* feat(ecstore): reclaim orphaned data dirs during heal (backlog #3231/#3191)
Pre-#3510, an unversioned overwrite leaked one UUID-named data dir per PUT.
The write path now cleans up going forward, but pre-existing strays stay on
disk forever: heal's dangling logic only removes whole objects whose data is
missing, never surplus data dirs of an otherwise-healthy object. That leaked
space is what eventually made ListObjects scan tens of GB and time out.
Add SetDisks::reclaim_orphan_data_dirs, a fail-closed, quorum-safe sweep that
mirrors purge_orphan_dir_object:
- referenced set is the UNION of get_data_dirs() across every online replica's
xl.meta, so a dir named by any replica is kept;
- if a disk holds the object dir but its xl.meta is missing or unparseable the
object is treated as degraded and nothing is removed;
- only UUID-named subdirectories are ever considered.
Wire it into heal_object's healthy tail (under the object write lock) as a
best-effort step so the background heal scanner and admin heal recover the
leaked space automatically; a reclaim failure never fails the heal.
Covered by four unit tests: removal of an unreferenced dir, no-op when all dirs
are referenced, fail-closed abort on missing metadata, and cross-replica union
preservation.

* fix(ecstore): fsync inline rename_data rollback backup
The inline branch of LocalDisk::rename_data writes the previous version's
xl.meta rollback backup (<old_data_dir>/xl.meta.bkp) with a bare
std::fs::write, fsyncing neither the file nor its new directory entry, even
when drive_sync_enabled() is true. The same closure already syncs the new
xl.meta and the commit rename directory, and the non-inline branch persists
its backup durably.
That backup is the sole restore source for delete_version(undo_write=true)
on a set-level write-quorum failure. With sync enabled, an inline overwrite
plus power loss plus a quorum failure that triggers undo_write could restore
a lost or truncated backup and fail to roll back to the prior committed
object.
Write the inline backup via OpenOptions + write_all and, when sync is
enabled, sync_data() it and fsync_dir_std its parent, mirroring the
non-inline branch. Extend the inline backup test to assert the .bkp contents
equal the previous metadata bytes.
Refs backlog#868 (disk-durability-01).
* fix(ecstore): preserve to_file_error mapping on inline backup write
Address review: the rewritten inline rollback-backup write must keep the
same DiskError classification as the previous std::fs::write(...).map_err(
to_file_error)? call. Without it, io errors (PermissionDenied/NotFound/
StorageFull/...) would surface as DiskError::Io(_) instead of the specific
DiskError variants (FileAccessDenied/FileNotFound/DiskFull/...), since
From<io::Error> for DiskError only recovers variants that were wrapped via
to_file_error. Map open/write_all/sync_data/fsync_dir_std through
to_file_error, matching write_all_internal.

The xl.meta version header `signature` was hardcoded to `[0,0,0,0]` on the
write path (`From<FileMetaVersion> for FileMetaVersionHeader`), and the
existing `get_signature` implementations only hashed `version_id` + `mod_time`
(+ `size`), so two versions that share a version_id and mod_time but differ in
body (e.g. a PutObjectTagging that reached only some disks) produced identical
headers. Such divergence was undetectable and unhealable in the strict merge
path (backlog#861, B12).
Compute a real signature over the full version body, mirroring MinIO's
`xlMetaV2Version.getSignature` semantics:
- Fill the signature on the write path via the `From` impl (covers
add_version / set_idx / update_object_version).
- `MetaObject::get_signature` / `MetaDeleteMarker::get_signature` now clone the
body, zero the per-disk `erasure_index`, fold `meta_user` / `meta_sys` in
with order-independent hashes (msgpack map order is not stable across disks),
marshal the rest and xxh64 it, then fold 64->32 bits. Empty vs all-empty
PartETags are normalized alike.
- Invalid/bodyless versions return an `err` sentinel rather than all-zero, so
they never collide with a real all-zero legacy signature.
Backward compatibility: the decode path preserves stored signature bytes, and
the normal (non-strict) merge path already zeroes signatures before grouping,
so existing all-zero xl.meta stays consistent across disks. Only strict
merge/heal compares signatures, where legacy data is uniformly zero (no split)
and genuine partial-write divergence is now correctly detected.
Adds unit tests covering: non-zero signature on write, erasure_index
independence, tag/metadata/size divergence detection, map-order independence,
PartETags normalization, delete-marker divergence, and the err sentinel.
* fix(ecstore): make delete_volume non-recursive by default to prevent bucket-heal wipe (backlog#799 B1)
`delete_volume` unconditionally `remove_dir_all`'d the whole bucket tree, and the
bucket-heal "remove" branch called it fire-and-forget on every local disk. A
mis-classified "dangling" bucket (or a non-force S3 DeleteBucket on a populated
bucket) was therefore recursively wiped — a potential whole-bucket data loss.
The `VolumeNotEmpty` -> recreate/`BucketNotEmpty` handling already present in
both delete_bucket paths was dead code because the primitive never refused.
Add an explicit `force_delete` flag to `DiskAPI::delete_volume` and default the
non-force path to a non-recursive `remove_dir` (rmdir), which fails atomically
with `VolumeNotEmpty` if the bucket still holds any object data. Only an explicit
force delete (S3 force bucket delete) removes recursively. Mirrors MinIO's
`xlStorage.DeleteVol` (`Remove` vs `RemoveAll`).
- Trait + all impls (local behavior, dispatch, disk_store, remote RPC) take the
flag; the gRPC `DeleteVolumeRequest` gains a `force` field (proto3 default
false → old peers get the safe non-recursive behavior on rolling upgrade).
- Heal remove branch passes `false` and no longer discards the result: a
`VolumeNotEmpty` refusal is logged (the bucket is not dangling) instead of
wiping data.
- Both `delete_bucket` paths pass `opts.force`, activating the previously-dead
`VolumeNotEmpty` -> `BucketNotEmpty`/recreate handling (correct S3 semantics).
Adds a regression test: non-force delete of a non-empty bucket returns
VolumeNotEmpty and preserves the data; force delete removes it.
Design converged by two independent expert reviews (MinIO-fidelity +
defense-in-depth) referencing MinIO xl-storage.go. Refs backlog#799 (B1),
issue rustfs/backlog#850. The safety expert's deeper hardening (typed
capability instead of a bool, trash-instead-of-in-place for force, quorum
re-verification of dangling) is noted on #850 as follow-up.

