_path to integration test

Update redirect unit test to expect internal url (matching the
previous fix). Add missing state_file_path field to the integration
test VolumeServerState constructor.

* fix FetchAndWriteNeedle to await all writes before checking errors

Go uses a WaitGroup to await all writes (local + replicas) before
checking errors. Rust was short-circuiting on local write failure,
which could leave replica writes in-flight without waiting for
completion.

* fix shutdown to send deregister heartbeat before pre_stop delay

Go's StopHeartbeat() closes stopChan immediately on interrupt, causing
the heartbeat goroutine to send the deregister heartbeat right away,
before the preStopSeconds delay. Rust was only setting is_stopping=true
without waking the heartbeat loop, so the deregister was delayed until
after the pre_stop sleep. Now we call volume_state_notify.notify_one()
to wake the heartbeat immediately.

* fix heartbeat response ordering to check duplicate UUIDs first

Go processes heartbeat responses in this order: DuplicatedUuids first,
then volume options (prealloc/size limit), then leader redirect. Rust
was applying volume options before checking for duplicate UUIDs, which
meant volume option changes would take effect even when the response
contained a duplicate UUID error that should cause an immediate return.

* fix(deps): update aws-lc-sys 0.38.0 → 0.39.0 to resolve security advisories

Bumps aws-lc-rs 1.16.1 → 1.16.2, pulling in aws-lc-sys 0.39.0 which
fixes GHSA-394x-vwmw-crm3 (X.509 Name Constraints wildcard/unicode
bypass) and GHSA-9f94-5g5w-gf6r (CRL Distribution Point scope check
logic error).

* fix: match Go Content-MD5 mismatch error message format

Go uses "Content-MD5 did not match md5 of file data expected [X]
received [Y] size Z" while Rust had a shorter format. Match the
exact Go error string so clients see identical messages.

* fix: match Go Bearer token length check (> 7, not >= 7)

Go requires len(bearer) > 7 ensuring at least one char after
"Bearer ". Rust used >= 7 which would accept an empty token.

* fix(deps): drop legacy rustls 0.21 to resolve rustls-webpki GHSA-pwjx-qhcg-rvj4

aws-sdk-s3's default "rustls" feature enables tls-rustls in
aws-smithy-runtime, which pulls in legacy-rustls-ring (rustls 0.21
→ rustls-webpki 0.101.7, moderate CRL advisory). Replace with
explicit default-https-client which uses only rustls 0.23 /
rustls-webpki 0.103.9.

* fix: use uploaded filename for auto-compression extension detection

Go extracts the file extension from pu.FileName (the uploaded
filename) for auto-compression decisions. Rust was using the URL
path, which typically has no extension for SeaweedFS file IDs.

* fix: add CRC legacy Value() backward-compat check on needle read

Go double-checks CRC: n.Checksum != crc && uint32(n.Checksum) !=
crc.Value(). The Value() path is a deprecated transform for compat
with seaweed versions prior to commit 056c480eb. Rust had the
legacy_value() method but wasn't using it in validation.

* fix: remove /stats/* endpoints to match Go (commented out since L130)

Go's volume_server.go has the /stats/counter, /stats/memory, and
/stats/disk endpoints commented out (lines 130-134). Remove them
from the Rust router along with the now-unused whitelist_guard
middleware.

* fix: filter application/octet-stream MIME for chunk manifests

Go's tryHandleChunkedFile (L334) filters out application/octet-stream
from chunk manifest MIME types, falling back to extension-based
detection. Rust was returning the stored MIME as-is for manifests.

* fix: VolumeMarkWritable returns error before notifying master

Go returns early at L200 if MarkVolumeWritable fails, before
reaching the master notification at L206. Rust was notifying master
even on failure, creating inconsistent state where master thinks
the volume is writable but local marking failed.

* fix: check volume existence before maintenance in MarkReadonly/Writable

Go's VolumeMarkReadonly (L239-241) and VolumeMarkWritable (L253-255)
look up the volume first, then call makeVolumeReadonly/Writable which
checks maintenance. Rust was checking maintenance first, returning
"maintenance mode" instead of "not found" for missing volumes.

* feat: implement ScrubVolume mark_broken_volumes_readonly (PR #8360)

Add the mark_broken_volumes_readonly flag from PR #8360:
- Sync proto field (tag 3) to local volume_server.proto
- After scrubbing, if flag is set, call makeVolumeReadonly on each
  broken volume (notify master, mark local readonly, notify again)
- Collect errors via joined error semantics matching Go's errors.Join
- Factor out make_volume_readonly helper reused by both
  VolumeMarkReadonly and ScrubVolume

Also refactors VolumeMarkReadonly to use the shared helper.

* fix(deps): update rustls-webpki 0.103.9 → 0.103.10 (GHSA-pwjx-qhcg-rvj4)

CRL Distribution Point matching logic fix for moderate severity
advisory about CRLs not considered authoritative.

* test: update integration tests for removed /stats/* endpoints

Replace tests that expected /stats/* routes to return 200/401 with
tests confirming they now fall through to the store handler (400),
matching Go's commented-out stats endpoints.

* docs: fix misleading comment about default offset feature

The comment said "4-byte offsets unless explicitly built with 5-byte
support" but the default feature enables 5bytes. This is intentional
for production parity with Go -tags 5BytesOffset builds. Fix the
comment to match reality.
