Chris Lu 31fb46f693 volume: rebuild a missing .idx from the .dat (#11115)
* volume: rebuild a missing .idx from the .dat

Pointing -dir.idx at a directory that holds no index aborted the whole
volume server: checkIdxFile found no .idx and load() called glog.Fatalf.
Every row of the index is derivable from the .dat, so walk it in append
order and write the index back, which reproduces byte for byte what the
server's own writes had left in the old directory.

* volume: keep the index co-located with the data in the Rust server

Go's load() drops back to the data directory when an .idx already sits
beside the .dat, so naming a --dir.idx does not strand a pre-existing
index. Rust had no such adjustment: it opened the new directory with
create, and the volume came up on an empty index with every needle
invisible.

* volume: rebuild a missing .idx from the .dat in the Rust server

Mirrors the Go side. Rust did not abort on a missing index the way
checkIdxFile did; it opened the new directory with create and mounted the
volume on an empty index, so every needle read as missing while the .dat
still held the data. Walk the .dat in append order and write the index
back, byte for byte what the server's own writes had left behind.

Claude-Session: https://claude.ai/code/session_01BYrb2AdJSckq9FdHuqseDJ

* volume: stop the idx rebuild at a zero-padded .dat tail

An all-zero needle header is unwritten space, not a record. Go's .dat walk
keeps reading past it and would index a truncated data file's tail as
millions of needle 0 rows; the Rust walk already stops there. Stop the Go
rebuild at the same place.

Claude-Session: https://claude.ai/code/session_01BYrb2AdJSckq9FdHuqseDJ

* volume: create the -dir.idx directory when it does not exist

Rust's DiskLocation creates the index directory as it takes it; Go only
resolved the path, so naming a directory that does not exist yet left every
volume unable to open or rebuild its index and took the server down.

Claude-Session: https://claude.ai/code/session_01BYrb2AdJSckq9FdHuqseDJ

* volume: stop the idx rebuild at a torn .dat record

A crash between writing a needle's header and its body leaves a record
whose declared size runs past the end of .dat. Indexing it puts a row in
the .idx that points at bytes that do not exist, which fails every read of
that needle and trips the past-EOF check on the next load. Stop at the
first record that does not fit, in both servers.

Claude-Session: https://claude.ai/code/session_01BYrb2AdJSckq9FdHuqseDJ

* volume: stop the idx rebuild at a negative-size header

A corrupt header whose size field is negative makes the .dat walk advance
backwards: NeedleBodyLength adds the negative size, so the next offset is
lower than the current one. The Go walk then reads at a negative offset and
the rebuild fails, which puts the volume server right back to exiting at
startup; the Rust walk seeks past EOF and truncates the index instead.
A negative size is never a record, so stop there.

Claude-Session: https://claude.ai/code/session_01BYrb2AdJSckq9FdHuqseDJ

* volume: skip a volume whose index cannot be rebuilt, do not exit

glog.Fatalf calls os.Exit(255), so a rebuild that could not write -- a full
or read-only index directory -- put the server right back to dying at
startup for one bad volume. Return the error instead: loadExistingVolume
logs it and skips that volume, which is what the remote-volume branch just
above already does and what the Rust loader has always done.

Claude-Session: https://claude.ai/code/session_01BYrb2AdJSckq9FdHuqseDJ

* volume: create the index directory from the rebuild too

The rebuild is the first thing to write into a fresh -dir.idx, and it runs
before the loaders that create the directory on their way to opening .idx.
Create it in both rebuilds so the ordering does not matter.

* ci: let codespell past the sme variable in the mount tests

weedfs_stream_mutate_error_test.go names its *streamMutateError local
sme, which codespell reads as a misspelling of same/some. It is an
identifier, so exempt it beside the other variable-name entries.

Chris Lu eed3c27d15 volume: cut the memory a server holding millions of volumes still uses (#10999)
* volume: stop the .vif guard depending on which entry the scan handed over

A volume has both an .idx and a .vif, and loadExistingVolume skipped a .vif
next to an .ecx as EC shard metadata. That was only ever correct because
os.ReadDir sorted .idx ahead of .vif: an interrupted encode, where the .idx is
still there, has to reach validateEcVolume to be reclaimed. Ask for the .idx
instead of trusting the order.

Claude-Session: https://claude.ai/code/session_01NWpFUwAJcR2KUENrhLc9Sy

* volume: walk volume directories in batches instead of listing them whole

os.ReadDir builds, and sorts, a slice of every entry before the caller sees
the first one. A disk holding millions of volumes has a .dat, .idx and .vif
per volume, so each startup scan costs hundreds of MB of peak heap that the
runtime is slow to hand back -- and there are several of them before the
first volume loads.

Walk in batches instead, and keep only the entries each scan acts on:
loadAllEcShards now sorts and stats the shard and index files alone rather
than every file on the disk.

Claude-Session: https://claude.ai/code/session_01NWpFUwAJcR2KUENrhLc9Sy

* volume: skip the sibling-.dat scan when no EC volume is loaded

pruneIncompleteEcWithSiblingDat only ever prunes EC volumes that are loaded,
but it first walks every disk and keys a map by every .dat on the server. On
a store with no EC volumes at all that is millions of map entries built to
answer no question.

Claude-Session: https://claude.ai/code/session_01NWpFUwAJcR2KUENrhLc9Sy

* volume: stop keeping a departure message for every volume

The report state held a VolumeShortInformationMessage per volume copy so a
departure could be named, but almost no volume ever departs. Hold a handle to
the identity instead -- volumes share very few distinct ones -- and build the
message on the way out.

Measured over a populated report state: 195 -> 83 bytes per volume.

Claude-Session: https://claude.ai/code/session_01NWpFUwAJcR2KUENrhLc9Sy

* rust volume: stop keeping a whole volume message per volume held

The send loop kept a VolumeInformationMessage for every volume just to notice
mounts and unmounts, and rebuilt the map from scratch on every beat. Keep the
identity a delta names, which is what the Go report state keeps for the same
reason.

Claude-Session: https://claude.ai/code/session_01NWpFUwAJcR2KUENrhLc9Sy

* rust volume: keep only the EC files the shard scan acts on

load_all_ec_shards named every file on the disk twice -- once in the dedup set
and once in the sorted vector -- before deciding it only wanted .ec?? and .ecx.
Filter while reading instead. Mirrors the same change in loadAllEcShards.

Claude-Session: https://claude.ai/code/session_01NWpFUwAJcR2KUENrhLc9Sy

* volume: share the strings every .vif repeats

A tiered volume's .vif names its replication and its backend, and every decode
allocates a fresh copy, so a server holding millions of them holds millions of
copies of the same handful of names. Route them through the interning table
the volume info decode already uses. The remote key names one volume and is
left alone.

Chris Lu 2d25c39da4 volume: resolve the disk IO slow-latency threshold per disk (#10976)
* volume: resolve the disk IO slow-latency threshold per disk

volume.toml keys [volume.disk.io.slow.latency] by disk type, but the
threshold was chosen once per server by switching on the raw -disk flag.
-disk is comma-separated, one entry per -dir, so a multi-disk server
matched no case and silently took the hdd threshold.