fix(filemeta): resolve P2 core-storage audit items B15/B16/B18 (backlog#863)
Fixes the three remaining actionable items from the core-storage reliability
audit (rustfs/backlog#863). All three are metadata-layer correctness defects in
the filemeta crate.
B15 — version sort tie-break consistency
`FileMeta::sort_by_mod_time` and the delete path used a hand-rolled comparator
whose version_type tie-break for equal mod_time was the OPPOSITE of the
canonical `FileMetaVersionHeader::sorts_before` (used by the metacache merge
and latest-version selection). At equal mod_time it sorted a delete marker
before its object, so the per-disk read path could treat an object as deleted
while the quorum-merge path treated it as present. Both sort sites now derive
their ordering from `sorts_before`, matching MinIO (object-first).
B16 — replication reset state persistence
The three sites that flush `reset_statuses_map` into `meta_sys` inserted each
key verbatim. A bare-ARN key (produced by `ObjectInfo::replication_state`) has
no internal prefix, so read-back — which only recognizes prefixed keys —
silently dropped the reset state; a rustfs-only key was invisible to
MinIO-compatible readers. New `persist_reset_statuses` normalizes every entry
to the canonical `replication-reset-<arn>` suffix and writes both the
`x-rustfs-internal-*` and `x-minio-internal-*` prefixes.
B18 — Legacy (V1Obj) body round trip
`FileMetaVersion::encode_to` never emitted the `V1Obj` field, so re-encoding a
Legacy version silently dropped its entire body. Adds symmetric `encode_to`
for `MetaObjectV1`/Stat/Erasure/ChecksumInfo/Part and a `write_msgp_time`
helper (ext8/type-5/12-byte, matching the decoder). `Mode` uses the strict
`write_u32` marker the decoder requires, and `Stat.ModTime` is written only
when present so a `None` never round-trips to `Some(UNIX_EPOCH)`.
Adds regression tests for each fix (138 filemeta tests pass). Verified with an
adversarial multi-expert review that could not break any of the three.
Refs rustfs/backlog#863 (B15, B16, B18).
The codec streaming GET reader divides by erasure.block_size in
build_codec_streaming_part_reader without validating the erasure
dimensions, unlike the legacy multipart path which already rejects
block_size==0 / data_shards==0. FileInfo::is_valid() does not check
block_size, so corrupted on-disk metadata (block_size==0, data_blocks>0)
passes validation and panics the read task with a divide-by-zero.
Add Erasure::has_valid_dimensions() and reject invalid dimensions at the
codec streaming entry before any disk access, mirroring the legacy guard
(which now reuses the same predicate).

* feat(internode): P0 gRPC transport tuning, message limits, payload metrics
Land the P0 subtask from docs/grpc-optimization: close the client-vs-server
transport gaps and add instrumentation to size which unary RPCs need channel
isolation in P1.
Transport tuning (G3): the client `Endpoint` now disables Nagle and raises the
HTTP/2 stream/connection flow-control windows to mirror the server socket, so
small lock/health RPCs are not batched and larger metadata responses are not
throttled by the 64KiB default window. All env-overridable, 0 opts out.
Message-size limits (G1): both `NodeServiceClient` and `NodeServiceServer` set
max decode/encode size (default 100MiB) instead of tonic's silent 4MiB cap, so a
large multi-version xl.meta or aggregated ReadMultiple no longer fails
out_of_range. The server limit is set on `NodeServiceServer` before wrapping in
the auth `InterceptedService` (the interceptor type does not expose it).
Payload instrumentation (P1 prep): ReadAll/ReadMultiple record a payload-size
histogram plus a large-payload counter when a response crosses the configured
threshold (default 8MiB), feeding alerting on paths that contend with
latency-sensitive control-plane traffic on the shared channel. Threshold-only
counter, no per-call hot-path log.
Verification: cargo check/test on config, io-metrics, ecstore, rustfs; clippy
clean on touched files; make pre-commit green.

* feat(internode): P1 control/bulk gRPC channel isolation (opt-in)
Land the P1 subtask from docs/grpc-optimization: physically separate large
bytes-carrying unary RPCs from latency-sensitive control-plane RPCs so a big
transfer can no longer head-of-line block a lock/health RPC on the shared
HTTP/2 connection (G2/G5).
Introduce ChannelClass { Control, Bulk } and get_channel_for_class in protos.
Control RPCs keep the per-peer connection keyed by the bare address; Bulk RPCs
(ReadAll/WriteAll/ReadMultiple/BatchReadVersion, via a new get_bulk_client) are
round-robined across a small per-peer bulk pool.
Rather than restructuring the global GLOBAL_CONN_MAP (and every consumer), bulk
channels are cached under a composite key (addr\0bulk\0idx). The NUL separator
cannot appear in a URL, so bulk keys never collide with the control key. This
keeps the blast radius small on a consistency-sensitive path. create_new_channel
is refactored into build_channel(dial_addr, cache_key) so several physically
distinct channels to one peer cache independently while dialing/TLS still use
the real address.
Gated by RUSTFS_INTERNODE_CHANNEL_ISOLATION (default OFF) so the default build
is byte-for-byte the pre-P1 behavior: bulk resolves to the control channel and
the switch is a single-env rollback. RUSTFS_INTERNODE_BULK_CHANNELS (default 2,
clamped >=1) sizes the pool. On failure, evict_failed_connection drops the whole
bulk pool for the peer (round-robin hides which index was used), avoiding
half-dead cached channels.
Lock RPCs (remote_locker) already use the default Control path, so lock
semantics and retry behavior are unchanged.
Verification: cargo check/test on config, protos, ecstore, rustfs; new protos
tests for bulk key routing and isolation-off passthrough; clippy clean on
touched files; make pre-commit green.

