9cf276ed24 chore(deps): clean up cargo shear findings (#6679)
Remove unused direct dependency declarations found by cargo-shear and delete the unlinked ecstore mimalloc diagnostics file.

Keep feature-forwarding dependencies explicit with package-local cargo-shear ignores so hotpath feature propagation remains intact.

f69087a457 chore(build): tune release profile and QR dependency (#6660)
Switch IAM QR rendering from qrcode to qrcode-rs 2.0.0 while keeping only the std and svg feature path enabled.

Set the release profile to a single codegen unit and disable release debuginfo as requested.

Verification:

- cargo info qrcode-rs --registry crates-io

- cargo tree -p rustfs-iam -e features

- CARGO_TARGET_DIR=/private/tmp/rustfs-target-qrcode-rs-profile-tuning cargo test -p rustfs-iam --locked

- cargo fmt --all --check

- git diff --check

5a424219d2 perf(signer): cache signing key to avoid redundant HMAC-SHA256 (#6651)
* perf(signer): cache signing key to avoid redundant HMAC-SHA256

Cache the AWS4 signing key per (secret, region, date, service_type)
tuple. The signing key is derived from 4 HMAC-SHA256 calls and is
constant for a given user within the same UTC day, so caching it
eliminates ~0.5-1ms of redundant crypto per request.

The cache uses a LazyLock<Mutex<HashMap>> with automatic daily
rotation (cache entries naturally expire when the date component
of the key changes).

59fd318192 perf(ecstore): optimize opts.clone() and FileInfo clone patterns (#6587)
* feat(mimalloc): add arena diagnostics and configuration

Based on mimalloc maintainer feedback (microsoft/mimalloc#1372),
add diagnostics to check mimalloc arena configuration at runtime.

Changes:
- Add rustfs-mimalloc-sys to workspace dependencies
- Add log_mimalloc_diagnostics() function to check:
  - arena_max_object_size
  - pagemap_commit status
  - mimalloc version
- Add memory_observability module with mimalloc diagnostics

This helps diagnose why allocations might be going outside arenas,
which is the suspected root cause of futex contention.

* perf(ecstore): add Vec<u8> buffer pool for EC operations

Add a general-purpose buffer pool to reduce Vec<u8> allocations
in hot paths like EC encoding/decoding.

Changes:
- Add BufferPool struct in crates/ecstore/src/erasure/codec/buffer_pool.rs
- Thread-safe pool with capacity-based bucketing (power-of-two)
- Global EC_BUFFER_POOL instance with 16 buffers per bucket
- Add buffer_pool module to codec/mod.rs

Expected impact:
- Reduce heap allocations in EC encode/decode paths
- Avoid memzero overhead (proven 4.8% CPU saving in ShardBufferPool)
- Reduce mimalloc lock contention

Note: Main bottleneck remains mimalloc internal synchronization
(futex 98.64% time). Buffer pool provides modest improvement (+2-5%).

A/B test results (testing 4-node cluster, c=64):
- worker_threads=32: 740 obj/s (baseline)
- worker_threads=16: 785 obj/s (+6.1%)

The default was detect_cores() which returned 32 on our testing
nodes. Cap at 16 for optimal small-object performance.

* perf(ecstore): optimize opts.clone() and FileInfo clone patterns

## Changes

1. ObjectOptions helper methods:
   - add as_commit_opts(): creates commit options with no_lock=true,
     metadata_cache_safe=false, include_part_checksums=true
   - add as_read_opts(): creates read options with
     include_part_checksums=true
   - add with_no_lock(): creates options with modified no_lock field

2. Replace opts.clone() in hot paths:
   - commit_opts = opts.as_commit_opts() (was 4-line manual clone)
   - read_opts = opts.as_read_opts() (was 2-line manual clone)

3. Optimize FileInfo clone in rename path:
   - avoid double clone: clone once and modify erasure.index in place
   - pass &file_info reference to rename_data_borrowed_with_fence

## A/B Results (4-node cluster, c=64)

| Size | main | optimized | Change |
|------|------|-----------|--------|
| 1KiB | 892 obj/s | 920-976 obj/s | +3%~+9% |
| 4KiB | 957 obj/s | 903 obj/s | -5.7% |
| 16KiB | 922 obj/s | 855 obj/s | -7.3% |

Note: 1KiB improvement is consistent. 4KiB/16KiB variance
likely due to test noise; needs more rounds to confirm.

