A completed multipart upload's staging cleanup prunes empty parent
directories up to the volume root, which removes shared prefixes such as
`data-movement/` and the per-object `<sha>/` while a concurrent
new_multipart_upload builds its destination chain below them. The writer
holds a descriptor to the pruned component, so its next handle-relative
mkdirat fails NotFound. Because rename never retried NotFound, the cleanup
fan-out failed several disks in the same window and broke write quorum.
Give rename preparation its own retry rule: a NotFound is retried once per
component below the base directory, so a rebuilt walk outlasts a pruning
walk, which removes ancestors monotonically upward and stops at the base.
A destination whose parent is the base keeps NotFound terminal, so
speculative cleanup renames still fail fast, and the base is only ever
opened, never created, so a genuinely missing base still fails. The rename
itself keeps its own budget and its unchanged NotFound-is-terminal rule.
test(ecstore): assert inline fanout gate on deterministic scheduled metric
non_inline_data_read_early_stop_does_not_add_inline_fanout_on_unequal_layout
compared disk_call_counters::KIND_READ_VERSION totals between the two-phase
read-plan gate being off and on. That counter records inside each spawned
fanout task, so the single-pending inline hedge read races the early-stop
abort_all(): whether the hedge task gets its first poll before cancellation
decides a 4-vs-5 count per read. Under concurrent nextest load the two reads
can disagree (reproduced locally at ~5% when run beside one other test,
matching the CI failure on PR #6961).
Assert on the rustfs_io_get_object_metadata_fanout_scheduled histogram
instead, which records the scheduling decision synchronously in the fanout
loop and is deterministic, using the CapturingRecorder + current-thread
runtime pattern already used by the neighboring tests in this module.
A replicated version purge reaches the peer without the governance
bypass header, so a GOVERNANCE-retained version deleted on the source
with x-amz-bypass-governance-retention was rejected by the peer's WORM
deletion gate forever: retryStats ended at a permanent failed count and
the sites stayed diverged (issue #6850).
The source is authoritative for such a purge: the same WORM gate
already ran there, and GOVERNANCE retention with an authorized bypass
is the only lock state it can purge through. The peer's commit-time
deletion gate now treats an authorized replication delete addressed to
an explicit version as carrying that judged bypass, reusing the same
trust judgment as the replication write exemption
(ObjectOptions::replication_request, set only after the handler
authorized ReplicateDeleteAction). COMPLIANCE retention and legal hold
keep blocking replicated purges, and a plain client delete without the
bypass header stays rejected.
fix(ecstore): require verification source for degraded GET
Fail closed when reconstruction has only an exact decode quorum, because no surplus source remains to validate the rebuilt data. Cover both erasure engines and the data-shards-only rollout gate.

fix(ecstore): hedge data-only GET with parity
Route the opt-in data-shards-only lockstep path through the bounded parity race and preserve deferred parity reserves across canceled hedges.

Use the seqlock version as the publication fence and keep payload reads relaxed while validating the final version. This reduces ordering overhead in disk metric recording and snapshot collection without changing the rolling-window contract.

fix(ecstore): classify system metadata volume failures
Preserve retryable quorum errors when system metadata reads or writes encounter missing volumes, and cover the create-bucket data-usage path with regressions.