* feat(internode): P2 msgpack/JSON codec observability + encode buffer presizing
Land the safe, wire-compatible slice of P2 from docs/grpc-optimization: the
observability prerequisite for retiring the redundant JSON fields, plus a codec
micro-optimization. No proto/wire-format change; JSON is still dual-written.
Internode RPCs today dual-encode each metadata value as both msgpack (`*_bin`)
and a JSON compatibility string, and decoders prefer `_bin` with a JSON
fallback. Before the JSON fields can ever be dropped (a cross-version change),
that fallback must be proven unused in production.
Add rustfs_system_network_internode_msgpack_json_fallback_total{direction,
message}: incremented whenever a decode falls back to the JSON field because the
msgpack payload was absent. Wired into both directions — the client decoding
peer responses (remote_disk.rs, incl. the list-level read_multiple/batch
fallbacks) and the server decoding peer requests (node_service/disk.rs). This
counter must read zero across a release window before send paths stop writing
JSON and the proto text fields are reserved/removed (the deferred P2-1 steps).
Also pre-size the msgpack encode buffers (Vec::with_capacity(512)) on both
sides, eliminating the repeated growth reallocations for typical FileInfo
payloads with zero added copy. Full thread_local buffer pooling is deferred: it
needs either an extra copy (unclear net win) or a send-path buffer-return
lifecycle, to be justified by a codec microbenchmark first.
Verification: cargo check/test on io-metrics, ecstore, rustfs; new fallback
counter smoke test; existing codec decode tests green; clippy clean on touched
files; make pre-commit green.

* docs(internode): add msgpack/JSON convergence observation runbook
Runbook driving the observation-gated retirement of the redundant JSON
compatibility fields on internode gRPC metadata RPCs (grpc-optimization P2-1).
Documents the shipped fallback counter
(rustfs_system_network_internode_msgpack_json_fallback_total{direction,message}),
the PromQL to confirm it reads zero across a release window, a standing alert,
and the staged flip/rollback procedure (env-gated msgpack-only send, then proto
field removal in N+1).
Includes the verified field -> peer-decoder audit: only fields whose peer
decodes _bin first may be converged. Notes DeleteVersion.opts (DeleteOptions) is
NOT convergence-ready — its server handler is not _bin-first and must gain a
decode_msgpack_or_json path first. This gates the send-side change so it cannot
empty a JSON field an old peer still needs.
Co-Authored-By: heihutu <heihutu@gmail.com>
* feat(internode): env-gated msgpack-only send + DeleteVersion _bin support (P2-1)
Implements the send-side lever for retiring the redundant JSON compatibility
fields on internode gRPC metadata RPCs, plus the missing `_bin` support on the
delete path that it depends on (grpc-optimization P2-1). Default-off: the base
build is byte-for-byte the prior dual-write behavior.
Gated msgpack-only send (RUSTFS_INTERNODE_RPC_MSGPACK_ONLY, default false):
- New rustfs_protos::internode_rpc_msgpack_only() reads the flag.
- Client (remote_disk.rs) compat_json() and server (node_service/disk.rs)
compat_response_json() emit an empty JSON string when the flag is on, so only
the msgpack _bin payload is sent. The _bin field is always sent; decoders keep
the JSON read fallback. Applied only to fields with a confirmed _bin-first peer
decoder (WriteMetadata/UpdateMetadata/RenameData file_info, UpdateMetadata opts,
ReadOptions, ReadMultipleReq, BatchReadVersionReq; ReadVersion/ReadXL/RenameData
responses and the ReadMultiple/BatchReadVersion response lists).
- Only enable after the P2 fallback counter has read zero across a release window
(see docs/operations/internode-msgpack-json-convergence-runbook.md). Single-env
rollback; no wire-format break.
DeleteVersion(s) _bin support (prerequisite):
- The DeleteVersion/DeleteVersions protos had NO _bin fields. Add additive
(backward-compatible) bytes file_info_bin/opts_bin (DeleteVersion) and repeated
bytes versions_bin + bytes opts_bin (DeleteVersions); regenerate the checked-in
prost struct.
- Client dual-writes them; server decodes them _bin-first with JSON fallback.
- These delete fields are kept OUT of the msgpack-only set (always dual-write)
until their own fallback counter reads zero across a window with the new
decoders fully deployed. DeleteVersion.raw_file_info stays JSON-only (no _bin
field yet).
Verification: cargo check/test on protos, config, ecstore, rustfs (incl. the six
delete request handler tests and a compat_json default-path test); clippy clean
on touched files; make pre-commit green.