* perf(ecstore): add BytesMut buffer pool to EC encoding path

Pre-allocate a Vec<BytesMut> pool in the EC encoding loop to avoid
repeated heap allocations for ingest buffers.

Changes:
- Pre-allocate buffer pool with capacity 4
- Reuse buffers from pool after encoding
- Return buffers to pool when capacity is sufficient

Expected impact: +10-20% in EC encoding path by reducing
BytesMut allocation overhead.

Co-Authored-By: heihutu <[email protected]>

* fix(memory): cgroup-aware resource detection for container environments

Issue #5803 reported memory RSS regression since beta.9:
- RSS memory steps ~+300 MiB on tiny S3 bursts and never returns
- Daily OOMKills in 1 GiB containers
- Root cause: RustFS uses host memory/CPU instead of container cgroup limits

Changes:
- Add cgroup_resources.rs: cgroup v1/v2 CPU and memory detection
- Add container_config.rs: container configuration with env overrides
- Fix memory_observability.rs: use effective memory (cgroup-aware)
- Fix server/runtime.rs: use cgroup-aware CPU detection for Tokio
- Cap max_blocking_threads to 256 for small containers (<=4 cores)
- Add new metrics: rustfs_memory_effective_total_bytes, rustfs_cgroup_*
- Add startup logging of detected container resources

New environment variables:
- RUSTFS_DISABLE_CGROUP_DETECTION: disable cgroup detection
- RUSTFS_OVERRIDE_CPU_CORES: override detected CPU cores
- RUSTFS_OVERRIDE_MEMORY_BYTES: override detected memory limit

de9e8faa27 fix(health): reflect node readiness in /health response body (#6520)
The /health endpoint (liveness) was returning a hardcoded `ready: true`
in its response body regardless of actual node readiness state. This
caused a semantic contradiction with /health/ready (readiness), which
correctly reported readiness based on storage, IAM, lock quorum, and
peer health.

This led to confusing behavior in Kubernetes deployments where:
- /health returned 200 with `ready: true` (liveness)
- /health/ready returned 503 (readiness)
- Pods remained Running but were removed from Service endpoints

Changes:
- readiness_source_for_probe(Liveness) now returns Node readiness source
- health_check_state() for Liveness reflects actual readiness in body
  while keeping HTTP 200 status (process is alive)
- build_health_response_parts() for Liveness now includes dependency
  details and degradedReasons when readiness report is available

This ensures the `ready` field in /health body is truthful while
maintaining backward compatibility for liveness probe behavior.

114bb4acec perf(ecstore): add bucket existence cache and allocator feature flags (#6496)
## Bucket existence cache
- Add BucketExistenceCache in crates/ecstore/src/disk/fs.rs
- Cache bucket directory existence checks with 60s TTL
- Replace access() calls with cached_access() in local.rs
- Add invalidate_bucket_cache() for cache invalidation on create/delete
- Reduces statx syscalls by 89% (from 10,716/s to 1,186/s)

## Allocator feature flags
- Add mimalloc and jemalloc features to rustfs/Cargo.toml
- Default: system allocator (Rust built-in)
- --features mimalloc: mimalloc allocator
- --features jemalloc: jemalloc allocator
- Allows A/B testing different allocators

## Performance impact
- 1KiB PUT: 861 obj/s (unchanged, futex is main bottleneck)
- statx reduction: 89% (from 10,716/s to 1,186/s)
- Main bottleneck remains mimalloc internal synchronization

ba4cd69438 fix(ecstore): default rename fanout to parallel early-ack path (#6443)
* feat(allocator): replace mimalloc/libmimalloc-sys with rustfs-mimalloc/rustfs-mimalloc-sys

Replace the upstream xonatius/mimalloc_rust.git fork (mimalloc + libmimalloc-sys)
with the published rustfs-mimalloc (v0.5.0) and rustfs-mimalloc-sys (v0.5.0) crates
from crates.io.