Carry the table on DiskIOProbeConfig and resolve it in CheckDiskSpace
from the location's own DiskType. A type with no entry keeps falling
back to the hdd threshold.

* volume: run the disk IO probe on multi-directory volume servers

The probe was disabled whenever more than one -dir was configured,
because a single server-wide slow-latency threshold could not describe
disks of different types. The threshold is per disk now, and the rest of
the probe already is: diskRegistry is keyed by directory, each
DiskLocation runs its own CheckDiskSpace, and Store consults
isDiskUnavailable per location.

* volume: reject duplicate -dir entries

Nothing deduplicated -dir, so the same directory listed twice produced two
DiskLocations that each loaded every volume in it, appending to the same .dat
under two independent locks. Compare directory identity with os.SameFile
rather than the path, so a symlink or bind mount aliasing an earlier entry is
rejected as well.

* volume: cover the per-disk slow-latency handoff

SlowLatencyFor has a test, but nothing asserted that CheckDiskSpace feeds it
the location's own disk type. Probe through a seam so the resolved threshold
is observable, and check hdd, ssd, nvme, the empty type, and an unlisted tag.

Chris Lu a2ffc7aadf heartbeat: keep the master current through collection churn (#10657)
* heartbeat: name departed volumes in delta heartbeats

* master: release the lookup index with a deleted collection

* master: keep a fresh grow safe from the report that raced it

* volume: name the volumes a deleted collection took with it

Deleting a collection left the master to work out what went by omission from
the next full volume list, which it no longer gets: heartbeats carry the whole
list only when the master asks for it. The volumes a bucket's churn creates and
destroys between two of those requests are never named in either direction, so
the master keeps counting their slots as occupied and a cluster that creates
and drops collections quickly runs its free-slot accounting dry -- assigns fail
with no free volumes left while the disk holds a handful of volumes.

The destroy path already knows exactly which volumes it removed, so send them
down the same channel every other deletion uses.

* rust: name the volumes a deleted collection took with it

Mirrors the Go volume server. The notify path derives its deltas by diffing
snapshots, so a collection delete that does not wake it is invisible until the
master next asks for the whole list.

Chris Lu be81b9d5d7 volume: fix EC decode/reconstruct index locality under -dir.idx (#10442)
* volume: fix EC decode/reconstruct index locality under -dir.idx

EC->replicated decode failed under -dir.idx and on multi-disk with "volume not
found on disk". The reconstruct rebuilds the .dat on the data disk but the
on-demand VolumeMount scans only the data directory, matching on .idx/.vif;
with the rebuilt .idx off in the index directory it matched the volume's
leftover EC .vif and skipped the volume as EC metadata.

- Resolve the EC .ecx local-first: prefer the copy co-located with the shards
  over the shared -dir.idx copy, with a non-empty preference so a 0-byte local
  stub still yields to a valid sibling (the cross-disk fallback).
- Co-locate the rebuilt .idx with the .dat at the end of the reconstruct so the
  mount finds it; sweep .ecx/.ecj from both the data and index directories on
  Destroy so a stale copy cannot re-mount as a phantom EC volume.
- Add VolumeConsolidateIndex: once the EC shards are deleted, unmount, move the
  .idx/.sdx from the data disk back to the -dir.idx directory (copy fallback
  across filesystems), and remount. A no-op without -dir.idx.

* volume: tests for EC index locality (local-first .ecx, sweep, consolidate)

- NewEcVolume prefers a non-empty local .ecx over the shared index dir, and a
  0-byte local stub yields to a non-empty shared copy (the #9212 fallback).
- Destroy sweeps .ecx/.ecj from both the data and index directories.
- ConsolidateVolumeIndex moves a co-located index back to the -dir.idx dir and
  keeps the volume mounted; no-op without a separate index dir.
- RenameOrCopyFile moves a file and drops the source.

* volume: relocate the decoded index in place, without a read gap

ConsolidateVolumeIndex previously unmounted the volume, moved the index, and
remounted it. Between the EC-shard delete and the remount the volume had neither
a normal nor an EC form mounted, so a read landing in that window got a
not-found (or was proxied away).

Move the index in place instead: RelocateIndexTo takes the data-file write lock,
closes the needle map and data backend, moves the .idx (and derived .sdx), then
retargets dirIdx and reloads — the same close-swap-load CommitCompact uses. The
volume never leaves the mounted set, so a concurrent read blocks briefly on the
lock rather than failing. The test now writes a needle before consolidating and
reads it back after, proving the in-place reload keeps the volume serving.

* volume: address review — maintenance guard, no orphan on copy failure

- VolumeConsolidateIndex now rejects the request under maintenance mode, like
  VolumeConfigure and the other mutating volume RPCs.
- RenameOrCopyFile rolls the cross-device copy back when the source cannot be
  removed, so a failed move never leaves two divergent copies (the loader would
  keep the data-dir one while the idx-dir orphan goes stale).
- RelocateIndexTo logs a failed reopen-after-failed-move instead of swallowing
  it, since that leaves the volume unusable until the next load.

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 339a597e7e fix(vacuum): crash-safe compaction commit with a durable .cpc marker, fsync-before-rename, and a reload fence (#9944)
* storage: make vacuum/compaction commit crash-safe with a durable .cpc marker

A crash mid-compaction-commit could lose or corrupt volume data. The
two-rename commit (.cpd->.dat, .cpx->.idx) was not atomic, fsync results
were discarded before renaming over a healthy .dat, a stale .ldb could
poison the needle map, and a duplicate/late commit could delete the live
.dat/.idx outright.

Introduce a durable .cpc commit marker so the swap is atomic across a
crash:

- CommitCompact writes and fsyncs the .cpc marker after makeupDiff
  fsyncs the .cpd/.cpx, then runs applyCompactSwap: an existence-guarded
  rename of .cpd->.dat and .cpx->.idx, a directory fsync, removal of the
  stale .ldb/.rdb, and finally removal of the marker.
- reconcileCompactState recovers an interrupted commit on load: roll
  forward (finish the renames) when the marker is present, roll back
  (delete the orphan .cpd/.cpx) when it is absent. It runs from a
  directory pre-pass keyed on .cpd/.cpc existence, since the per-volume
  loader is keyed on .idx/.vif and misses the marker-only and
  already-renamed-.idx states.
- applyCompactSwap verifies BOTH .cpd and .cpx exist before touching the
  live files, so a stale-state commit (including the Windows
  RemoveAll-then-rename path) errors without deleting anything.
- Error-check the fsyncs that gate the swap: the .cpd close-fsync and
  .cpx fsync in copyDataBasedOnIndexFile, the makeupDiff .idx fsync, and
  MemDb.SaveToIdx.
- generateLevelDbFile rebuilds from offset 0 when the stored watermark
  sits past the end of the .idx, instead of replaying zero entries and
  poisoning the needle map.
- removeVolumeFiles and cleanupCompact sweep the .cpc marker; cleanup
  refuses to unlink the temp files while a marker is present.

Mirror the commit-marker, fsync-before-rename, guard, and
load/reconcile logic in the Rust volume server.

