* volume: forward fsync=true to replicas in ReplicatedWrite
When a write request carries fsync=true, only the primary volume server
flushed to disk: the replica fan-out URL in ReplicatedWrite only carried
type/ttl/ts/cm, so replicas always wrote without fsync even when the
client explicitly requested a durable write.
Forward the fsync request parameter to the replica volume servers so a
durable write means every replica has flushed to disk, not just the
primary. Replicas without fsync are untouched (zero behavior change).
* storage: flush a durable write inline while stopping
The fsync flag on the write path really selects the async batch worker,
and it was switched off once the store is stopping. So a fsync=true write
landing during the pre-stop drain got acked without ever being flushed -
and now that ReplicatedWrite forwards fsync, that covers replicas too.
Flush it inline instead of queueing it. The drain keeps accepting writes,
which is the whole point of preStopSeconds, and the ack still means the
.dat is on disk. If the fsync fails, the append comes back off the .dat
and the needle map goes back to what it pointed at before, so nothing
resolves to an offset past the truncated end.
* storage: make the store's stopping flag atomic
SetStopping runs on the signal handler goroutine while the write and
vacuum paths read the flag, so every read of it was racy. Nothing about
the shutdown ordering changes; only the flag itself is now safe to read.
* topology: check the errors the replication test was dropping
The mock replica ignored its response write and the mock master ignored
whatever Serve returned, so a broken mock would have shown up as a
confusing timeout rather than a failure. Also drops the explicit listener
close: grpc.Server.Stop already closes the listener it was given.

A zero-data needle lands in .dat as a size-0 record, byte-identical to
a delete marker, so scans that walk .dat count it as deleted. Once in
1024 writes newRandomNeedle produced one, and the idx-head repair then
skipped a row TestRepairIdxHeadTombstones_ReadOnlyVolume expected back.
* [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

makeupDiff replays post-snapshot changes onto the compacted volume. For a
replayed deletion it appended a tombstone to the new .dat but recorded the
.idx entry with offset 0. When that deletion is the last replayed change the
tombstone lands at the .dat tail, and the post-commit integrity check skips
offset-0 entries, so it sees 32 trailing bytes it can't account for and flips
the volume read-only, reloading it as a SortedFileNeedleMap instead of the
writable map.
Record the tombstone's real .dat offset, matching the normal delete path; the
needle map still treats it as deleted off the negative size, so lookups are
unchanged. Mirror the same fix into the Rust volume server.
* fix(volume): keep vacuum running past dangling .idx entries
Vacuum compaction aborted entirely on the first .idx entry whose offset
pointed past the end of the .dat file, surfacing as `cannot hydrate
needle from file: EOF` and stalling progress on every other volume.
In both Go and Rust:
- During compaction, skip an unreadable needle and continue. The bytes
it pointed at were already unreachable via reads, so dropping the
index reference makes the post-vacuum volume consistent. Real EIO
still bails out so a disk fault is not silently papered over.
- At volume load, do a single linear scan of the .idx and confirm
every (offset + actual size) fits inside .dat. The pre-existing
integrity check only looked at the last 10 entries, so deeper
corruption (e.g. left over from a crashed batched write) went
undetected and only surfaced later as a vacuum EOF. A failure now
marks the volume read-only at load time so an operator can react.
Refs #8928
* fix(volume): only skip permanent-corruption needle reads during vacuum
Address PR review feedback (gemini-code-assist + coderabbit):
The original patch skipped any non-EIO read failure, which would silently
drop needles on transient errors — Windows hardware bad-sector errors
(ERROR_CRC etc.) never surface as syscall.EIO; tiered-storage network
timeouts and EROFS would also slip through and shrink the volume.
Switch to an explicit whitelist of permanent-corruption shapes:
- Add needle.ErrorCorrupted sentinel and wrap CRC and "index out of
range" errors with %w so callers can match via errors.Is.
- copyDataBasedOnIndexFile now skips only when the read failure is
io.EOF, io.ErrUnexpectedEOF, ErrorSizeMismatch, ErrorSizeInvalid,
or ErrorCorrupted. Anything else (real disk faults, environmental
errors, Windows hardware codes) aborts the compaction so an
operator notices.
- Mirror the same whitelist in the Rust volume server, matching on
io::ErrorKind::UnexpectedEof and the NeedleError corruption variants
(SizeMismatch, CrcMismatch, IndexOutOfRange, TailTooShort).
Also add `defer v.Close()` in TestVerifyIndexFitsInDat so Windows
t.TempDir() cleanup can release the .dat/.idx handles.
Refs #8928
* fix(volume): wrap entry-not-found size-mismatch with ErrorSizeMismatch
Address PR review: the fallback branch in ReadBytes returned an
unwrapped fmt.Errorf, so isSkippableNeedleReadError (and any caller
using errors.Is(..., ErrorSizeMismatch)) could not match it. Wrap
with %w so the whitelist applies, while leaving the existing direct
sentinel return for the OffsetSize==4 / offset<MaxPossibleVolumeSize
retry path unchanged so ReadData's `err == ErrorSizeMismatch` retry
still triggers.
Refs #8928
* fix(volume): integrate dangling-idx check into existing index load walk
Address PR review (gemini-code-assist, medium): the structural .idx
check used to do a second linear scan of the index file at every volume
load, doubling the disk-I/O cost on servers managing many volumes.
Track the largest (offset + actual size) seen during the existing
needle-map load walks (`LoadCompactNeedleMap`, `NewLevelDbNeedleMap`,
`NewSortedFileNeedleMap`'s `newNeedleMapMetricFromIndexFile`,
`DoOffsetLoading`) on a new `MaximumNeedleEnd` field on `mapMetric`,
exposed as `MaxNeedleEnd()` on the NeedleMapper interface.
`volume.load()` then compares `nm.MaxNeedleEnd()` to the .dat size
after the load is complete — pure numeric comparison, no extra I/O.
The standalone `verifyIndexFitsInDat` helper and its caller in
`CheckVolumeDataIntegrity` are removed; the test that used to drive
the helper directly now exercises the new path via
`LoadCompactNeedleMap`.
Mirror the same change in the Rust volume server: track
`max_needle_end` on `NeedleMapMetric`, expose via `max_needle_end()`
on `CompactNeedleMap`, `RedbNeedleMap`, and the `NeedleMap` enum.
The Rust load walk already happens in `load_from_idx` for both map
kinds, so the structural check becomes free.