* feat(internode): P3 cluster peer online/offline health metric
Land the safe observability core of P3 (grpc-optimization G6/G8): track each
internode peer's reachability and expose the offline count, for parity with
MinIO's minio_cluster_servers_offline_total. Pure instrumentation — peer
selection and quorum are unchanged.
- io-metrics: per-peer PeerHealthState { online, consecutive_failures } registry
plus record_peer_reachable/record_peer_unreachable. A peer flips offline after
N consecutive failures (dial failures or RPC-triggered evictions) and back
online on the next successful dial; the count of offline peers is published to
the rustfs_cluster_servers_offline_total gauge.
- config: RUSTFS_INTERNODE_OFFLINE_FAILURE_THRESHOLD (default 3, clamped >= 1).
- protos: build_channel marks the peer reachable on a successful dial and
unreachable on a dial failure; evict_failed_connection feeds the failure signal
too. Keyed by the real peer address, so control and bulk channels to one peer
share health state.
Deferred (documented in docs/grpc-optimization P3): startup prewarm (no clean
topology-ready hook yet), the offline fast-bypass in peer routing (consistency-
sensitive; must not change quorum), and idempotent-read-only retry. This commit
is observability only.
Verification: cargo check/test on io-metrics, config, protos (new peer-health
state-machine and threshold-clamp tests); clippy clean on touched files; make
pre-commit green.

* feat(internode): P3 control-channel prewarm + self-healing offline bypass
Add the remaining P3 connection-lifecycle levers (grpc-optimization G6/G8), both
env-gated and default-off so the base build is unchanged.
Prewarm (RUSTFS_INTERNODE_PREWARM, default off): RemoteDisk::new spawns a
best-effort background dial of the peer's control channel, deduped per peer
address, moving the connect cost off the first RPC. Failures fall through to the
existing lazy connect + recovery monitor.
Offline bypass (RUSTFS_INTERNODE_OFFLINE_BYPASS, default off): remote_disk
get_client/get_bulk_client fast-fail a peer already marked offline instead of
paying the connect timeout, so the erasure layer proceeds on quorum sooner. This
does NOT change quorum. It is self-healing: cluster_peer_should_bypass lets one
request per RUSTFS_INTERNODE_OFFLINE_REPROBE_SECS (default 5s) through to recover
the peer even with no background monitor, and the recovery monitor's own probe
path calls the client directly so it is never bypassed.
io-metrics gains cluster_peer_is_offline / cluster_peer_should_bypass (with a
per-peer re-probe timestamp). Scope: data path only — remote_locker (lock RPCs,
most consistency-sensitive) is left dual-writing/unbypassed as a follow-up.
Verification: cargo check/test on io-metrics, config, ecstore (new self-healing
bypass tests; all 105 rpc tests green); clippy clean on touched files; make
pre-commit green.

* docs(internode): add A/B benchmark runbook for gRPC optimization stages
Reproducible before/after collection procedure for grpc-optimization P0–P3.
Since every stage is env-gated, before/after is the same binary with different
env — no rebuild. Documents, per stage: the exact env toggles (baseline vs
enabled column), which existing bench script to run
(run_internode_transport_baseline.sh / run_four_node_cluster_failover_bench.sh),
the Prometheus metrics to capture, and the acceptance gates from the design docs
(e.g. lock p99 down >= 20% for P1, msgpack fallback counter = 0 before enabling
P2, correct rustfs_cluster_servers_offline_total for P3).
Live runs require a multi-node cluster + load tool + Prometheus scrape and cannot
be produced in a single-process sandbox; artifacts land under target/bench
(gitignored) and attach to the PR.

* feat(internode): P3-2 lock-path offline bypass + P3-3 idempotent read retry
Extend the offline bypass to the lock path and add opt-in retries for idempotent
reads (grpc-optimization P3-2/P3-3). Both env-gated and default-off/zero.
Offline bypass (lock path): factor the bypass decision into a shared pub(crate)
internode_offline_bypass_reason(addr) and call it from remote_locker::get_client
too, so lock RPCs to an offline peer fast-fail (letting dsync reach quorum
sooner) instead of paying the connect timeout. Does not change quorum; the
self-healing re-probe keeps peers recoverable. Gated by
RUSTFS_INTERNODE_OFFLINE_BYPASS (default off).
Idempotent read retry (P3-3): add execute_read_with_retry — a bounded,
exponential-backoff retry for read-only/reentrant RPCs on transient network
errors — and route disk_info through it. RUSTFS_INTERNODE_IDEMPOTENT_READ_RETRIES
defaults to 0 (disabled). Write/lock RPCs are never retried (quorum/idempotency
safety, per CLAUDE.md); the wrapper requires an Fn closure so only reads that
rebuild their request from borrowed inputs qualify.
Deferred: grpc.health.v1 (optional ecosystem-compat only; needs a new
tonic-health dep and 3-way hybrid-service wiring — internal needs are met by the
existing Ping RPC).
Verification: cargo check/test on config, ecstore (105 rpc tests green incl.
disk_info now via the retry wrapper); clippy clean on touched files; make
pre-commit green.

* feat(scripts): one-click internode gRPC A/B benchmark driver
Wrap the per-stage env matrix from the benchmark runbook into
scripts/run_internode_grpc_ab_bench.sh: given --stage <p0|p1|p2|p3> and --phase
<before|after>, it emits the stage/phase RUSTFS_INTERNODE_* server env to
<out-dir>/server-env.sh and runs the right underlying bench
(run_internode_transport_baseline.sh for p0/p1/p2, run_four_node_cluster_failover_bench.sh
for p3) into a labeled target/bench/internode-transport/<stage>-<phase>/.
Passthrough args after `--` reach the underlying bench; --dry-run previews the
env + command. The script is explicit that RUSTFS_INTERNODE_* are server env, so
for the load-driven stages the operator must restart rustfs with the emitted env
before the run; the docker four-node (p3) path exports them for a forwarding
compose. shellcheck-clean.
Runbook updated with a "One-click driver" section.