* storage: don't reconcile an already-loaded volume's compaction state on reload

reconcileCompactStates runs in loadExistingVolumes, which is re-invoked at
runtime on SIGHUP (Store.LoadNewVolumes). For a volume that is already loaded
and mid-vacuum, its .cpd/.cpx are live temp files, not crash leftovers --
rolling them back would clobber the in-flight compaction (and remove a live
.ldb out from under an open handle). Skip any vid already present in the
volume map; genuine startup recovery runs before any volume is loaded, so the
map is empty then. Mirrored in the Rust volume server.

Also drop the .note keepVif change that crept into this branch; it belongs to
the replica-copy/verify workstream and is restored to master's behavior here
so the two changes don't collide.

* storage: roll a compaction commit forward per-file, not all-or-nothing

A crash after the .cpd->.dat rename but before .cpx->.idx leaves .cpd gone,
.cpx and .cpc present, and a stale .idx. The roll-forward required BOTH temp
files, so it skipped the swap and cleared the marker, pairing the fresh .dat
with the stale .idx (index corruption). Finish whichever temp file remains:
extract finishCompactSwap to rename .cpd->.dat and/or .cpx->.idx independently;
applyCompactSwap keeps the both-present guard for the normal commit. Existence
in the Rust mirror is checked robustly so a transient error never skips the swap.

* seaweed-volume: propagate directory fsync failures on the compaction commit path

fsync_dir dropped every sync_all error, so the commit could proceed with an
undurable marker or rename and a later restart could recover the wrong
generation. Return the error and check it at the commit call sites (marker write
and the swap), matching the Go fsyncDir which already propagates. Directory
fsync stays a no-op on Windows, where it is unsupported.

* storage: overflow-safe stale-watermark check when rebuilding the leveldb index

watermark*NeedleMapEntrySize can overflow uint64 for a corrupted watermark and
wrap below the file size, defeating the stale-.ldb guard. Compare in entries
(watermark > size/NeedleMapEntrySize) instead, which is equivalent and cannot
overflow. LevelDb-backed needle map is Go-only; no Rust mirror.

* storage: propagate idxFile.Close error when writing the compacted index

SaveToIdx writes the .cpx that is renamed to .idx at commit; a discarded Close
error (buffered data not flushed) could leave a partially-written index after a
crash. Surface it in the same durability gate as the fsync.

Chris Lu c2591b4395 fix(replication): verify-before-destroy in VolumeCopy, check.disk, and over-replication trim (#9943)
* volume: verify before destroy in VolumeCopy and replication repair

Four data-safety fixes around copy/repair paths that could destroy or
resurrect data before verifying the source or survivors.

(a) VolumeCopy no longer deletes a pre-existing local replica up front.
The delete is deferred until ReadVolumeFileStatus on the source succeeds,
so a transient source outage (or a retry after one) can no longer wipe a
healthy destination replica. Gated on source readability only; size/count
comparisons are intentionally not used because they invert legitimately
after divergent vacuum/compaction. Mirrored in the Rust volume server.

(b) volume.check.disk no longer resurrects vacuumed-deleted needles. A
key present-and-live on the source but entirely absent on the target is
ambiguous: it may be a genuine missing write, or a needle deleted on the
target and then vacuumed (its index entry and any tombstone are gone). An
individual needle AppendAtNs has no monotonic relation to a vacuum
watermark, so the old cutoff heuristic could not tell them apart. Without
positive proof the absence is a missing write, the safe default is to NOT
push it back. Tradeoff: a real missing write may go unrepaired until a
tombstone-aware path exists, but we never raise back deleted data.

(c) Over-replication trim no longer resurrects needles or removes the
wrong replica. The pre-delete sync now runs read-only (divergence check
only) instead of writing the doomed replica's needles into the survivor.
pickOneReplicaToDelete only ever removes the smallest of multiple healthy
writable replicas; it refuses the trim when doing so would leave only
read-only/integrity-flagged survivors, since file_count>0 alone cannot
prove the survivor's .dat is readable.

(d) Incomplete-volume (.note) cleanup keeps the shared .vif when an .ecx
for the same vid coexists on the disk, so removing an interrupted regular
copy cannot strip a coexisting EC volume's info file. VolumeCopy now
surfaces .note write/remove errors instead of ignoring them. In the Rust
volume server (where a persisting note is actually reachable) the .note
check moves below the empty-stub sweep and EC validation, keeps the .vif
on EC coexistence, and the mount path fails when a .note still persists.

* shell: scope the over-replication writable-survivor guard to the trim path only

The writable-survivor guard (never trim down to a read-only survivor) lived
inside the shared pickOneReplicaToDelete, so it also gated the misplaced-volume
relocation via pickOneMisplacedVolume -- a misplaced read-only volume (e.g. a
full one) would silently stop being rebalanced. Extract pickSmallestReplica
for the relocation path (which deletes-and-recreates and must act on read-only
replicas), and keep the writable-survivor guard only in pickOneReplicaToDelete
used by the over-replication trim.

* seaweed-volume: recompute keep_vif after invalid-EC cleanup in the .note path

keep_vif used the pre-validation ecx_exists snapshot, so when the EC-validation
step above removed the invalid .ecx/shards, the .note cleanup still preserved a
now-orphaned .vif. Re-check .ecx existence at cleanup time, matching the Go
hasEcxFile re-check.

* shell: keep placement when picking an over-replication victim to delete

The trim picked the smallest writable replica without regard to placement, so
it could delete the only replica in a required failure domain (e.g. with "100"
and replicas dc1 + two in dc2, deleting dc1 leaves both survivors in dc2).
Prefer a writable replica whose removal still satisfies placement, falling back
to the smallest writable only when none does.

Chris Lu 34f9b91d69 fix(storage): never let an empty .dat delete healthy distributed EC shards (#9930)
* fix(storage): never let an empty .dat delete healthy distributed EC shards

A leftover empty .dat stub (a phantom from the pre-fix loader; zero
needles) next to a distributed EC volume's local shards made startup
classify the volume as an interrupted local encode: validateEcVolume
requires >= dataShards local shards when a .dat is present, fails with
the 1-2 shards a distributed volume keeps per disk, and the cleanup
deletes those shards -- the only copies of that part of the volume.
Repeated across restart waves this destroys enough shards cluster-wide
to make the volume unrecoverable.

Go:
- loadExistingVolume: hoist the empty-stub sweep above the EC presence
  checks. Previously the .vif-next-to-.ecx guard returned before the
  sweep ever ran, so exactly the dangerous layout (stub + .ecx + local
  shards) kept its stub and then lost its shards in loadAllEcShards.
- validateEcVolume / checkDatFileExists: treat a .dat <= a superblock
  (zero needles) as absent. An empty .dat cannot be the encode source,
  so it must never gate shard deletion; this also covers stubs without
  a .vif, which the sweep cannot prove are EC leftovers.

Rust mirror (seaweed-volume): the same gate in validate_ec_volume and
check_dat_file_exists (the Rust sweep already ran before validation);
the volume-load skip keeps a plain existence check so fresh,
needle-less volumes still load.

Regression tests in Go and Rust reproduce the production layout (a
zero-byte .dat beside .ecx/.ecj and two shards of a 10+4 volume, with
and without a .vif) and fail without the fix with the shards deleted.