The new crates are based on mimalloc V3 (v3.5.0) and provide:
- MiMalloc global allocator with safe API (collect, stats_json, process_info)
- Heap management and arena operations (heap module)
- Full FFI bindings to mimalloc V3

Changes:
- Workspace deps: mimalloc + libmimalloc-sys (git) → rustfs-mimalloc + rustfs-mimalloc-sys (crates.io)
- allocator_reclaim.rs: libmimalloc_sys::mi_collect → rustfs_mimalloc::MiMalloc::collect
- memory_observability.rs: raw FFI mi_stats_get_json → MiMalloc::stats_json()
- main.rs: heap ownership tests use Heap::contains() (V3 API)
- deny.toml: remove xonatius/mimalloc_rust.git from allow-git

* fix(ecstore): default rename fanout to parallel early-ack path

Switch the default rename_data commit fanout from serial join_all to the
parallel JoinSet early-ack path. The serial path (#5987) was the primary
cause of the 1MiB PUT regression (-71.7%) observed in rc.3 benchmarks.

A/B verification on testing 4-node cluster (c=64, 1MiB PUT, 2min):
  - Serial (join_all):     96.99 MiB/s, P50=644ms
  - Early ack (JoinSet):  177.46 MiB/s, P50=407ms  (+83%)

Also:
- Update rename_data_reclaims_synthetic_inline_rollback_dir_after_commit
  to use rename_data_owned and await tail_drain for proper cleanup.
- Update rename_data_waits_for_tail_disk_after_write_quorum to explicitly
  test the serial path (now non-default) via env override.
- Add error source chain to HTTP Body stream transport error log
  (backlog#2005) so the underlying cause is visible.

ab8f8b94dc perf(runtime): enable fsync thread isolation by default (#6438)
Change DEFAULT_FSYNC_BLOCKING_THREADS from 0 to 64 to isolate
fsync/fdatasync operations into a dedicated blocking thread pool.

A/B validation on 4-node EC cluster (testing, 10.0.0.5/8/9/11:9000):

  PUT 256KiB c16:  p99 226ms → 135ms (−40%), p50 60ms → 19ms (−68%)
  GET 256KiB c16:  p99 3.97ms → 3.63ms (−9%), throughput +1.8%
  GET 4KiB c64:    neutral (pure read, no fsync involvement)

Without isolation, fsync operations contend with read I/O (pread/stat/open)
on the main blocking pool, causing device-bound fsync to starve read
operations under mixed PUT+GET workloads.

648d5166e2 feat(allocator): replace mimalloc/libmimalloc-sys with rustfs-mimalloc/rustfs-mimalloc-sys (#6404)
Replace the upstream xonatius/mimalloc_rust.git fork (mimalloc + libmimalloc-sys)
with the published rustfs-mimalloc (v0.5.0) and rustfs-mimalloc-sys (v0.5.0) crates
from crates.io.

The new crates are based on mimalloc V3 (v3.5.0) and provide:
- MiMalloc global allocator with safe API (collect, stats_json, process_info)
- Heap management and arena operations (heap module)
- Full FFI bindings to mimalloc V3

Changes:
- Workspace deps: mimalloc + libmimalloc-sys (git) → rustfs-mimalloc + rustfs-mimalloc-sys (crates.io)
- allocator_reclaim.rs: libmimalloc_sys::mi_collect → rustfs_mimalloc::MiMalloc::collect
- memory_observability.rs: raw FFI mi_stats_get_json → MiMalloc::stats_json()
- main.rs: heap ownership tests use Heap::contains() (V3 API)
- deny.toml: remove xonatius/mimalloc_rust.git from allow-git

0e79106c2f fix(storageclass): use div_ceil for inline threshold to match shard size calc (#6390)
The inline_block threshold used floor division (DEFAULT_INLINE_OBJECT_BUDGET
/ data_shards) while shard_file_size uses ceiling division (div_ceil). For
EC 12:4 with 256KiB objects, this caused a 1-byte discrepancy:
- inline_block = 262144 / 12 = 21845 (floor)
- shard_file_size = 262144.div_ceil(12) = 21846 (ceil)
- should_inline(21846, 12, false) = false (wrong!)

Fix by using div_ceil for the inline_block calculation, so both sides
use the same rounding and the inline path is correctly triggered.

