Two producer paths double-booked the same damage across repair records
(backlog#1894 axis A):
- The scanner's corrupt-metadata branch fired a durable MRF journal
intent, an immediate High heal request, and a pending-ledger entry for
the same object. When the MRF intent is accepted into the channel it
already covers the repair durably (the consumer files a High Metadata
heal and the journal replays it across restarts), so the immediate
request and ledger entry are dropped in that case; on delivery failure
(feature disabled, channel uninitialized, or full) the old immediate
request + ledger path runs unchanged, keeping the repair safety net.
- The read path filed a journal intent before the read-repair
reservation check, so a burst of reads failing on one object booked a
journal record per retry. The intent now rides the submission: it is
filed only when the sighting wins the dedup TTL, next to the Low
request, via a new optional mrf_intent field on
ReadRepairHealSubmission (None keeps the historical no-intent
behavior for the other read-repair call sites).
Manager dedup-key semantics are untouched; the fix is that competing
producers stop double-booking. With RUSTFS_HEAL_MRF_ENABLE off both
paths behave exactly as before.

The scanner's pending-heal ledger and the MRF journal tracked the same
damaged objects with no cross-talk: once the consumer landed an intent
with the heal manager, the ledger's retry entry for that target kept
re-submitting a heal the manager already owned (backlog#1894 axis B).
Fan the acceptance out: both dispatch sites in the MRF queue (the live
consumer and the startup replay) record a compact MrfRepairedEvent
(bucket, object, version bytes) in a bounded process-wide ring owned by
rustfs-common. The scanner drains its own bucket's notices at the top
of retry_pending_scanner_heals and clears the matching Object-kind
ledger entries in one batched retain + sync (a mass-recovery first
sweep must not turn into thousands of full-table ledger clones on the
scan task), with nil notice UUIDs mapping to None per the repo-wide
defensive-UUID invariant so unversioned entries match unversioned
notices only. Notices are best-effort by design — a lost or capped-out
notice leaves the entry to expire through its own attempts/age limits,
because the ledger is a retry oracle, not a source of truth; other
buckets' notices stay queued for their own scanners. Neither persistent
format changes; old nodes that keep double-booking remain harmless.

HealType::MRF (a #1664-era "metadata repair file" task kind) had no
production construction site left: its only builder lived in the
HealEvent -> HealRequest converter, and the HealEvent/HealEventHandler
queue itself had zero production references — both were superseded by
the MrfIntent pipeline (mrf_queue.rs), which produces Object/Metadata/
ECDecode requests and never an MRF task. The dead path nevertheless
carried ~700 lines: the whole event.rs module, the heal_mrf executor,
a dedup-key arm, an overlap arm with the "\u{0}mrf" sentinel bucket
hack, per-kind labels, and an empty MrfRuntime::record_accept shell.
Deleting the variant is compile-time safe: HealType has no Serialize
derive, the protos wire enums carry no heal-type discriminant (the
receiver rebuilds it from HealChannelRequest fields), the MRF journal
encodes MrfKind (1/2/3), and the scanner pending-heal ledger uses its
own kind enum — none of them can name an MRF task.
Also resolves the in-crate naming clash where "MRF" denoted both the
dead task kind and the live mission-repair-feed loop; the loop stays,
the task kind goes.

`audit_runtime_facade_stops_empty_replay_workers` called the stop path and checked nothing, the same shape as the notify facade test in the previous commit. It now asserts the worker manager is empty afterwards and that a second call — which shutdown paths make — stays harmless.
The two heal timestamp tests bound their fields to `_`. Both timestamps come from `SystemTime::now().duration_since(UNIX_EPOCH).unwrap_or_default()`, so a pre-epoch clock yields 0; binding to `_` could not tell that apart from a real reading, which is precisely what the tests said they were guarding. They now require the value to be past 2020-01-01, and `last_update` not to predate `start_time`.
`test_config_parsing_with_multiple_instances` is left as it was — see the issue comment. Asserting on it turned up something bigger than a missing assertion.