* fix(ec): gate source volume deletion on a recoverable shard set

After EC encode, the shell command and the (plugin) worker task refused
to delete the source volume unless every shard was present, and aborted
otherwise -- leaving the source .dat next to live shards, exactly the
mixed state the startup cleanup mishandles.

Replace the full-set requirement with a recoverability gate shared by
both callers (RequireRecoverableShardSet): deleting a non-empty source
.dat requires at least dataShards distinct shards cluster-wide. Below
that the source is kept and the encode fails as before. A degraded but
recoverable set (>= dataShards, < total) now proceeds with a warning
instead of aborting: the missing shards can be rebuilt from the
survivors, while keeping the source would preserve the dangerous mixed
state. Empty stub replicas are still swept unguarded (OnlyEmpty) -- an
empty .dat has nothing to lose.

dataShards/totalShards stay parameters so enterprise custom EC ratios
share the helper verbatim.

Chris Lu 4f8af455bf feat(storage): sweep leftover empty EC .dat stubs on volume server startup (#9927)
* feat(storage): sweep leftover empty EC .dat stubs on volume server startup

An EC volume keeps no local .dat. The pre-fix loader left empty 8-byte
superblock .dat stubs next to EC metadata (one per lone .vif). Left in
place each loads as a phantom empty volume, and the same vid's stub on
two disks of one server blocks Rust startup via the duplicate-vid check
in Store::add_location -- the prior fix stops creating new stubs but does
not clean up existing ones.

On startup, when a .dat is empty (<= a superblock, i.e. zero needles) and
its .vif marks the volume erasure-coded, remove the stub (+ empty .idx)
instead of loading it. The real data is in the EC shards, so the empty
stub holds nothing to lose. Non-EC empty .dat files (e.g. freshly
allocated volumes) are left alone.

Done in both Rust (load_existing_volumes) and Go (loadExistingVolume),
with regression tests that fail without the sweep.

* refactor(storage): extract empty EC .dat stub sweep into its own function

Move the startup stub-sweep into remove_empty_ec_dat_stub (Rust) and
removeEmptyEcDatStub + vifIsEcVolume (Go) for clearer logic, and look up
the .vif in both the data and idx directories (each read at most once) so
a stub is still found when -dir.idx is configured. Adds direct tests for
the idx-directory lookup on both engines.

Chris Lu 1c9039d3ac fix(seaweed-volume): stop EC shard deletion from phantom .dat on restart (#9874)
* fix(seaweed-volume): stop EC shard deletion from phantom .dat on restart

On startup load_existing_volumes() scans .vif/.idx entries (not just
.dat). For distributed EC, a volume's .vif can be mirrored onto a disk
whose .ecx lives on a sibling disk, so the per-disk ecx check is false
and the loader falls through to Volume::new, which always creates the
.dat if missing -> a phantom 8-byte superblock stub. The store-level
prune_incomplete_ec_with_sibling_dat then treats that stub as the
authoritative source and deletes the real EC shards on sibling disks. Go
guards the same case (disk_location.go: 'Without this guard NewVolume
below would create a phantom empty .dat') but only same-disk.

Fix A (root cause): in load_existing_volumes, don't create a .dat during
load. Skip the entry when there is no local .dat AND the .vif does not
reference remote files -- remote-tiered volumes have no local .dat but
must still load via the remote path. Uses the robust check_dat_file_exists
helper so a transient stat error doesn't skip a real volume. New volumes
go through create_volume(). Covers the cross-disk .vif/.ecx split Go's
same-disk hasEcxFile() misses.

Fix B (defense in depth, Go + Rust): when the EC .vif records no source
size (dat_file_size==0), require the sibling .dat to be strictly larger
than a bare superblock, so an empty 8-byte stub can't pass the
credibility gate. Previously it fell back to SUPER_BLOCK_SIZE, which an
8-byte stub exactly meets.

Adds regression tests reproducing the cross-disk lone-.vif phantom and
the 8-byte stub gate; updates an existing prune test to use a real
collection so its .ecx lookup matches the loaders.

* fix(storage): don't create phantom .dat from lone .vif on Go volume load

Mirror Fix A on the Go side. loadExistingVolume scans .vif/.idx entries,
and for distributed EC a .vif can be mirrored onto a disk whose .ecx is
on a sibling disk. The same-disk hasEcxFile() guard does not fire there,
so the loader falls through to NewVolume(createDatIfMissing=true) and
writes an 8-byte phantom .dat, which the sibling-.dat prune then uses to
delete the real EC shards on sibling disks. Skip the entry when there is
no local .dat AND the .vif has no remote file (via MaybeLoadVolumeInfo);
remote-tiered volumes have no local .dat but must still load.

Adds TestLoneVifDoesNotCreatePhantomDat (fails without the guard) and
TestRemoteTier_DiskScanLoadsRemoteOnlyVolume (fails if the guard skips a
remote-only volume).

e3e02d3364 [CheckDisk]: implement disk health detection (#9560)
* [CheckDisk][GRPC]: implement MVP for disk health detection, added timeout for new grpc connections

* fix(volume): build disk health check on every platform

setDiskStatus only existed behind the statfs build tag, so disk.go failed
to compile on windows, openbsd, solaris, netbsd and plan9. Move the timeout
wrapper and failure tracking into the shared disk.go and have each platform's
fillInDiskStatus return an error, so every platform gets the same protection
from a stuck filesystem.

Also restore the uint64(fs.Bavail) cast: Bavail is int64 on freebsd, so the
unguarded multiply broke the freebsd build.

* fix(volume): keep one outstanding statfs probe per disk

A stuck statfs used to leave isChecking cleared by the timeout path, so the
next check spawned another goroutine while the previous one was still blocked
in the syscall, leaking one goroutine per minute on a hung disk. Clear the
flag only when statfs returns and treat an overlapping check as a failure, so
a hung filesystem keeps a single outstanding probe and still gets reported.

* fix(volume): assume disk available until the first health check

isDiskAvailable defaulted to false, and CollectHeartbeat skips locations that
are not available. A freshly started volume server would therefore omit every
volume from its first heartbeats until the async CheckDiskSpace ran, so the
master could briefly treat all of them as missing.

* fix(volume): label the disk error metric by data directory

The new gauge tagged the series with IdxDirectory while every neighbouring
resource gauge uses Directory, so the error series would not line up with them
in dashboards. Also log the underlying error instead of a generic message.

* test(volume): cover disk health success and repeated-failure paths

* fix(volume): make a healthy disk the zero-value default

Track the disk as isDiskUnavailable instead of isDiskAvailable so the safe
state is the zero value, matching isDiskSpaceLow. CollectHeartbeat only skips a
location once a check has actively marked it unavailable, so any DiskLocation
built without running CheckDiskSpace (tests, future call sites) still reports
its volumes instead of silently dropping them.

