It adds regression tests, benchmarks, changelog entries, and implementation records. ChangesVolume stack hardening
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR changes volume discovery, automount, mount cleanup, and label updates, but the current head still contains paths that can crash refreshes, race while partition state changes, permanently disable automount after transient failures, leave stale mount directories, and fail to update labels optimistically. These issues can cause stale or unavailable volume state, so merge should be blocked until the production-impacting defects are fixed. Sequence Diagram(s)sequenceDiagram

- H8: hardware-cache aliasing via shared partition map pointer - H9: event-handler errors swallowed at emit sites - H10: lazy hardware discovery inside HTTP request path - F6: hardcoded isReadOnlyMode on SmartStatusPanel - Verified B2/H4/H6 semantics against converter and u-root source
- Create docs/refactors/048-volume-hardening.md tracking doc - Baseline: backend 0 failures, frontend 728 tests passed - All impacted functions already covered; no missing tests
- Full read-site and refreshVersion inventory for volume_service.go - External consumers, test literals, and commit sequence for B1
- Replace map with mutex-protected struct (AddOrUpdate, Snapshot, Len) - Add refresh version counter and NewDiskMapFrom constructor - Convert call sites and tests; add concurrent-access race test
- `persistMountPoint` merges into existing DB record - Discovery ADD merges automount flag + flags from DB row - Tests: settings survive ADD; share association kept
- Add GetMountPointsForPartition DiskMap helper - Scope stale loop to the processed partition only - Regression test proves no phantom mount points
- Parse procfs once per refresh cycle and share the snapshot across one PartitionEvent per disk instead of one per partition - Add batch mode + mount data sync with DB persistence - Add H2 regression test and benchmarks for batched refresh
- Remove unreachable duplicate DevicePath nil/empty guard (the first check at function top already returned for nil paths) - Add 11 focused MountVolume tests: 65.3% -> 89.8% coverage
Partial PATCHes only update the patched fields at DB level (GORM skips nil struct fields), but the converter unconditionally nil-wiped Flags, Data and ExportedShare on the in-memory record, which was then pushed back into the response DTO and the disk cache. Reload the row from the DB after Updates so the response and cache reflect persisted state. - downgrade affected==0 to a no-op debug log instead of misleading 404 - add 7 tests: empty-patch no-op, partial-patch keeps flags at DB and response level, record-not-found, fallback cache branches - coverage PatchMountPointSettings 39.6% -> 75.0%
GetVolumesData masked getVolumesData failures by returning an empty slice, so the UI rendered an empty volume list on hardware errors. Change the signature to ([]*dto.Disk, errors.E), map the failure to HTTP 500 in ListVolumes, and fall back to a nil partition-resolution context in PatchMountPointSettings. - update all mock and direct call sites - add tests: /volumes 500 on hardware error, service error propagation, cached fast path (GetVolumesData 100% coverage)
- normal unmount now passes no flags, so a busy filesystem surfaces the real error instead of silently detaching - force unmount uses MNT_DETACH (lazy), guaranteed to succeed - mount dir removal only on non-lazy unmount (stays valid while the filesystem detaches underneath) - add volume_mount_manager_test.go: flag-capturing mock tests + busy-error propagation + nil mount point guard
- Break aliasing with the 30-min hardware cache (concurrent map read/write panic risk vs HDIdle handler, cache pollution) - Race test: 1000 concurrent GetVolumesData + cache readers under -race
- EmitDisk/EmitPartition now return errors.E; discard moved out of the bus - Batch partition handler returns first DB sync failure - Emit sites log failures with context (fire-and-forget kept)
- OnStart warmup logs warn instead of returning discovery error - add boot warmup + warm-request-skips-hardware tests - add boot warmup failure does not fail app start test
- isReadOnlyMode={readOnly} instead of hardcoded false
- add RTL tests: disabled in read-only, enabled otherwise

193-210: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winThe dispatched cache update never changes the cache.
updatePartitionLabelInDisksis pure. It copies the disks and returns a new array (lines 46-83). It never mutates its input. Inside theupdateQueryDatarecipe the returned array is discarded, and the Immer draft stays unchanged. The optimistic label update is therefore a no-op, and the tree only shows the new label after the invalidation-driven refetch.Return the produced array from the recipe, or mutate the draft in place.
🐛 Proposed fix: return the new state from the recipe
dispatch( - sratApi.util.updateQueryData("getApiVolumes", undefined, (draft) => { - if (Array.isArray(draft)) { - updatePartitionLabelInDisks(draft, partitionId, label); - } - }), + sratApi.util.updateQueryData("getApiVolumes", undefined, (draft) => { + if (!Array.isArray(draft)) return; + for (const disk of draft) { + for (const partition of Object.values(disk.partitions || {})) { + if (partition?.id === partitionId) { + partition.name = label; + } + } + } + }), );Note: the assertion in