* feat(heal): incremental heal status cursors and typed overlap policy (HS-06)
Incremental results: every retained result item now carries a monotonic
sequence number. The status query accepts a client cursor (sinceSeq on
the admin wire, Option<u64> internally) and returns only newer items,
plus nextSeq (the next cursor) and minSeq (the oldest retained
sequence). A cursor that fell behind the 1024-item retention window is
flagged through the existing truncated signal together with minSeq so
the client can restart from it. Sequencing survives task completion:
the completion archive stores the seq-stamped window. None keeps the
exact legacy full-snapshot behavior, so existing clients see no change.
Typed overlap handling for admin starts: RUSTFS_HEAL_OVERLAP_POLICY
(merge default | minio_error). Under minio_error, an admin start whose
path overlaps an active or queued task rejects with typed
already-running / overlapping-paths admission reasons (surfaced through
reason_label in the admin error body, sharing the existing
OperationAborted site because the s3s footprint ratchet forbids new
s3_error! sites); an exact duplicate start rejects with
already-running instead of silently merging. Scanner/autoheal/
read-repair sources never take the rejection path.
forceStart semantics now match MinIO for admin requests: an admin
forceStart first cancels the overlapping active admin task, then
admits the replacement.
Wire: the heal-control Query command grows an optional sinceSeq
(defaulted and skipped when absent, so older peers stay compatible);
the admin handler accepts the sinceSeq query parameter; the local
channel query gains the same cursor.
Tests: seq monotonicity and incremental slicing, window slide moving
minSeq with lagging-cursor flags, overlap matrix (same/containing/
contained/disjoint x policy x source), forceStart cancel-then-admit,
and the completion-archive window handoff.

* feat(common): add MRF intent channel and Mrf request source (HS-01)
Introduce the producer-facing half of the mission repair feed: a global
bounded (8192) channel carrying lightweight MrfIntent values from IO
error paths, plus the RUSTFS_HEAL_MRF_ENABLE delivery kill-switch and
config constants for queue/journal sizing. Delivery is strictly
non-blocking (try_send, drop-on-full) so it can sit on decode-failure
and partial-write paths without adding latency. HealRequestSource grows
a 'mrf' variant so admission accounting can attribute replayed intents.

durable retry ledger).

* feat(heal): add MRF queue, durable journal, and intent consumer (HS-01)
Consumer half of the mission repair feed: a bounded pending queue
(100k intents / 8 MiB dual ceiling, drop-newest on overflow), a durable
journal at buckets/.heal/mrf/journal.bin holding the unaccepted pending
snapshot, and a consumer task that batches intents off the global
channel, translates them into prioritized heal requests (decode
failure -> Urgent ECDecode, metadata corruption -> High Metadata,
partial write -> Normal object heal), and retries full admissions with
a 5s backoff and a 3-attempt ceiling.
Durability: every journal record carries its own CRC32 and a
format/version header, so a torn tail truncates cleanly at replay; the
journal is deleted after a successful replay and when the pending set
drains (mirroring MinIO's post-replay list.bin unlink). Losing the last
500 ms flush window is acceptable: replayed duplicates merge via the
manager dedup key and read-repair remains the safety net.
Metrics: rustfs_heal_mrf_queue_depth/_queue_bytes, _dropped_total
{reason}, _replayed_total, _journal_bytes, _journal_fsync_total.
The consumer is wired at heal runtime bootstrap right after manager
start, honoring RUSTFS_HEAL_MRF_ENABLE (default on, rollback = off).
Tests: unit tests for the dual ceiling, record roundtrip, torn-tail
truncation, and the priority mapping; integration tests against a real
4-disk ECStore proving channel intents reach the manager queue as
Urgent/mrf-attributed requests and journal replay arms intents, drops
torn tails, and removes the file.

* feat(ecstore,scanner): deliver MRF intents from error paths (HS-01)
Wire the three production delivery points, each a single non-blocking
try_send next to the existing in-memory heal paths, which stay as the
fast path:
- read.rs decode-error branch: DecodeFailure intent beside the existing
read-repair submit, so an Urgent ECDecode request survives restarts
even when the Low-priority read-repair request was dropped or lost.
- add_partial: PartialWrite intent, giving partial-write recovery a
durable Normal-priority object heal across restarts.
- scanner_folder metadata-corruption classification: MetadataCorruption
intent beside the existing High-priority scanner heal request.
All three are on error paths only: zero cost on healthy IO.