* Process .ecj deletions during EC decode and vacuum decoded volume (#8798)
When decoding EC volumes back to normal volumes, deletions recorded in
the .ecj journal were not being applied before computing the dat file
size or checking for live needles. This caused the decoded volume to
include data for deleted files and could produce false positives in the
all-deleted check.
- Call RebuildEcxFile before HasLiveNeedles/FindDatFileSize in
VolumeEcShardsToVolume so .ecj deletions are merged into .ecx first
- Vacuum the decoded volume after mounting in ec.decode to compact out
deleted needle data from the .dat file
- Add integration tests for decoding with non-empty .ecj files
* storage: add offline volume compaction helper

* ec: compact decoded volumes before deleting shards
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* ec: address PR review comments
- Fall back to data directory for .ecx when idx directory lacks it
- Make compaction failure non-fatal during EC decode
- Remove misleading "buffer: 10%" from space check error message
* ec: collect .ecj from all shard locations during decode
Each server's .ecj only contains deletions for needles whose data
resides in shards held by that server. Previously, sources with no
new data shards to contribute were skipped entirely, losing their
.ecj deletion entries. Now .ecj is always appended from every shard
location so RebuildEcxFile sees the full set of deletions.
* ec: add integration tests for .ecj collection during decode
TestEcDecodePreservesDeletedNeedles: verifies that needles deleted
via VolumeEcBlobDelete are excluded from the decoded volume.
TestEcDecodeCollectsEcjFromPeer: regression test for the fix in
collectEcShards. Deletes a needle only on a peer server that holds
no new data shards, then verifies the deletion survives decode via
.ecj collection.
* ec: address review nits in decode and tests
- Remove double error wrapping in mountDecodedVolume
- Check VolumeUnmount error in peer ecj test
- Assert 404 specifically for deleted needles, fail on 5xx

* fix: close volumes and EC shards in tests to prevent Windows cleanup failures
On Windows, t.TempDir() cleanup fails when test files are still open
because Windows enforces mandatory file locking. Add defer v.Close(),
defer store.Close(), and EC volume cleanup to ensure all file handles
are released before temp directory removal.