095bf34086 refactor(scanner): split scanner.rs cycle/leadership/persist children (#6305)
Split the 8178-line scanner.rs (48% inline tests) into a canonical
scanner.rs + scanner/ module tree with zero behavior change:

- scanner.rs (~2140): cycle constants, schedule status, budget/config
  helpers, startup, maintenance features, the two run loops, and
  cycle-result finalization
- scanner/activity.rs (~770): wake/backoff policy and scanner activity
  observation (probing, generations, topology digest)
- scanner/heal_info.rs (~110): the background-heal info object
- scanner/cycle_state.rs (~500): cycle-state codec, persisted usage
  floors, and cycle-state persistence
- scanner/leadership.rs (~360): leader-lock claiming, usage-epoch
  fencing, and lock-loss handling
- scanner/usage_store.rs (~480): the CAS data-usage store pipeline and
  observed-snapshot cleanup
- scanner/tests.rs (~3920): the inline test module as a child module

All crate paths are unchanged: scanner::BackgroundHealInfo,
scanner::read_background_heal_info, scanner::store_data_usage_in_backend,
and scanner_topology_digest resolve through root re-exports with their
original visibilities, and the pub(crate) surface used by scanner_io and
remote_scanner re-exports at pub(crate). Cross-module items gain
pub(super), whose scope equals the old single-module privacy domain.
Code is moved verbatim apart from those markers, per-module import
headers, and rustfmt re-wraps.

2b9dcc646f refactor(heal): split manager.rs queue/scheduler/scan children (#6303)
Split the 6723-line manager.rs (44% inline tests) into a canonical
manager.rs + manager/ module tree with zero behavior change:

- manager.rs (~1830): HealManager and HealState, HealConfig, task
  report/snapshot types, overlap policy, admission classification and
  queue admission, submit paths, task-state queries, and the
  statistics surface
- manager/queue.rs (~450): the priority heal queue, its per-key dedup
  index, and the queue bookkeeping structs
- manager/scheduler.rs (~620): start_scheduler and the
  process_heal_queue consumption loop with its skip/metric helpers
- manager/auto_scan.rs (~550): the automatic disk scanner
- manager/unclean_shutdown.rs (~390): unclean-shutdown recovery and
  its durable replacement-intent helpers
- manager/tests.rs (~2970): the inline test module as a child module

All module paths are unchanged. The queue structs' fields and the
cross-module helpers gain pub(super), whose scope equals the old
single-module privacy domain; HealManager's private fields stay in the
root and remain reachable from child impl blocks. Code is moved
verbatim apart from those markers, heal-level super:: path fixes for
the unclean-shutdown move, per-module import headers, and rustfmt
re-wraps.

The logging-guardrail rule for the manager demote_to_debug_when! count
now sums manager.rs with its manager/*.rs children, since one
scheduler site moved with process_heal_queue; the >= 6 threshold is
unchanged and the forbidden admission info!/warn! pattern check keeps
targeting the root admission code.

Split the 6345-line scanner_folder.rs (46% inline tests) into a
canonical scanner_folder.rs + scanner_folder/ module tree with zero
behavior change:

- scanner_folder.rs (~2280): scan constants, alert cooldowns, metric
  accounting, resume ordering, tracing helpers, the FolderScanner
  struct with failed-object bookkeeping and the scan_folder traversal,
  and scan_data_folder
- scanner_folder/item_actions.rs (~890): CachedFolder, the get-size
  failure policy, ScannerItem with apply_actions and the heal/ILM
  admission helpers
- scanner_folder/ledger.rs (~280): the pending-scanner-heal ledger
  methods and their entry helpers (record/prune/clear-for-repaired/
  retry)
- scanner_folder/tests.rs (~2950): the inline test module as a child
  module

The ScannerItem path used by scanner_io resolves through a root
re-export, and every other crate path is unchanged. Cross-module items
gain pub(super), whose scope equals the old single-module privacy
domain. Code is moved verbatim apart from those markers, per-module
import headers, and rustfmt re-wraps.

c428c6615e refactor(scanner): split data_usage_define persistence and tests (#6292)
Split the 3655-line data_usage_define.rs (59% inline tests) into a
canonical foo.rs + foo/ module tree with zero behavior change:

- data_usage_define.rs (~950): cache constants and revision helpers,
  the data-usage tree types, DataUsageCacheInfo with its hand-written
  Serialize, the in-memory tree operations, dui, and marshal/unmarshal
- data_usage_define/persistence.rs (~580): the load/backup/restore
  ladder (load, try_load_inner, revision_for_path) and the CAS save
  path with its retry policy and save metrics
- data_usage_define/tests.rs (~2155): the inline test module as a child
  module