heal::Error carried six variants with zero construction and zero match sites (ConfigurationError, NotFound, TaskAlreadyExists, ManagerNotRunning, EventProcessingFailed, ProgressTrackingFailed) plus IO(String), which was never constructed either — its only appearances were two or-pattern match arms that could never fire (task.rs's demotion match and the recoverability classifier). All seven are deleted and the two or-patterns lose their dead alternative.
Config(String) stays (live, four construction sites); Io(std::io::Error) stays; the retry classifier's behavior is untouched per the issue constraint — removing an arm that can never match is not a classification change.

fix(heal): demote per-object logs and cap erasure-set failure warns
Follow-up to rustfs/rustfs#5716. Per-object heal task kinds (Object/Metadata/MRF/ECDecode) queued by MRF/autoheal/scanner loops emitted info!/warn!/error! lines per object: task lifecycle (started/completed/timed_out/failed), the missing-object warn, queue admission full/drop/displacement warns, retry-admission decisions, and uncapped per-object warns in erasure-set sweeps.
Add a shared demote_to_debug_when! macro that keeps aggregate task kinds and admin/internal requests at operator-visible levels while demoting per-object occurrences to debug!, sample-cap the erasure-set transient_skip/failed warns per bucket via take_failure_log_sample (reusing the heal_bucket_objects precedent), demote the per-retry admission decision logs to debug! (covered by rustfs_heal_admission_total and the scheduler task_retrying/task_failed events), and record the previously unmetered duplicate-admission outcome.

`test_heal_resume_across_page_boundary_e2e` panicked whenever the
erasure-set healer deferred a single object version to a later heal
cycle. Under load a per-version `heal_object` can hit a transient error;
`ErasureSetHealer::heal_bucket_with_resume` then persists its
resume/checkpoint state and returns a terminal `Failed { .. "retry
scheduled" }`, expecting a fresh heal run to finish the job. In
production the background scanner is that next run — the e2e had no such
follow-up, so the first task's `Failed` state failed the test. This is a
pre-existing rare flake (the wiped-disk heal is otherwise correct); it is
unrelated to any policy/proptest work that happened to surface it in CI.
Drive the heal to a genuine `Completed` instead: on a `Failed` carrying
the `retry scheduled` marker (retry budget still remaining) re-submit the
idempotent heal (`force_start`), mirroring the production scanner, up to a
small bound. A `Failed` without that marker (e.g. `exhausted retries`) or
any other non-`Completed` terminal state still fails the test, and the
strict per-version data-restoration assertions still run only after a
real `Completed`. `wait_for_task` is refactored onto the shared
`await_terminal_status` poller; its panic-on-failure semantics for the
unversioned-bucket heal are unchanged.
Test-only change; no production heal code is touched.

* test(utils): add rustfs-test-utils crate, absorb heal/iam ECStore bootstrap
backlog#1153 infra-1. The ~50-line "build a real temp-disk ECStore"
bootstrap was copy-pasted (and drifting) across the heal and iam
integration tests. This adds crates/test-utils (rustfs-test-utils, a
dev-dependency-only crate) owning that bootstrap and converts the four
copies into thin wrappers:
- TestECStoreEnvBuilder: disk_count (default 4), prefix (uuid-suffixed
/tmp dir), base_dir (caller-owned dir, e.g. tempfile::TempDir),
init_bucket_metadata (default true; the iam bootstrap test opts out
to preserve its historical semantics). TestECStoreEnv exposes
temp_root/disk_paths/ecstore plus a versioned-bucket helper, and
init_tracing() replaces the per-file Once blocks.
- All rustfs_ecstore imports stay behind src/ecstore_test_compat.rs,
the sanctioned test-compat boundary pattern (mirrors
crates/iam/tests/ecstore_test_compat).
- heal: heal_integration_test / heal_b5_versioned_regression_test /
heal_b920_subquorum_union_test drop their setup_test_env{,_n} copies
for heal_env{,_n} wrappers; the tests/storage_api.rs integration
surface shrinks to what test bodies still touch.
- iam: iam_bootstrap_no_lock_test drops build_local_ecstore; its
ecstore_test_compat fixture shrinks to SetupType +
update_erasure_type.
rg 'async fn setup_test_env' crates/heal crates/iam now returns 0.
Scanner's lifecycle tests are deliberately NOT absorbed (gated on
ilm-1; 14 of 15 are #[ignore]d today). Net -230 lines.
* fix(heal): drop tokio::fs import orphaned by the b920 bootstrap move
* fix(heal): drop tokio::fs import orphaned by the b5 bootstrap move
PR #4356 wired `reclaim_orphan_data_dirs` only into `heal_object`'s
post-heal tail, which runs after the `disks_to_heal_count == 0` early
return. That early return is exactly the state of the objects the sweep
targets: a valid `xl.meta` with all shards present plus a leaked
pre-#3510 data dir needs no shard healing, so a healthy heal returned
before reclaim and swept nothing. On a healthy deployment (single node,
no degraded disks) the reclaim was therefore dead code — an admin heal
walked the objects, "healed" them, and reclaimed no leaked space.
Run the best-effort reclaim on the `disks_to_heal_count == 0` path as
well, gated on `!opts.dry_run`. The shared match+log block is factored
into `reclaim_orphan_data_dirs_best_effort` so both exits behave
identically. A reclaim failure still never fails the heal.
Adds an end-to-end regression: put a healthy non-inline object, plant an
unreferenced UUID data dir under it on every disk that holds the object,
then drive `heal_object`. A dry-run heal must leave the stray in place; a
real heal must reclaim it while preserving the live data dirs, `xl.meta`,
and object contents. The test fails against the pre-fix control flow.