* feat(disk): detect degraded disks using IO latency probes

* feat(stats): introduce configurable disk I/O health probe with EWMA-based latency detection

* feat(disk): replace EWMA with sliding window algorithm for disk health detection and added user-friendly options

* feat(disk): improve disk health probing and recovery

* feat(volume): configure disk health checks via volume.toml

* fix(volume): Remove disk IO probe CLI options

Chris Lu 3674f9d04d fix(storage): keep EC .vif when deleting a coexisting regular volume (#9723)
* fix(storage): keep EC .vif when deleting a coexisting regular volume

A regular volume and an EC volume for the same id share <base>.vif. When
EC shards are distributed onto a server that still holds the regular
volume — the encode source, or any replica the planner targets — the
post-encode VolumeDelete ran removeVolumeFiles and stripped the shared
.vif, leaving the freshly built EC volume without its info file.

Skip the .vif in removeVolumeFiles when an EC volume for the same id
exists on the disk (mounted, or a sealed .ecx on disk). The regular
volume's .dat/.idx still go; the EC sidecars survive.

A two-server end-to-end test encodes a volume whose source and a stub
replica both also receive shards, and asserts the final on-disk layout:
both .dat/.idx gone, each server holding only its assigned shards plus
.ecx/.vif. Storage unit tests cover the with-EC and no-EC cases, and the
Rust seaweed-volume port carries the same guard and tests.

* test(storage): assert .idx is removed in the no-EC destroy case

Strengthen TestDestroyRemovesVifWhenNoEc to confirm the full regular
volume cleanup (.dat, .idx, .vif) when no EC volume coexists.

Chris Lu 18677a8430 fix(storage): refuse to load .vif-only entry as regular volume when .ecx exists (#9448) (#9461)
fix(storage): refuse to load .vif-only entry as regular volume when .ecx exists

Defensive root-cause fix for issue #9448. The detection-side guard in
the EC plugin worker already breaks the infinite re-encode loop, but
the underlying volume-server state — `.vif` preserved next to EC shards
when the source replica is destroyed — can still re-arm a phantom
regular volume via the MountVolume / LoadVolume path.

In loadExistingVolume, the existing `.ecx`-present check is gated on
the caller passing `skipIfEcVolumesExists=true`. The startup-scan path
(concurrentLoadingVolumes) does pass that flag and correctly skips
the `.vif`. The LoadVolume → loadExistingVolume(…, false, …) path
used by VolumeMount does NOT, so it falls through to NewVolume, which
calls v.load with createDatIfMissing=true and creates a phantom
empty `.dat`. The master then reports the volume as regular and EC
detection re-proposes it.

Hoist the `.ecx`-present check so it runs unconditionally for `.vif`
entries: if the EC index is on the disk, the `.vif` belongs to those
EC shards, never to a regular volume that should be resurrected.
Pure OSS clusters never reach this exact state today (OSS deletes
`.vif` unconditionally during Destroy), but the guard hardens the
load path against any future path that leaves the same state.

Test:
- TestLoadExistingVolumeSkipsVifWhenEcxPresent builds the exact
  post-#9448 disk layout (`.vif` + `.ecx`, no `.dat`) and asserts
  loadExistingVolume(skipIfEcVolumesExists=false) returns false,
  does not create a placeholder `.dat`, and does not register a
  phantom volume in l.volumes.

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.

* Apply suggestion from @gemini-code-assist[bot]

Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com>

* 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 4c88fbfd5e Fix nil pointer crash during concurrent vacuum compaction (#8592)
* check for nil needle map before compaction sync

When CommitCompact runs concurrently, it sets v.nm = nil under
dataFileAccessLock. CompactByIndex does not hold that lock, so
v.nm.Sync() can hit a nil pointer. Add an early nil check to
return an error instead of crashing.

Fixes #8591

* guard copyDataBasedOnIndexFile size check against nil needle map

The post-compaction size validation at line 538 accesses
v.nm.ContentSize() and v.nm.DeletedSize(). If CommitCompact has
concurrently set v.nm to nil, this causes a SIGSEGV. Skip the
validation when v.nm is nil since the actual data copy uses local
needle maps (oldNm/newNm) and is unaffected.

Fixes #8591

* use atomic.Bool for compaction flags to prevent concurrent vacuum races

The isCompacting and isCommitCompacting flags were plain bools
read and written from multiple goroutines without synchronization.
This allowed concurrent vacuums on the same volume to pass the
guard checks and run simultaneously, leading to the nil pointer
crash. Using atomic.Bool with CompareAndSwap ensures only one
compaction or commit can run per volume at a time.

Fixes #8591

* use go-version-file in CI workflows instead of hardcoded versions

Use go-version-file: 'go.mod' so CI automatically picks up the Go
version from go.mod, avoiding future version drift. Reordered
checkout before setup-go in go.yml and e2e.yml so go.mod is
available. Removed the now-unused GO_VERSION env vars.

* capture v.nm locally in CompactByIndex to close TOCTOU race

A bare nil check on v.nm followed by v.nm.Sync() has a race window
where CommitCompact can set v.nm = nil between the two. Snapshot
the pointer into a local variable so the nil check and Sync operate
on the same reference.

* add dynamic timeouts to plugin worker vacuum gRPC calls

All vacuum gRPC calls used context.Background() with no deadline,
so the plugin scheduler's execution timeout could kill a job while
a large volume compact was still in progress. Use volume-size-scaled
timeouts matching the topology vacuum approach: 3 min/GB for compact,
1 min/GB for check, commit, and cleanup.

Fixes #8591

* Revert "add dynamic timeouts to plugin worker vacuum gRPC calls"

This reverts commit 80951934c3.

* unify compaction lifecycle into single atomic flag

Replace separate isCompacting and isCommitCompacting flags with a
single isCompactionInProgress atomic.Bool. This ensures CompactBy*,
CommitCompact, Close, and Destroy are mutually exclusive — only one
can run at a time per volume.

Key changes:
- All entry points use CompareAndSwap(false, true) to claim exclusive
  access. CompactByVolumeData and CompactByIndex now also guard v.nm
  and v.DataBackend with local captures.
- Close() waits for the flag outside dataFileAccessLock to avoid
  deadlocking with CommitCompact (which holds the flag while waiting
  for the lock). It claims the flag before acquiring the lock so no
  new compaction can start.
- Destroy() uses CAS instead of a racy Load check, preventing
  concurrent compaction from racing with volume teardown.
- unmountVolumeByCollection no longer deletes from the map;
  DeleteCollectionFromDiskLocation removes entries only after
  successful Destroy, preventing orphaned volumes on failure.

Chris Lu af4c3fcb31 ec: fall back to data dir when ecx file not found in idx dir (#8541)
* ec: fall back to data dir when ecx file not found in idx dir (#8540)

When -dir.idx is configured after EC encoding, the .ecx/.ecj files
remain in the data directory. NewEcVolume now falls back to the data
directory when the index file is not found in dirIdx.

* ec: add fallback logging and improved error message for ecx lookup

* ec: preserve configured dirIdx, track actual ecx location separately

The previous fallback set ev.dirIdx = dir when finding .ecx in the data
directory, which corrupted IndexBaseFileName() for future writes (e.g.,
WriteIdxFileFromEcIndex during EC-to-volume conversion would write the
.idx file to the data directory instead of the configured index directory).

Introduce ecxActualDir to track where .ecx/.ecj were actually found,
used only by FileName() for cleanup/destroy. IndexBaseFileName() continues
to use the configured dirIdx for new file creation.