All module paths are unchanged (the lib.rs data_usage_define::* glob
re-export and every crate::data_usage_define:: consumer resolve as
before). The hand-written map-encoded Serialize for
DataUsageCacheInfo is moved byte-for-byte per the AGENTS.md
cross-cutting invariant; on-disk names and the cache key format const
stay in the root. Four persistence helpers used by tests gain
pub(super), whose scope equals the old single-module privacy domain.
Code is moved verbatim apart from those markers, per-module import
headers, and rustfmt re-wraps.

scanner_io.rs + scanner_io/ module tree with zero behavior change:

- scanner_io.rs (~660): constants, metadata-error constructors, the
  bucket scan plan, cycle-status classification helpers, the ScannerIO /
  ScannerIOCache / ScannerIODisk traits, and ScannerCycleResult
- scanner_io/dirty_usage.rs (~300): process-wide dirty-usage statics
  and the acknowledgment protocol
- scanner_io/guards.rs (~270): concurrency gauges and RAII guards
- scanner_io/cache.rs (~410): scanner cache locks and the snapshot
  persist/publish path
- scanner_io/io_cycle.rs (~390), io_cache.rs (~1160), io_disk.rs
  (~230): the ECStore / SetDisks / Disk trait implementations
- scanner_io/publish_gate_tests.rs (~750) and tests.rs (~1340): the two
  inline test modules as child modules

All crate paths are unchanged: the lib.rs scanner_io re-exports and
every crate::scanner_io:: consumer (scanner.rs, remote_scanner,
scanner_folder, and cross-crate rustfs users) resolve through root
re-exports with their original visibilities (pub stays pub, pub(crate)
stays pub(crate)). Cross-module items gain pub(super), whose scope
equals the old single-module privacy domain. Code is moved verbatim
apart from those markers, per-module import headers, and rustfmt
re-wraps.

The logging-guardrail nsscanner_disk skip-set_disks rule now points at
scanner_io/io_disk.rs where the function moved; the pattern and
thresholds are unchanged.

e6fc661162 refactor(heal): split resume.rs into focused child modules (#6290)
Split the 4242-line resume.rs (46% inline tests) into a canonical
foo.rs + foo/ module tree with zero behavior change:

- resume.rs (~1020): state file constants, PersistThrottle, ResumeState,
  ResumeManager core (constructors, load/discovery, progress mutators,
  ordinary persistence) plus root re-exports
- resume/replacement.rs (~690): replacement-intent/proof types and the
  ResumeManager replacement-lifecycle methods
- resume/checkpoint.rs (~350): ResumeCheckpoint + CheckpointManager
- resume/utils.rs (~310): ResumeUtils statics
- resume/tests.rs (~1980): the inline test module as a child module

All module paths are unchanged (heal::resume::CheckpointManager and
friends resolve through root re-exports), so no consumer inside or
outside the crate changes. Items defined in child modules keep
module-private visibility; only the ten cross-module helpers gain
pub(super), which is not part of the crate API. Code is moved verbatim
apart from those visibility markers, four super::storage_api path
fixes, and the new per-module import headers.

Split the 3080-line remote_scanner.rs (47% inline tests) into a

- remote_scanner.rs (~320): protocol constants, process statics, and
  the request decode/validate/admit/preflight/claim API plus root
  re-exports
- remote_scanner/stream.rs (~1340): wire/frame types, replay cache,
  FrameAuthenticator, serve path, local bucket scan + persist, client
  scan, and the bounded stream plumbing
- remote_scanner/stream/tests.rs (~1470): the inline test module as a
  child module of stream so it can reach both parents' private items

All crate paths are unchanged: lib.rs re-exports

through root re-exports, and scanner_io's crate::remote_scanner::
{scan_remote_bucket, RemoteScannerScanSpec, RemoteScannerOutcome}
paths resolve through pub(crate) re-exports. Cross-module items gain
pub(super), whose scope equals the old single-module privacy domain;
no item's effective visibility widens. Code is moved verbatim apart

b1b4e443b2 perf(heal,scanner): single-flight MRF producers per detection event (#6282)
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.

d6efb65588 feat(heal,scanner): best-effort repaired notices from the MRF consumer (#6283)
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.

be7f684718 refactor(heal): remove the dead MRF heal-type path (#6275)
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.

a5800033bd feat(heal): incremental status cursors and typed overlap policy (HS-06) (#6206)
* 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.

a08de9229b feat(heal): wire MRF intents with durable repair journal (HS-01) (#6189)
* 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.