* chore(compose): forward RUSTFS_INTERNODE_* into the four-node cluster
The four-node local-build compose only forwarded a fixed whitelist of env, so
the internode gRPC knobs (grpc-optimization P0-P3) never reached the containers
and the A/B bench driver's "after" phase was a no-op. Forward the full
RUSTFS_INTERNODE_* set with defaults matching the binary defaults, so leaving
them unset is a no-op and the A/B driver can toggle a stage per phase.

* fix(internode): address Copilot review — retry health action + poison-safe peer health
Two review nits on #4337:
- P3-3 idempotent read retry (remote_disk.rs): execute_read_with_retry ran every
attempt through execute_with_timeout_for_op, which hardcodes
FailureHealthAction::MarkFailure. So the first transient error could flip the
disk faulty and short-circuit the remaining retries, and each attempt
over-counted the failure. Route all but the final attempt through
execute_with_timeout_for_op_and_health_action with IgnoreFailure; only the last
attempt marks faulty/evicts. No default impact (retries default 0).
- Peer-health helpers (io-metrics): record_peer_reachable/record_peer_unreachable,
cluster_peer_is_offline and cluster_peer_should_bypass early-returned on a
poisoned mutex, permanently stalling the offline gauge and bypass state after a
single panic. Recover via PoisonError::into_inner().

feat(admin): add MinIO-compatible IAM/IDP admin endpoints
Register and implement MinIO admin API compatibility for IAM/IDP:
- PUT /v3/import-iam-v2 and POST /v3/revoke-tokens/{userProvider}
- generic /v3/idp-config/{type}[/{name}] CRUD mapped onto existing config
- LDAP/OpenID service-account, policy-entities, and list-access-keys flows
Adds IamSys::delete_temp_account primitive to back STS token revocation.
revoke-tokens requires the broader ListUsers admin capability for
cross-user revocation (self-revocation only needs RemoveServiceAccount),
mirroring the cross-user guard used by the service-account handlers.
Registers admin route-policy inventory entries for every new route.
Unsupported LDAP/OpenID backends return honest compatibility errors.

yet gated, surfaced honestly via effective=false)
- profiling/trace and healthinfo/obdinfo/log diagnostics endpoints
- GET /v3/top/locks and POST /v3/force-unlock, backed by new
FastObjectLockManager::list_locks()/force_unlock() introspection
- speedtest routes where feasible

fix(replication): persist original mtime in MRF entries (backlog#867)
MRF delete entries did not persist the original delete-marker mtime, so
after a restart the recovery replay path reconstructed the delete without
a source timestamp. Downstream the replica delete-marker was stamped with
the replay time (now()) instead of the source mtime, causing delete-marker
timestamp divergence across clusters.
Extend the MrfReplicateEntry disk format with an optional deleteMarkerMtime
field (persisted as Unix nanoseconds) in both duplicate struct definitions
(rustfs-replication and rustfs-filemeta). DeletedObjectReplicationInfo now
persists delete_marker_mtime, and start_mrf_processor restores it onto the
reconstructed delete so the replica keeps the source timestamp.
Backward compatibility: the new key uses skip_serializing_if + serde
default, so historical MRF files without it decode to None and replay
falls back to the current time (pre-#867 behaviour). No panic or entry
loss on old files.
Closesrustfs/backlog#867
Add MinIO-compatible admin endpoints under the /v3 prefix, wired to real
RustFS subsystems where they exist and documented as compatibility-only
where they do not.
Replication (backlog#611):
- POST /v3/replication/diff: bounded on-demand scan of object versions,
returning versions whose replication status is PENDING or FAILED. Wired
to list_object_versions and the per-version replication status. Requires
the bucket to exist and have a replication configuration. The scan is
capped (REPLICATION_DIFF_MAX_SCAN) and reports IsTruncated when partial.
- GET /v3/replication/mrf: reports the failed-replication backlog (MinIO's
MRF concept) from the replication stats handle: aggregate failed count and
size per target plus in-queue counters. RustFS records failed replications
as aggregate counters and persists MRF entries without a runtime query API,
so per-object MRF rows are not enumerable; PerObjectEntriesAvailable is
always false to make that explicit.
Batch jobs (backlog#613):
- POST /v3/start-job, GET /v3/list-jobs, GET /v3/status-job,
GET /v3/describe-job, DELETE /v3/cancel-job.
- RustFS has no batch-job execution engine (no scheduler, queue, or worker),
so these implement MinIO request/response/error semantics only and never
fake execution or success: start-job parses and validates the job
definition then returns NotImplemented for known job types and
InvalidRequest for unknown ones; list-jobs returns an empty list;
status/describe/cancel validate jobId and return a no-such-job error.
All routes are registered with admin auth using existing AdminAction
variants (ReplicationDiff, GetReplicationMetricsAction, StartBatchJobAction,
ListBatchJobsAction, DescribeBatchJobAction, CancelBatchJobAction) and are
covered by the admin route-registration matrix and new handler unit tests.

security(swift): remove placeholder SSE module (backlog#646)
The Swift `encryption` module was a non-functional stub: `encrypt_data`
returned the plaintext unchanged while labeling it AES-256-GCM in the
object metadata, and `generate_iv` derived the IV from a timestamp
rather than a CSPRNG. It had no production caller (only a `pub mod`
declaration and one integration test), so wiring it in as-is would have
silently shipped plaintext advertised as ciphertext.
We are not supporting Swift server-side encryption for now, so remove
the module outright rather than keep a dangerous stub around:
- delete crates/protocols/src/swift/encryption.rs
- drop `pub mod encryption;` from swift/mod.rs
- remove the encryption case (and unused import) from the swift
integration test
The module reached main dubiously: it was introduced together with the
whole Swift API in commit 86e93624 ("fix(heal): canonicalize scanner
object-dir repairs (#3864)"), a 1665-file squash whose PR description
only covered the heal change and never mentioned Swift or SSE.