* ec: check both idx and data dirs for .ecx in all cleanup and lookup paths

When -dir.idx is configured after EC encoding, .ecx/.ecj files may
reside in the data directory. Several code paths only checked
l.IdxDirectory, causing them to miss these files:

- removeEcVolumeFiles: now removes .ecx/.ecj from both directories
- loadExistingVolume: ecx existence check falls back to data dir
- deleteEcShardIdsForEachLocation: ecx existence check and cleanup
  both cover the data directory
- VolumeEcShardsRebuild: ecx lookup falls back to data directory
  so RebuildEcxFile operates on the correct file

   the pattern used in FromTaskPolicy, preventing external mutation of

3. Add clarifying comment in buildCandidateSets explaining that the

* Fix nil pointer dereference in parseVolumeTags

* Fix NormalizeTagList to return empty slice instead of nil

* optimize: enable immediate EC shard reporting during startup

Ported the immediate EC shard reporting feature from Enterprise to Community version.
This allows the master to be notified about EC shards immediately during volume server startup,
instead of waiting for the first heartbeat.

Changes:
1. Updated NewStore to initialize notification channels BEFORE loading volumes (fixes potential nil panic).
2. Added ecShardNotifyHandler to report EC shards to NewEcShardsChan during startup.
3. Implemented non-blocking channel send for EC reporting to prevent deadlock when loading many EC shards (fixing the enterprise bug 17ac1290c).
4. Updated DiskLocation and EC loading logic to support the callback.

This optimization improves cluster state consistency and startup speed for EC-heavy clusters.

* optimize: report actual EC shard size during startup

* optimize: increase notification channel buffer size to 1024

* optimize: fix variable shadowing in store.go

Chris Lu 3613279f25 Add 'weed mini' command for S3 beginners and small/dev use cases (#7831)
* Add 'weed mini' command for S3 beginners and small/dev use cases

This new command simplifies starting SeaweedFS by combining all components
in one process with optimized settings for development and small deployments.

Features:
- Starts master, volume, filer, S3, WebDAV, and admin in one command
- Volume size limit: 64MB (optimized for small files)
- Volume max: 0 (auto-configured based on free disk space)
- Pre-stop seconds: 1 (faster shutdown for development)
- Master peers: none (single master mode by default)
- Includes admin UI with one worker for maintenance tasks
- Clean, user-friendly startup message with all endpoint URLs

Usage:
  weed mini                    # Use default temp directory
  weed mini -dir=/data        # Custom data directory

This makes it much easier for:
- Developers getting started with SeaweedFS
- Testing and development workflows
- Learning S3 API with SeaweedFS
- Small deployments that don't need complex clustering

* Change default volume server port to 9340 to avoid popular port 8080

* Fix nil pointer dereference by initializing all required volume server fields

Added missing VolumeServerOptions field initializations:
- id, publicUrl, diskType
- maintenanceMBPerSecond, ldbTimeout
- concurrentUploadLimitMB, concurrentDownloadLimitMB
- pprof, idxFolder
- inflightUploadDataTimeout, inflightDownloadDataTimeout
- hasSlowRead, readBufferSizeMB

This resolves the panic that occurred when starting the volume server.

* Fix multiple nil pointer dereferences in mini command

Added missing field initializations for:
- Master options: raftHashicorp, raftBootstrap, telemetryUrl, telemetryEnabled
- Filer options: filerGroup, saveToFilerLimit, concurrentUploadLimitMB,
  concurrentFileUploadLimit, localSocket, showUIDirectoryDelete,
  downloadMaxMBps, diskType, allowedOrigins, exposeDirectoryData, tusBasePath
- Volume options: id, publicUrl, diskType, maintenanceMBPerSecond, ldbTimeout,
  concurrentUploadLimitMB, concurrentDownloadLimitMB, pprof, idxFolder,
  inflightUploadDataTimeout, inflightDownloadDataTimeout, hasSlowRead, readBufferSizeMB
- WebDAV options: tlsPrivateKey, tlsCertificate, filerRootPath
- Admin options: master

These initializations are required to avoid runtime panics when starting components.

* Fix remaining S3 option nil pointers in mini command

* Update mini command: 256MB volume size and add S3 access instructions for beginners

* mini: set default master.volumeSizeLimitMB to 128MB and update help/banner text

* mini: shorten S3 help text to a concise pointer to docs/Admin UI

* mini: remove duplicated component bullet list, use concise sentence

* mini: tidy help alignment and update example usage

* mini: default -dir to current directory

* mini: load initial S3 credentials from env and write IAM config

* mini: use AWS env vars for initial S3 creds; instruct to create via Admin UI if absent

* Improve startup synchronization with channel-based coordination

- Replace fragile time.Sleep delays with robust channel-based synchronization
- Implement proper service dependency ordering (Master → Volume → Filer → S3/WebDAV/Admin)
- Add sync.WaitGroup for goroutine coordination
- Add startup readiness logging for better visibility
- Implement 10-second timeout for admin server startup
- Remove arbitrary sleep delays for faster, more reliable startup
- Services now start deterministically based on dependencies, not timing

This makes the startup process more reliable and eliminates race conditions on slow systems or under load.

* Refactor service startup logic for better maintainability

Extract service startup into dedicated helper functions:
- startMiniServices(): Orchestrates all service startup with dependency coordination
- startServiceWithCoordination(): Starts services with readiness signaling
- startServiceWithoutReady(): Starts services without readiness signaling
- startS3Service(): Encapsulates S3 initialization logic

Benefits:
- Reduced code duplication in runMini()
- Clearer separation of concerns
- Easier to add new services or modify startup sequence
- More testable code structure
- Improved readability with explicit service names and logging

* Remove unused serviceStartupInfo struct type

- Delete the serviceStartupInfo struct that was defined but never used
- Improves code clarity by removing dead code
- All service startup is now handled directly by helper functions

* Preserve existing IAM config file instead of truncating

- Use os.Stat to check if IAM config file already exists
- Only create and write configuration if file doesn't exist
- Log appropriate messages for each case:
  * File exists: skip writing, preserve existing config
  * File absent: create with os.OpenFile and write new config
  * Stat error: log error without overwriting
- Set *miniIamConfig only when new file is successfully created
- Use os.O_CREATE|os.O_WRONLY flags for safe file creation
- Handles file operations with proper error checking and cleanup

* Fix CodeQL security issue: prevent logging of sensitive S3 credentials

- Add createdInitialIAM flag to track when initial IAM config is created from env vars
- Set flag in startS3Service() when new IAM config is successfully written
- Update welcome message to inform user of credential creation without exposing secrets
- Print only the username (mini) and config file location to user
- Never print access keys or secret keys in clear text
- Maintain security while keeping user informed of what was created
- Addresses CodeQL finding: Clear-text logging of sensitive information

* Fix three code review issues in weed mini command

1. Fix deadlock in service startup coordination:
   - Run blocking service functions (startMaster, startFiler, etc.) in separate goroutines
   - This allows readyChan to be closed and prevents indefinite blocking
   - Services now start concurrently instead of sequentially blocking the coordinator