Two behaviors are worth noting:
- If
queueorerrorChanis closed, the matchingselectcase is always ready. The loop then spins at full CPU until the timer expires.- The function never returns early. Every shutdown pays the full

56-63: 🚀 Performance & Scalability | 🔵 Trivial | ⚖️ Poor tradeoffConsider coalescing rescans triggered by udev bursts.
handleDiskUdevRemoveEventruns a fullInvalidateHardwareInfoplusgetVolumesDatasynchronously in the udev event loop. The same pattern applies to the disk-add and partition-add branches. When the kernel emits a burst (for example a multi-partition drive being removed, or a hub disconnect), each event starts a complete hardware rescan while the loop cannot read the next event. The enlarged 64-slot queue absorbs the burst, but the rescans still run one per event.A short debounce (collect events for a few hundred milliseconds, then run one rescan) would bound the work per burst. This is a follow-up improvement, not a blocker.

Inline comments:
In `@backend/src/api/filesystems.go`:
- Around line 497-505: Extend the SetPartitionLabel test coverage with a case
where EmitDisk returns an error after the label update completes. Assert that
the endpoint still reports success and the cached partition label reflects the
new value, covering the failure path around the eventBus.EmitDisk call.
In `@backend/src/dto/disk_map.go`:
- Around line 111-122: Update DiskMap.AddOrUpdate to return the established
invalid-parameter error when either the receiver m or disk argument d is nil,
before accessing d.Id or locking m.mu; preserve the existing ID validation and
insertion behavior for valid inputs.
- Around line 55-79: Protect nested Disk state during enumeration by ensuring
All and Snapshot do not expose shared Disk pointers whose Partitions maps can be
mutated after DiskMap.mu is released. Prefer returning deep-copied Disk values,
or introduce and use a safe enumeration API in diskStatsService.updateDiskStats
and VolumeService that holds the appropriate synchronization while reading
Partitions; preserve existing nil and map-copy behavior.
In `@backend/src/service/udev_channel_drain_test.go`:
- Around line 63-70: Update TestDrainUdevChannels_BoundedWhenIdle to assert
completion within a tolerance close to the configured 100*time.Millisecond
timeout instead of allowing 2 seconds; retain the existing start-time
measurement and drainUdevChannels call.
In `@backend/src/service/volume_mount_manager.go`:
- Around line 176-185: Update the unmount cleanup in unmountVolume to remove
md.Path after forced unmounts as well, eliminating the if !force guard while
preserving the existing warning and debug logging. Ensure
handlePartitionUdevRemoveEvent’s forced-unmount path leaves mountPath absent as
expected by the test.
In `@backend/src/service/volume_service_internal_test.go`:
- Around line 36-41: Update the test fixture setup to use newTestVolumeService
instead of constructing VolumeService directly, ensuring fs_service and eventBus
are initialized for snapshots with partitions and keeping it consistent with the
reconciliation tests.
In `@backend/src/service/volume_service_reconcile_test.go`:
- Around line 21-36: Guard fakeReconcileHardware’s phase and calls fields with a
sync.Mutex, locking access in GetHardwareInfo and InvalidateHardwareInfo. Add
accessors for reading these values under the same mutex, and update the test
assertions currently reading hw.phase and hw.calls directly to use those
accessors.
In `@backend/src/service/volume_service_test.go`:
- Around line 1306-1312: Update all three suite.disks.Get call sites in the test
to retain the ok result and immediately assert it with suite.Require().True
before dereferencing the returned disk, preserving the existing disk state
checks.
In `@backend/src/service/volume_service.go`:
- Around line 923-964: Guard both procfsGetMounts call sites in
handlePartitionEvent, covering the batch and single-partition branches, using
the same nil-safe behavior as getVolumesData. When the function is unavailable
and MountInfos is nil, avoid invoking it and preserve the existing partition
synchronization flow without introducing a panic.
- Around line 655-663: Guard the partition count used by the disk-processing
trace log before dereferencing disk.Partitions, using a nil-safe count of zero
when no partitions are present. Preserve the existing handling in the disk
refresh flow, including the later disk.Partitions nil check.
- Around line 1161-1206: Add a cooldown-based recovery to allowAutomountAttempt:
when an exhausted automountRetryState has remained past the configured reset
interval, delete or reset that path’s state and permit a fresh attempt budget;
otherwise preserve terminal and backoff behavior. Add and initialize the
reset-duration configuration in VolumeService, keeping it zero in retry-focused
tests for deterministic assertions, and ensure expired entries are removed to
prevent unbounded map growth.
- Around line 806-840: Update manageProvisionalRechecks so an exhausted recheck
state is retained rather than reset to nil, preventing a new budget from being
allocated on subsequent calls; only clear pendingRecheck when no whole-disk
synthesized disks remain. Before assigning a newly scheduled timer to
pendingRecheck.timer, stop any existing timer to prevent overlapping recheck
chains.
In `@docs/refactors/048-volume-hardening.md`:
- Around line 5-9: Update the refactor status header in the volume hardening
document to reflect completion: use the final completion date of August 18,
2026, mark the status as complete with no remaining tasks, and point the linked
task to the completed task document using the existing filename convention.
In `@docs/tasks/048_volume-stack-hardening-review.md`:
- Around line 564-567: Update the F5 entry in the test coverage table to
reference frontend/src/pages/volumes/__tests__/utils.test.ts instead of
Volumes.test.tsx, matching the executable reorder-stability coverage recorded in
Task 18.
In `@docs/tasks/TASK_STATUS.md`:
- Line 35: Complete the truncated “Next” entry in TASK_STATUS.md by adding the
missing validation scenario after “(Scenar”, or remove the incomplete
parenthetical if no scenario is intended. Keep the task reference and existing
validation instructions unchanged.
- Around line 16-18: Update Task 043, “Zeroconf mDNS Registration from Addon
(Lab),” so its progress matches its completed status by changing the progress to
15 / 15 tasks, or move it to In Progress and adjust the related summary counts
consistently.