fix(multipart): serialize the part commit per uploadId to prevent mixed-generation shards (backlog#853)
Concurrently re-transmitting the same part could land two shard
generations across different disks: each shard is individually
bitrot-valid, so the corruption surfaces only as a silent mix at read
time.
The hazard is confined to rename_part, where two temp parts are moved
cross-disk onto the SAME final part path — interleaving there can leave
shards from two generations. Each concurrent stream already writes to its
own unique temp dir, so the encode/stream phase never conflicts and must
stay lock-free: holding a lock across it would serialize slow re-transmits
of the same part, break the S3 'last finisher wins' semantics, and cause
UploadPart lock-acquire timeouts (ServiceUnavailable).
Scope a write lock to the uploadId namespace around only the rename_part
commit, so each commit is atomic across disks and the last committer wins
consistently. Mirrors MinIO's per-uploadID NS lock; disjoint from the
object lock held by complete_multipart_upload (no lock-ordering cycle).
Honors opts.no_lock.
The pre-delete-before-rename half of backlog#853 was already fixed in
#4316; this completes the issue.
Adds an end-to-end regression test: six concurrent resends of the same
part must all succeed (no lock-acquire timeout), exactly one generation
stays visible, and the reassembled object equals one intact generation.
Closesrustfs/backlog#853
Three tests share the global list-objects mutation-sequence state (the
LIST_OBJECTS_MUTATION_SEQUENCE atomic and the per-bucket sequence map)
and all call reset_list_objects_mutation_sequences_for_test(), but only
observed_mutation_persists_namespace_journal_high_water was marked
#[serial_test::serial]. The serial lock only excludes tests that also
carry the attribute, so the unmarked tests still ran concurrently with
it: the journal test's persist of "bucket" -> 11 could land after the
recovery test's reset, making it observe 11 instead of the expected 9
(flaky under the default multi-threaded test runner, green with
--test-threads=1).
Add #[serial_test::serial] to the two unmarked tests:
- persistent_key_only_index_load_recovers_mutation_sequence_from_journal
- list_objects_mutation_sequence_advances_per_bucket
Unique bucket names alone would not fix this: the per-bucket assertions
in list_objects_mutation_sequence_advances_per_bucket check exact values
produced by the single global atomic counter, which any concurrent
observe call perturbs, and every reset zeroes that global state for
whichever peer is mid-flight.

fix(filemeta): use struct-init to satisfy clippy::field_reassign_with_default
The replication_info_equals test constructed FileInfo via
`let mut x = FileInfo::default()` followed by field reassignment, which
clippy::field_reassign_with_default (deny-by-default under -D warnings)
rejects on the lib-test target, breaking `Test and Lint` CI on every PR.
Rewrite the three constructions using struct-init + ..Default::default().
Test-only change; behavior unchanged.
Add two durable architecture references grounded in current code:
- minio-rustfs-router-compatibility.md: MinIO cmd/api-router.go (S3
object/bucket) and cmd/admin-router.go (admin /v3, /v4) vs RustFS
implementation status, with per-row landing points and a gaps-only
checklist of still-missing admin endpoints (profiling, healthinfo,
LDAP IDP config, replication diff, MRF, batch, locks, speedtest,
log stream, top, trace).
- minio-file-format-compat.md: xl.meta (meta_ver 3 write, <=3 read,
XL2 magic, rs-vandermonde, HighwayHash256 bitrot, inline data) and
.metadata.bin bucket-metadata interop matrix for the backlog#580
items, plus old-RustFS -> new migration and a phased plan.
Cross-links s3-compatibility-matrix.md and admin-route-action-snapshot.md
and indexes both docs in docs/architecture/README.md.

The peer `DeleteBucketMetadata` RPC handler was a stub that returned
success without doing anything, and the delete-bucket flow never sent
the notification in the first place. As a result, after a bucket was
deleted other nodes kept serving its stale cached metadata.
Wire the whole path end to end:
- ecstore: add an in-memory `remove_bucket_metadata` (free fn) and
`BucketMetadataSys::remove`, the counterpart to `set_bucket_metadata`,
and export it through the `api::bucket::metadata_sys` facade.
- node_service: `handle_delete_bucket_metadata` now validates the bucket
name and actually drops the cached metadata for it.
- bucket_usecase: after a successful delete_bucket, notify peers via
`notification_sys.delete_bucket_metadata` in the background, symmetric
to the existing `notify_bucket_metadata_reload` path.
Also update the delete-bucket-metadata unit test to assert the
empty-bucket rejection instead of the old always-success stub, and drop
an unused `tracing::debug` test import left over from #4322.