2. Use shared grace.StartDebugServer for consistency:
   - Replace inline debug server startup with grace.StartDebugServer
   - Improves code consistency with other commands (master, filer, etc.)
   - Removes net/http import which is no longer needed

3. Simplify IAM config file cleanup with defer:
   - Use 'defer f.Close()' instead of multiple f.Close() calls
   - Ensures file is closed regardless of which code path is taken
   - Improves robustness and code clarity

* fmt

* Fix: Remove misleading 'service is ready' logs

The previous fix removed 'go' from service function calls but left misleading
'service is ready' log messages. The service helpers now correctly:
- Call fn() directly (blocking) instead of 'go fn()' (non-blocking)
- Remove the 'service is ready' message that was printed before the service
  actually started running
- Services run as blocking goroutines within the coordinator goroutine,
  which keeps them alive while the program runs
- The readiness channels still work correctly because they're closed when
  the coordinator finishes waiting for dependencies

* Update mini.go

* Fix four code review issues in weed mini command

1. Use restrictive file permissions (0600) for IAM config:
   - Changed from 0644 to 0600 when creating iam_config.json
   - Prevents world-readable access to sensitive AWS credentials
   - Protects AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY

2. Remove unused sync.WaitGroup:
   - Removed WaitGroup that was never waited on
   - All services run as blocking goroutines in the coordinator
   - Main goroutine blocks indefinitely with select{}
   - Removes unnecessary complexity without changing behavior

3. Merge service startup helper functions:
   - Combined startServiceWithCoordination and startServiceWithoutReady
   - Made readyChan optional (nil for services without readiness signaling)
   - Reduces code duplication and improves maintainability
   - Both services now use single startServiceWithCoordination function

4. Fix admin server readiness check:
   - Removed misleading timeout channel that never closed at startup
   - Replaced with simple 2-second sleep before worker startup
   - startAdminServer() blocks indefinitely, so channel would only close on shutdown
   - Explicit sleep is clearer about the startup coordination intent

* Fix three code quality issues in weed mini command

1. Define volume configuration as named constants:
   - Added miniVolumeMaxDataVolumeCounts = "0"
   - Added miniVolumeMinFreeSpace = "1"
   - Added miniVolumeMinFreeSpacePercent = "1"
   - Removed local variable assignments in Volume startup
   - Improves maintainability and documents configuration intent

2. Fix deadlock in startServiceWithCoordination:
   - Changed from 'defer close(readyChan)' with blocking fn() to running fn() in goroutine
   - Close readyChan immediately after launching service goroutine
   - Prevents deadlock where fn() never returns, blocking defer execution
   - Allows dependent services to start without waiting for blocking call

3. Improve admin server readiness check:
   - Replaced fixed 2-second sleep with polling the gRPC port
   - Polls up to 20 times (10 seconds total) with 500ms intervals
   - Uses net.DialTimeout to check if port is available
   - Properly handles IPv6 addresses using net.JoinHostPort
   - Logs progress and warnings about connection status
   - More robust than sleep against server startup timing variations

4. Add net import for network operations (IPv6 support)

Also fixed IAM config file close error handling to properly check error
from f.Close() and log any failures, preventing silent data loss on NFS.

* Document environment variable setup for S3 credentials

Updated welcome message to explain two ways to create S3 credentials:

1. Environment variables (recommended for quick setup):
   - Set AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
   - Run 'weed mini -dir=/data'
   - Creates initial 'mini' user credentials automatically

2. Admin UI (for managing multiple users and policies):
   - Open http://localhost:23646 (Admin UI)
   - Add identities to create new S3 credentials

This gives users clear guidance on the easiest way to get started with S3
credentials while also explaining the more advanced option for multiple users.

* Print welcome message after all services are running

Moved the welcome message printing from immediately after startMiniServices()
to after all services have been started and are ready. This ensures users see
the welcome message only after startup is complete, not mixed with startup logs.

Changes:
- Extract welcome message logic into printWelcomeMessage() function
- Call printWelcomeMessage() after startMiniServices() completes
- Change message from 'are starting' to 'are running and ready to use'
- This provides cleaner startup output without interleaved logs

* Wait for all services to complete before printing welcome message

The welcome message should only appear after all services are fully running and
the worker is connected. This prevents the message from appearing too early before
startup logs complete.

Changes:
- Pass allServicesReady channel through startMiniServices()
- Add adminReadyChan to track when admin/worker startup completes
- Signal allServicesReady when admin service is fully ready
- Wait for allServicesReady in runMini() before printing welcome message
- This ensures clean output: startup logs first, then welcome message once ready

Now the user sees all startup activity, then a clear welcome message when
everything is truly ready to use.

* Fix welcome message timing: print after worker is fully started

The welcome message was printing too early because allServicesReady was being
closed when the Admin service goroutine started, not when it actually completed.
The Admin service launches startMiniAdminWithWorker() which is a blocking call
that doesn't return until the worker is fully connected.

Now allServicesReady is passed through to startMiniWorker() which closes it
after the worker successfully starts and connects to the admin server.

This ensures the welcome message only appears after:
- Master is ready
- Volume server is ready
- Filer is ready
- S3 service is ready
- WebDAV service is ready
- Admin server is ready
- Worker is connected and running

All startup logs appear first, then the clean welcome message at the end.

* Wait for S3 and WebDAV services to be ready before showing welcome message

The welcome message was printing before S3 and WebDAV servers had fully
initialized. Now the readiness flow is:

1. Master → ready
2. Volume → ready
3. Filer → ready
4. S3 → ready (signals s3ReadyChan)
5. WebDAV → ready (signals webdavReadyChan)
6. Admin/Worker → starts, then waits for both S3 and WebDAV
7. Welcome message prints (all services truly ready)

Changes:
- Add s3ReadyChan and webdavReadyChan to service startup
- Pass S3 and WebDAV ready channels through to Admin service
- Admin/Worker waits for both S3 and WebDAV before closing allServicesReady
- This ensures welcome message appears only when all services are operational

* Admin service should wait for Filer, S3, and WebDAV to be ready

Admin service depends on Filer being operational since it uses the filer
for credential storage. It also makes sense to wait for S3 and WebDAV
since they are user-facing services that should be ready before Admin.

Updated dependencies:
- Admin now waits for: Master, Filer, S3, WebDAV
- This ensures all critical services are operational before Admin starts
- Welcome message will print only after all services including Admin are ready

* Add initialization delay for S3 and WebDAV services

S3 and WebDAV servers need extra time to fully initialize and start listening
after their service functions are launched. Added a 1-second delay after
launching S3 and WebDAV goroutines before signaling readiness.

This ensures the welcome message doesn't print until both services have
emitted their startup logs and are actually serving requests.

* Increase service initialization wait times for more reliable startup

- Increase S3 and WebDAV initialization delay from 1s to 2s to ensure they emit startup logs before welcome message
- Add 1s initialization delay for Filer to ensure it's listening
- Increase admin gRPC polling timeout from 10s to 20s to ensure admin server is fully ready
- This ensures welcome message prints only after all services are fully initialized and ready to accept requests

* Increase service wait time to 10 seconds for reliable startup

All services now wait 10 seconds after launching to ensure they are fully initialized and ready before signaling readiness to dependent services. This ensures the welcome message prints only after all services have fully started.