B5 switched heal enumeration to list_object_versions, which only reflects the
read-quorum metadata view: a version present on fewer than read-quorum disks was
never enumerated, so it was never healed. Add a per-erasure-set disk-walk UNION
enumerator (mirrors MinIO global-heal.go objQuorum=1 listPathRaw +
mergeXLV2Versions) that surfaces every (object, version) present on ANY disk and
feeds each to the existing per-version heal_object.
- filemeta: MetaCacheEntries::resolve_union (dir_quorum=1/obj_quorum=1) yields the
cross-disk version union at one tested seam.
- ecstore: SetDisks::heal_walk_versions_page (list_path_raw fan-out, min_disks=1,
dual object/version page bound, inclusive-forward de-overlap) + ECStore delegator
+ HealWalkVersion.
- ecstore data-safety guard: before dangling-delete, try_regenerate_recoverable_meta
physically probes part files via check_parts; when >= data_blocks data shards
survive (meta lost but data recoverable) it regenerates xl.meta from a surviving
FileInfo with the correct per-disk shard index instead of dangling-deleting.
Genuine torn writes (< data_blocks) keep the current behavior — no resurrection.
- heal: dw1: forward-marker cursor codec (reuses ResumeState.resume_cursor,
idempotent restart on foreign tokens); list_versions_for_heal_page_disk_walk
trait method (default falls back to the B5 read-quorum path); heal_bucket_with_resume
selects the disk-walk enumerator when scan_mode==Deep || source==AutoHeal, else
the unchanged B5 path; anti-loop guard aborts on (empty && truncated).

refactor(ecstore,heal): return the local disk map as an owned read guard (Phase 5 prep)
Prerequisite for the Phase 5 disk-registry migration (backlog#939): the disk
map cannot move from the process global into the per-instance InstanceContext
while callers depend on a `'static` read guard borrowed from the global.
Change `local_disk_map_read` to return an owned guard
(`OwnedRwLockReadGuard`) via `Arc::read_owned` instead of
`RwLockReadGuard<'static, _>`:
- ecstore `runtime::sources::local_disk_map_read` now returns
`OwnedRwLockReadGuard<..>` (holds an Arc clone of the lock), not a `'static`
borrow of `GLOBAL_LOCAL_DISK_MAP`.
- heal's forwarding accessor and its callers (which hold the guard across
`.await` while clearing/writing per-disk markers) keep identical behavior —
the owned guard derefs to the same map, so iteration is unchanged.
This decouples the heal crate from the global's `'static` lifetime so a later
PR can source the map from the current instance's context. Single-instance
behavior is byte-for-byte unchanged; the same read lock is held across the same
awaits.
Verification: cargo test -p rustfs-heal (201 tests green), cargo clippy -p
rustfs-ecstore -p rustfs-heal --all-targets (clean), make pre-commit (pass).
Refs: backlog#939 (Phase 5, disk-registry prerequisite)
The erasure-set finalize block only gated completion on failed_objects, so a pass with transient skips (unmet quorum, DiskNotFound, SlowDown, OperationCanceled) but zero hard failures was marked completed, its resume/checkpoint state cleaned up and the per-disk healing marker cleared. That violated the Transient invariant: the skipped versions were never re-healed on a later pass.
Broaden the finalize gate to failed_objects > 0 || skipped_objects > 0 and reuse the existing bounded-retry path (schedule_retry + checkpoint reset_for_retry, returning Err so the caller preserves state and keeps the healing markers). Transient conditions are deferred to the next heal cycle, never hot-retried in place.
Also fix the object/EC-decode heal success paths, which passed object_size as the failed positional arg to update_progress, corrupting objects_failed and the admin-visible success rate; pass 0 instead.
Add heal tests for the transient-skip finalize behavior and a progress test asserting a successful heal reports zero failures.