Two compounding defects let a truncated shard corrupt a GET (ranged GET could
return HTTP 200 with wrong bytes):
- `BitrotReader::read` returned `Ok(short_len)` when the shard stream hit EOF
before filling the caller's buffer. With `skip_verify` /
`HashAlgorithm::None` / parity=0 there is no hash to catch it, so the short
shard was accepted and every downstream byte shifted.
- `ParallelReader.offset` was set once and never advanced per stripe, so every
stripe after the first reused the first stripe's geometry and the last-stripe
length clamp was wrong.
Fix both (they are mutually required):
- `BitrotReader::read` now errors (`UnexpectedEof`) on a short read, before and
independent of the bitrot hash check, so it fires under skip-verify/no-hash
too. The caller sizes the buffer to the expected per-stripe shard length, so
"buffer not filled" == "shard truncated". A short read routes through the
existing `errs[i]` path, dropping that reader from the stripe so parity
reconstruction engages; with parity=0 the stripe fails read quorum and the GET
errors loudly instead of streaming shifted bytes. Mirrors MinIO's
`parallelReader.Read` (`n != shardSize` -> reader failed).
- `ParallelReader::read` / `read_lockstep` advance `self.offset += shard_size`
per stripe so the per-stripe expected length (incl. the shorter final stripe)
is exact, matching the correct pattern already used by heal.
Updates three bitrot tests that used an obsolete oversized-buffer pattern to
size per-stripe (as the real decode/heal paths do), and adds a regression test
that a truncated shard errors under None/HighwayHash + skip_verify.

fix(heal): remove useless .into() conversion in heal error path

fix(filemeta): key round-tripped replication reset state by canonical header (backlog#799 B19->B16)
`get_internal_replication_state` stored the reset status under the bare ARN after
stripping the internal prefix, while the write and lookup sides
(`get_replication_state` / `ReplicationState::target_state`) use the full
`target_reset_header(arn)` key. A `target_state` fallback masked the lookup miss,
but the map stayed keyed inconsistently (bare on read, full on write), which can
drop reset state across merge/reflatten cycles.
Store the canonical `target_reset_header(arn)` key on read so the map is
consistent everywhere; the lookup fallback becomes belt-and-suspenders rather
than load-bearing. Adds a round-trip regression test.

Second TODO-convergence round over the current tree (backlog#646). All
line numbers in the old inventory had gone stale after the set_disk /
diagnostics / cluster refactors, so this re-scans and reduces the marker
count from 144 to 99.
STALE removals (comment describes already-implemented behavior, or dead
commented-out blocks) across ecstore (set_disk ops/core, store,
cluster/rpc, bucket/metadata_sys, services), iam, filemeta, s3select and
rustfs auth/object_usecase. No behavior change.
Safe fills, each verified:
- filemeta: replication_info_equals now also compares
replication_state_internal (function currently has no callers; adds a
regression test).
- bitrot: drop the confirmed-unused `_want` parameter from bitrot_verify
and the now-unused `sum` on LocalDisk::bitrot_verify, removing a
Bytes::copy_from_slice allocation. Streaming verify uses the file's
embedded per-shard hash, never the passed sum.
- signer: rename v4_ignored_headers -> V4_IGNORED_HEADERS and drop the
non_upper_case_globals allow.
- admin/heal: test_decode was #[ignore]d and used serde_urlencoded on a
JSON body (would panic); rewire to serde_json::from_slice to match the
production decode path, add assertions, un-ignore.

fix(ecstore): reject renewing a misplaced drive into the wrong set (backlog#799 B19)
`renew_disk` located the drive's (set, disk) position from its own format via
`find_disk_index`, but never checked that the resolved `set_idx` matched this
`SetDisks`' own `set_index` before inserting the drive into `self.disks`. A
drive whose format places it in another set would be claimed by this set too,
so two sets could manage the same drive and degrade together.
Skip (with a warning) when `set_idx != self.set_index`.

fix(replication): don't silently swallow resync status persistence failure (backlog#799 B23)
After a resync computes a new replication status, it persists it via
`put_object_metadata` but discarded the `Err` case (`if let Ok(u) = ...`). A
failure left the object's on-disk replication status disagreeing with the resync
result with no signal at all. Log the failure at warn level instead.

heal_object wrote healed shards to .rustfs/tmp/<uuid>/ and only removed that tmp
dir on the success path (the final delete_all). Three early exits after the tmp
shards were written leaked the dir:
- `erasure.heal(...)?` failing midway,
- the `disks_to_heal_count == 0` early return, and
- the `?` on the post-rename remote data-dir delete.
Add the tmp cleanup before the first two, and downgrade the remote data-dir
cleanup failure to a warning (the healed shard is already renamed into place, so
that cleanup failing must not abort the heal or leak the tmp shards).

`MetaDeleteMarker::decode_from` returned an error on any field key it didn't
recognize, unlike `MetaObject::decode_from` / `MetaObjectV1::decode_from`, which
skip unknown fields. That breaks forward compatibility: a delete marker written
by a newer version with an extra key fails to decode on an older binary.
Skip the unknown field's value (`skip_msgp_value`) and continue, matching the
object decoders. Adds a regression test.