* Replace fixed 10s delay with intelligent port polling for service readiness

Instead of waiting a fixed 10 seconds for each service, now polls the service
port to check if it's actually accepting connections. This eliminates unnecessary
waiting and allows services to signal readiness as soon as they're ready.

- Polls each service port with up to 30 attempts (6 seconds total)
- Each attempt waits 200ms before retrying
- Stops polling immediately once service is ready
- Falls back gracefully if service is unknown
- Significantly faster startup sequence while maintaining reliability

* Replace channel-based coordination with HTTP pinging for service readiness

Instead of using channels to coordinate service startup, now uses HTTP GET requests
to ping each service endpoint to check if it's ready to accept connections.

Key changes:
- Removed all readiness channels (masterReadyChan, volumeReadyChan, etc.)
- Simplified startMiniServices to use sequential HTTP polling for each service
- startMiniService now just starts the service with logging
- waitForServiceReady uses HTTP client to ping service endpoints (max 6 seconds)
- waitForAdminServerReady uses HTTP GET to check admin server availability
- startMiniAdminWithWorker and startMiniWorker simplified without channel parameters

Benefits:
- Cleaner, more straightforward code
- HTTP pinging is more reliable than TCP port probing
- Services signal readiness through their HTTP endpoints
- Eliminates channel synchronization complexity

* log level

* Remove overly specific comment from volume size limit in welcome message

The '(good for small files)' comment is too limiting. The 128MB volume size
limit works well for general use cases, not just small files. Simplified the
message to just show the value.

* Ensure allServicesReady channel is always closed via defer

Add 'defer close(allServicesReady)' at the start of startMiniAdminWithWorker
to guarantee the channel is closed on ALL exit paths (normal and error).
This prevents the caller waiting on <-allServicesReady from ever hanging,
while removing the explicit close() at the successful end prevents panic
from double-close.

This makes the code more robust by:
- Guaranteeing channel closure even if worker setup fails
- Eliminating the possibility of caller hanging on errors
- Following Go defer patterns for resource cleanup

* Enhance health check polling for more robust service coordination

The service startup already uses HTTP health checks via waitForServiceReady()
to verify services are actually accepting connections. This commit improves
the health check implementation:

Changes:
- Elevated success logging to Info level so users see when services become ready
- Improved error messages to clarify that health check timeouts are not fatal
- Services continue startup even if health checks timeout (they may still work)
- Consistent handling of health check results across all services

This provides better visibility into service startup while maintaining the
existing robust coordination via HTTP pinging rather than just TCP port checks.

* Implement stricter error handling for robust mini server startup

Apply all PR review feedback to ensure the mini server fails fast and clearly
when critical components cannot start:

Changes:
1. Remove redundant miniVolumeMinFreeSpacePercent constant
   - Simplified util.MustParseMinFreeSpace() call to use single parameter

2. Make service readiness checks fatal errors:
   - Master, Volume, Filer, S3, WebDAV health check failures now return errors
   - Prevents partially-functional servers from running
   - Caller can handle errors gracefully instead of continuing with broken state

3. Make admin server readiness fatal:
   - Admin gRPC availability is critical for worker startup
   - Use glog.Fatalf to terminate with clear error message

4. Improve IAM config error handling:
   - Treat all file operation failures (stat, open, write, close) as fatal
   - Prevents silent failures in S3 credential setup
   - User gets immediate feedback instead of authentication issues later

5. Use glog.Fatalf for critical worker setup errors:
   - Failed to create worker directory, task directories, or worker instance
   - Failed to create admin client or start worker
   - Ensures mini server doesn't run in broken state

This ensures deterministic startup: services succeed completely or fail with
clear, actionable error messages for the user.

* Make health checks non-fatal for graceful degradation and improve IAM file handling

Address PR feedback to make the mini command more resilient for development:

1. Make health check failures non-fatal
   - Master, Volume, Filer, S3, WebDAV health checks now log warnings but allow startup
   - Services may still work even if health check endpoints aren't immediately available
   - Aligns with intent of a dev-focused tool that should be forgiving of timing issues
   - Only prevents startup if startup coordination or critical errors occur

2. Improve IAM config file handling
   - Refactored to guarantee file is always closed using separate error variables
   - Opens file once and handles write/close errors independently
   - Maintains strict error handling while improving code clarity
   - All file operation failures still cause fatal errors (as intended)

This makes startup more graceful while maintaining critical error handling for
fundamental failures like missing directories or configuration errors.

* Fix code quality issues in weed mini command

- Fix pointer aliasing: use value copy (*miniBindIp = *miniIp) instead of pointer assignment
- Remove misleading error return from waitForServiceReady() function
- Simplify health check callers to call waitForServiceReady() directly without error handling
- Remove redundant S3 option assignments already set in init() block
- Remove unused allServicesReady parameter from startMiniWorker() function

* Refactor welcome message to use template strings and add startup delay

- Convert welcome message to constant template strings for cleaner code
- Separate credentials instructions into dedicated constant
- Add 500ms delay after worker startup to allow full initialization before welcome message
- Improves output cleanliness by avoiding log interleaving with welcome message

* Fix code style issues in weed mini command

- Fix indentation in IAM config block (lines 424-432) to align with surrounding code
- Remove unused adminServerDone channel that was created but never read

* Address code review feedback for robustness and resource management

- Use defer f.Close() for IAM file handling to ensure file is closed in all code paths, preventing potential file descriptor leaks
- Use 127.0.0.1 instead of *miniIp for service readiness checks to ensure checks always target localhost, improving reliability in environments with firewalls or complex network configurations
- Simplify error handling in waitForAdminServerReady by using single error return instead of separate write/close error variables

* Fix function declaration formatting

- Separate closing brace of startS3Service from startMiniAdminWithWorker declaration with blank line
- Move comment to proper position above function declaration
- Run gofmt for consistent formatting

* Fix IAM config pointer assignment when file already exists

- Add missing *miniIamConfig = iamPath assignment when IAM config file already exists
- Ensures S3 service is properly pointed to the existing IAM configuration
- Retains logging to inform user that existing configuration is being preserved

* Improve pointer assignments and worker synchronization

- Simplify grpcPort and dataDir pointer assignments by directly dereferencing and assigning values instead of taking address of local variables
- Replace time.Sleep(500ms) with proper TCP-based polling to wait for worker gRPC port readiness
- Add waitForWorkerReady function that polls worker's gRPC port with max 6-second timeout
- Add net package import for TCP connection checks
- Improves code idiomaticity and synchronization robustness

* Refactor and simplify error handling for maintainability

- Remove unused error return from startMiniServices (always returned nil)
- Update runMini caller to not expect error from startMiniServices
- Refactor init() into component-specific helper functions:
  * initMiniCommonFlags() for common options
  * initMiniMasterFlags() for master server options
  * initMiniFilerFlags() for filer server options
  * initMiniVolumeFlags() for volume server options
  * initMiniS3Flags() for S3 server options
  * initMiniWebDAVFlags() for WebDAV server options
  * initMiniAdminFlags() for admin server options
- Significantly improves code readability and maintainability
- Each component's flags are now in dedicated, focused functions