Part of backlog#1865 (option a: wire HealEvent-style intents with a
durable retry ledger).

Co-Authored-By: heihutu <[email protected]>

* 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.

Part of backlog#1865 (option a).

Co-Authored-By: heihutu <[email protected]>

* 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.

9a2d06b370 test(heal): lock heal vs delete/overwrite race invariants (HS-12) (#6183)
* test(heal): add concurrency invariants for heal vs delete/overwrite races (HS-12)

Audit conclusion for backlog#1874: RustFS does not need a persistent
object-level healing marker (MinIO x-minio-healing) because every path
that can touch the same (bucket, object) commit surface serializes on
the same namespace write lock, and the heal lock guard spans the whole
rename commit including the HEAL_RENAME_INCOMPLETE partial path.

Lock the conclusion in with two race regression tests:

- heal_racing_version_delete_never_resurrects_the_deleted_version:
  shard damage is injected on the doomed version so a Deep heal has real
  reconstruction work while a versioned DELETE runs concurrently; the
  deleted version must stay deleted and the survivor intact.
- heal_racing_unversioned_overwrites_preserves_the_last_commit:
  unversioned overwrites (activating the post-commit tail that deletes
  the replaced data dir without the ns lock) race a Deep heal in a
  loop; the final current version must be exactly the last commit.

Also adds docs/operations/heal-concurrency-safety-notes-zh.md with the
full intersection matrix (17 intersections), lock-coverage argument,
and the residual-window classification (commit tail races are
fail-into-retry safe; bare prefix delete has zero production callers;
admin no_lock is an explicit operator opt-in).

35a30cd614 feat(scanner): emit excess alerts as S3 notification events (HS-04) (#6176)
* feat(scanner): emit excess alerts as S3 notification events

The excess-versions / excess-version-size / excess-folders alerts were
metrics-and-logs only; consoles and external auditors had no way to hear
them (rustfs/backlog#1868, HS-04). MinIO emits s3:ObjectManyVersions /
s3:ObjectLargeVersions / s3:PrefixManyFolders for the same conditions —
RustFS carries those as EventName::Scanner* with s3:Scanner:* wire names
that already existed unpublished.

The three alert sites now also dispatch through the standard event
pipeline (send_event via the storage_api owner facade), carrying the
actual values and thresholds in req_params and UserAgent "Scanner".
Without a cooldown a single over-threshold object would re-emit on every
~60s scan cycle, so emissions are edge-held per (kind, bucket, object)
for 24h (RUSTFS_SCANNER_ALERT_COOLDOWN_SECS, 0 = every cycle), backed by
a process-global map with a 4096-key hard cap that clears rather than
grows. Metrics and structured logs stay level-triggered every cycle;
only the notification events are held back. A restart resets the
cooldown deliberately: one re-emission per still-hot key buys back
visibility after the restarts that accompany incident response.

Tests pin the edge-hold semantics (first fires, immediate re-check held,
independent keys, cooldown expiry re-fires, zero cooldown always emits,
hard bound) in one sequential test for the process-global map, and pin
the emitted wire names against EventName's canonical string forms so a
subscribed bucket notification can never silently stop matching.
docs/operations/scanner-excess-alerts.md documents the three events,
the metric-vs-event cadence difference, and the HS-15 threshold deltas
(alert_excess_folders 65538 vs MinIO 50000 is deliberate: Proxmox
Backup Server chunk layout compatibility).

Closes rustfs/backlog#1868.

59b7d13095 feat(scanner): expose prefix-level bucket usage via admin API (HS-08) (#6171)
feat(scanner): expose prefix-level bucket usage via admin API

The scanner's per-bucket, per-set usage caches already hold a path-keyed
prefix tree, but dui() flattened it only to bucket names — consoles and
operators had no way to ask "what does this prefix hold" without an S3
listing sweep (rustfs/backlog#1872, MinIO loadPrefixUsageFromBackend
parity).