`rename_part` unconditionally ran `cleanup_multipart_path([part.N, part.N.meta])`
on every disk *before* the per-disk rename fan-out. The per-disk `rename_part`
already replaces `part.N` atomically (std::fs::rename) and rewrites `part.N.meta`,
so the pre-delete is redundant — and destructive: it removed an already-committed
(ACKed) part on all disks before the new rename landed, so a re-upload of the same
part that then failed write quorum destroyed the committed part outright.
Remove the pre-rename cleanup and rely on the atomic rename to overwrite in place;
the quorum-failure rollback below is unchanged. No behaviour change on the success
paths (first upload / retry both end with part.N replaced), verified by the
existing multipart suite.
Refs backlog#799 (B4). The remaining half of B4 — serializing concurrent
same-part uploads with an uploadId-scoped lock so two generations can't be mixed
across disks — is a larger concurrency change tracked as a follow-up on the issue.
MRF delete replay reconstructed the delete with `..Default::default()`, leaving
`replication_state = None`. `replicate_delete` derives its target set purely
from `replication_state.replicate_decision_str`, so an empty state produced an
empty decision -> zero targets: the replayed delete contacted no remote at all,
a silent no-op that left replicas permanently diverged after a restart.
The MRF entry doesn't persist the decision and the source object is already
gone, so re-derive it from the live bucket config at replay time via
`check_replicate_delete` — mirroring the object heal path
(`get_heal_replicate_object_info`) — and set it on the reconstructed delete's
`replication_state`. This is a contained fix with no change to the on-disk MRF
format.
Refs backlog#799 (B9).
Note: the source delete-marker mtime is still not persisted in the MRF entry,
so a replayed delete marker is stamped with the replay time on the target. That
is a separate, minor consistency nuance (the delete now propagates correctly)
and can be addressed by extending the MRF entry format in a follow-up.
The MRF persister accumulated overflow entries in `pending`, flushed them with
`flush_mrf_to_disk`, and cleared `pending` on success. But `flush_mrf_to_disk`
*overwrites* the whole MRF file with exactly the entries passed. After flushing
batch A (file = A) and clearing, the next flush wrote batch B and thereby
overwrote the file to contain only B — and the MRF file is only replayed (and
cleared) at startup, never during the run, so batch A's entries were silently
lost. A crash after the B flush lost all of batch A's pending replications.
Keep `pending` cumulative (the file must hold the full set of overflow entries
for the run) and rewrite the whole set on each flush instead of clearing after
success:
- flush eagerly once 1 000 *new* entries accumulate since the last write
(measured against the flushed length, so a large backlog isn't rewritten on
every add), and on the 10s tick when dirty;
- bound the in-memory/on-disk backlog with `MRF_PENDING_CAP` (200 000) and log
once when the cap is hit rather than growing without limit.
Refs backlog#799 (B10).
The resync result verification HEADed the target after replicating and counted
the outcome with inverted error handling:
- for a delete marker, ANY HEAD error (timeout, 5xx, auth, malformed) was
counted as replicated (success);
- for a versioned object against an AWS-style target, HEAD was sent with the
RustFS UUID versionId, which AWS rejects with 400, so a well-replicated
object was counted as failed.
Classify the error before counting:
- delete marker: only a definitive 404/NoSuchKey or 405/MethodNotAllowed
confirms the marker propagated (`is_retryable_delete_replication_head_error`
== false); any retryable/ambiguous error now counts as failed;
- versioned object with a version-id-format rejection: re-verify via
`head_object_fallback` (versionId-less HEAD) before deciding — present ->
replicated, absent/error -> failed;
- all other errors: failed, as before.
Reuses the existing, unit-tested classifier helpers. Verified against the
existing resyncer suite (24 tests).
Refs backlog#799 (B13).
During resync against an AWS-style target that rejects RustFS UUID versionIds,
the code retries HEAD without a versionId and compares ETags. On a match it set
`replication_action = None` ("already in sync, nothing to copy") but did not
return, so control fell through to `if replication_action != ReplicationAction::All`
— a branch meant only for the unsupported metadata-only case — and stamped the
object FAILED with "metadata-only replication is not implemented". The target
already held an identical object, yet the source recorded FAILED forever, so
AWS-style targets never converged and the MRF kept re-queuing.
Handle `ReplicationAction::None` explicitly before that branch: record it as
Completed (with the resync timestamp/`replication_resynced` bookkeeping for
ExistingObject + reset_id, mirroring the HEAD-success None path) and return.
Only `ReplicationAction::Metadata` now takes the metadata-unsupported failure
branch; `All` still proceeds to the copy. This path is the only way `None`
reaches that point (the HEAD-success None case already returns earlier).
Refs backlog#799 (B11).
`MultiWriter` recorded per-writer failures only in a private `errs` vector and
nulled the failed writer locally, but `put_object` never used that to prune the
disk set: `rename_data` ran over the full `shuffle_disks`, so a disk that took a
short/failed write still had its truncated shard renamed into place and counted
as an online disk. The object then claimed N good shards while one was
short/corrupt, so a single later disk failure could drop it below reconstructable
quorum — silent data loss.
- `write_shard`: null the writer on a generic write error too (not only on
`ShortWrite`), so a failed writer is uniformly represented as `None` — matching
`shutdown_writer`, which already does this.
- `put_object`: after encode, drop every disk whose writer failed
(`drop_failed_writer_disks`) from `shuffle_disks` before `rename_data`, and
re-check write quorum over the survivors. `rename_data` already re-checks
quorum and rolls back if too few disks remain, so excluded disks are neither
committed nor counted (MinIO sets failed writers to nil before `renameData`).
Adds unit tests for the exclusion/quorum accounting.
Refs backlog#799 (B3).
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).
PR #4220 added a purge for orphan empty-directory trees (folder keys with
no xl.meta) on the delete path, but the guard only accepted
object-not-found. Over the real HTTP DELETE path the guard is never
reached: `del_opts` pins `version_id = Uuid::nil()` for directory keys, so
the missing dir object fails the specific-version lookup with
version-not-found (FileVersionNotFound), not object-not-found. The guard
short-circuits, the store returns the error, and the API layer turns it
into a fake 204 — the ghost folder survives, exactly the #4189 symptom.
The existing unit tests passed because they call
`purge_orphan_dir_object` directly, bypassing the nil-version lookup.
Accept both misses in the guard (extracted as
`should_purge_orphan_dir_on_missing`) so the folder delete actually takes
effect. Non-directory keys and non-miss errors (e.g. quorum failures) are
unaffected; the cross-disk data-safety refusal in
`purge_orphan_dir_object` is unchanged.
Verified end-to-end against a running 4-disk erasure server: DELETE of a
planted orphan `ghost/` tree now purges it on all drives and clears the
listing, a real object under the same prefix is untouched, and a prefix
holding real data on any drive is refused (all drives preserved).
Adds predicate regression tests covering version-not-found /
object-not-found on directory keys, and the negative cases.
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.