- Around line 19-30: Update drainUdevChannels to use two-value receives for
queue and errorChan, and disable each channel case after its channel is closed
so the select loop cannot spin; retain the existing timer-based full-timeout
behavior.
In `@backend/src/service/volume_mount_manager.go`:
- Around line 162-172: Document that the force parameter passed through the
unmount flow requests lazy detachment (MNT_DETACH) when true, rather than a
forced unmount. Update the Unmount API documentation and the HTTP force query
parameter description, including the “Force umount operation” text, while
preserving the existing false, force argument ordering.
In `@backend/src/service/volume_service_internal_test.go`:
- Around line 65-72: Rename TestRunProvisionalRecheck_LogsOnGetVolumesDataError
to reflect its current assertions, such as
TestRunProvisionalRecheck_ContinuesOnGetVolumesDataError; do not describe
unverified logging behavior.
In `@backend/src/service/volume_service_reconcile_test.go`:
- Around line 178-186: Replace the fixed time.Sleep after the recheck completion
in the reconciliation test with a bounded require.Never stability check that
repeatedly verifies hw.calls remains maxRechecks+1 over a short interval, then
retain the exact call-count assertion and partition visibility assertions.
In `@backend/src/service/volume_service_test.go`:
- Around line 1498-1519: Reduce the race test’s loop count from 1000 to a
low-hundreds value while preserving both concurrent goroutine paths and the
final WaitGroup synchronization. Keep the GetVolumesData and raw hardware-cache
access behavior unchanged.
In `@backend/src/service/volume_service_udev_linux.go`:
- Around line 56-63: Coalesce udev-triggered rescans across burst events instead
of running them synchronously for every disk or partition add/remove event.
Update the event handling around handleDiskUdevRemoveEvent and the corresponding
add branches to debounce events for a few hundred milliseconds, then perform one
hardware invalidation and volume refresh while preserving existing event
handling behavior.
In `@frontend/src/pages/volumes/components/__tests__/VolumeDetailsPanel.test.tsx`:
- Around line 337-392: Extract the duplicated GET /api/disk/:id/smart/test MSW
handler from the two SMART self-test tests into the shared customHandlers
module, then import and reuse that handler in both tests. Preserve its
deterministic idle, non-running response and remove the local duplicate
declarations.
In `@frontend/src/pages/volumes/components/__tests__/VolumeMountDialog.test.tsx`:
- Around line 392-398: Wrap the post-click assertions in the VolumeMountDialog
test with waitFor, waiting for the asynchronous handleCloseSubmit flow to invoke
mockClose and disable mountButton; keep the existing assertion expectations
unchanged.

Volume stack hardening: phantom volumes, cache correctness, automount resilience
Closes the full
docs/tasks/048_volume-stack-hardening-review.mdscope (Tasks 0–24).Problem
During boot, the Home Assistant custom component can render "phantom" whole-disk entries / errors in the volumes tree. The root cause is a chain of five defects that left synthesized whole-disk entries permanently visible:
getVolumesDatanever evicted disks that disappeared from a later hardware snapshot, so a disk seen once stayed in the cache forever.bus + "-" + serial + suffix, previously alsouuid.NewString()) that can never match the realby-idmap key, so real disk removals were silently ignored.findDiskForDevicePathfallback — when no partition matched a device path it returned an arbitrary disk instead ofnil.RefreshVersion— moot once disks are replaced wholesale.Boot race
onStartcallsgetVolumesDatabeforeHACoreReady; at that pointhwDisks == niland the early-return deliberately skips pruning. The HASTARTsnapshot lacks partition children, so the disk is synthesized as a whole-disk entry and then frozen without any invalidation.Fix (Tasks 0–24 summary)