Disk-replacement heal previously repaired only the latest version of each
object and never enumerated objects whose latest version is a delete marker,
so old versions were left unrepaired on a replaced drive.
Switch heal enumeration from list_objects_v2 (latest-only) to
list_object_versions (every version incl. delete markers), thread the concrete
version_id into the existing per-version heal_object, and make resume
cursor-based instead of positional: an opaque (marker, version_marker) paging
token persisted in ResumeState, a length-prefixed injective per-version dedup
key, schema_version bumps (v2) migrated independently in each of the two
persisted files, and a retry that resets both managers together (fixing a
latent rescan-skips-everything defect). Adds a real-disk-wipe e2e regression
suite proving old versions and delete-marker-latest objects are physically
restored.

fix(heal): don't mark set healed / discard resume state when objects failed (backlog#855)
`execute_heal_with_resume` unconditionally called `mark_completed()` and
returned `Ok(())` after the bucket loop, even when objects failed. The caller
then treats `Ok` as success and cleans up the resume + checkpoint state, so a
heal run with per-object failures was reported as a clean completion and its
state (including the failed set) was destroyed with no retry.
Finalize based on the failure count instead:
- failed_objects == 0 -> mark completed (unchanged);
- failed_objects > 0 with retry budget left -> `schedule_retry()` (bump the
bounded retry counter + reset per-pass progress for a full re-scan) and
return Err, so `heal_erasure_set` preserves the resume/checkpoint state and
the caller keeps the healing markers for the next run;
- failed_objects > 0 with retries exhausted -> drop the resume state (no
zombie task) but still return Err so the markers survive for a later heal
cycle / the background scanner. Never silently claim a clean completion.
The failure identities are not persisted across pages (the per-page sets are
pruned in `complete_page`), so a retry is a bounded full re-scan; healed
objects are skipped quickly on the normal-scan pass.
Adds `ResumeState::reset_for_retry`, `ResumeManager::schedule_retry`,
`ResumeCheckpoint::reset_for_retry`, `CheckpointManager::reset_for_retry`, and
regression tests. This activates the failure path the caller already documents
at task.rs ("Keep the markers on failure ... the next run re-marks and
eventually clears them"), which was previously dead because heal never
returned Err on object failures.
Refs backlog#799 (B6).
fix(heal): classify heal_object errors by type, not "not found" substring (backlog#856)
The heal page loop classified heal_object errors with a substring test
(`message.contains("not found")`). `StorageError::DiskNotFound` renders as
"disk not found", so an offline drive during a deep-scan heal matched the
"object absent" branch: the object was returned as `Ok(false)`, recorded into
the checkpoint's processed set, counted as a success, and permanently skipped
on resume — the object silently never got healed.
Replace the substring test with a typed classifier over the wrapped
`StorageError`:
- genuine object/version absence (FileNotFound / FileVersionNotFound /
ObjectNotFound / VersionNotFound) -> Absent (treated as handled);
- transient infrastructure conditions (quorum errors, DiskNotFound,
VolumeNotFound, SlowDown, OperationCanceled) -> TransientSkip, so the object
is retried on a later pass instead of recorded as processed;
- everything else -> Failed (recorded as failed).
Deliberately does NOT use `StorageError::is_not_found()`, which lumps
DiskNotFound/VolumeNotFound with object absence — the exact conflation that
caused the bug. Applied to both the deep-scan and normal-scan heal_object call
sites. Adds regression tests for the classifier.