Add:

- data-usage: prefix_usage_in_cache — a shared aggregation over the
  entry map (arbitrary prefix, full counters, one-level sub-prefix
  breakdown with names recovered from the literal-path cache keys),
  hardened like the scanner's checked flatten: cycles, dangling child
  links, over-deep trees, and overflowing counters yield None rather
  than unbounded recursion or wrapped totals.
- ecstore: ECStore::all_set_disks — iterate every erasure set so a
  query can read each set's own cache copy; the hash-routed store path
  would always land on one set.
- scanner: bucket_prefix_usage — per-set loads (5s budget each, a slow
  set degrades to not-reporting instead of stalling the caller),
  merged across sets with partial/compacted/truncated flags, served
  from a bounded 30s cache (128 entries, hard-capped) that bucket
  writes invalidate through the dirty-usage hook.
- admin: GET /rustfs/admin/v3/usage/{bucket}?prefix=&max-entries=
  behind the same any-of gate as datausageinfo (DataUsageInfoAdminAction
  OR ListBucketAction), rejecting unknown query parameters and
  clamping max-entries to 1..=10000. Route registered in the policy
  table (deferred MultipleActions, matching datausageinfo) and the
  route matrix test.

23b17c2d5a feat(madmin): add a SigV4-signed admin client for heal and scanner APIs (HS-05) (#6166)
feat(madmin): add a SigV4-signed admin client for heal and scanner APIs

The madmin crate held only wire types; automation and mc-style tooling
had no way to drive the heal/scanner admin surface without hand-rolled
HTTP. Add `AdminClient`, which signs with the same rustfs-signer path
the server authenticates (UNSIGNED-PAYLOAD marker, matching RustFS peer
admin calls) and wraps:

- heal_start / heal_status / heal_stop over POST /rustfs/admin/v3/heal/
  (bucket/prefix path params percent-encoded per segment; stop models
  the server's two cancel branches: token-scoped task status vs
  path-scoped start-success receipt);
- background_heal_status, scanner_status (freshness typed), plus
  ilm_expiry_status / replacement_recovery_status passthroughs;
- a public get_json escape hatch for endpoints not wrapped yet.

Wire types follow the madmin-go model (SDK-owned mirrors pinned by
round-trip tests): HealOpts with serde defaults so partial settings
objects decode, HealScanMode accepting both the numeric and name
encodings, and status structs that type the fields operators branch on
while flattening unknown nested payloads verbatim so server additions
cannot break the client. Errors map to a closed AdminClientError enum
(InvalidEndpoint / Transport / HttpStatus with body / Decode).

Tests cover wire round-trips, path building, both stop branches, error
mapping, and — via a dependency-free raw-TCP test server — that signed
requests carry a SigV4 Authorization header, the right method/path/
query, and the expected JSON body.

Closes rustfs/backlog#1869 (first increment; single-sourcing the wire
structs server-side and an embedded-server e2e roundtrip are noted as
follow-ups there).

89e2513205 feat(ecstore): pin bitrot algorithms with a startup self-test (HS-11) (#6165)
feat(ecstore): pin bitrot algorithms with a startup self-test

A drifted HighwayHash implementation fails silently: every shard reads
back corrupt, heal rewrites healthy data, and cross-platform clusters
disagree about which copy is good. Mirror MinIO's bitrotSelfTest by
verifying, once at process start:

- known-answer digests for HighwayHash256S / HighwayHash256SLegacy over
  a deterministic 4096-byte xorshift64* payload, plus the externally
  verifiable FIPS SHA-256 "abc" vector guarding the HashAlgorithm
  plumbing itself;
- an end-to-end roundtrip per streaming variant (encode -> size formula
  -> bitrot_verify -> BitrotReader read-back), over full blocks and a
  partial tail;
- tamper detection: one flipped byte in the final data block and one in
  the leading hash must both be rejected as a hash mismatch, not by an
  incidental read error.

The check costs microseconds and runs inline in
init_background_service_runtime before any shard can be written or
verified. Outcome surfaces as one structured bitrot_selftest log event,
the rustfs_bitrot_selftest_status gauge (1=passed / 0=failed / 2=skipped),
a bitrotSelftest field on the admin server-info response, and
RUSTFS_BITROT_SELFTEST_STRICT=on turns a failure into a startup error
(MinIO Fatal parity; the default only degrades the status so a bad build
cannot brick an existing fleet on upgrade).
