* fix(admin): replay recorded IAM deletions in site replication retry drain
An IAM deletion whose peer delivery failed during an outage window was
previously unrecoverable without a manual repair: the collapsed retry
entry carries no body, the snapshot resend cannot express "this entity
no longer exists", and the drain escalated the entry into a permanent
marker. The deleted user kept working credentials on the peer until an
operator intervened — a security exposure (backlog#2071).
Record the verbatim deletion body (user/policy/group-removal/
policy-mapping-clear/service-account) in the persisted state, in the
same transaction as the retry-event upsert. The drain now replays the
recorded deletions before the snapshot resend — snapshot-after ordering
restores any entity recreated locally in the meantime — and settles the
collapsed entry when its whole liability is provably replayed. Entries
that predate recording, merge with legacy rows, or overflow the
per-peer record cap keep the escalation semantics: only explicitly
recorded deletion events are ever replayed, never a cross-site diff.
The peer apply handlers become idempotent for deletion shapes (missing
policy/group/member tolerated, matching the existing user-delete
tolerance), so a replayed deletion that already converged settles
instead of wedging the drain. The IAM change hook now attempts every
peer instead of failing fast, so a multi-site broadcast books a retry
entry (and deletion record) for each unreachable peer rather than only
the first. Repair success and peer removal clear the affected peer's
records alongside the entries they accompany.
* fix(admin): probe recovered peers to lift retry drain backoff
A bucket created while a peer was unreachable accumulated three failed
deliveries and entered exponential backoff (2400s and up, capped at a
day). After the peer recovered, the reconcile tick's drain kept
skipping the entry until the backoff elapsed, so the site stayed
diverged — NoSuchBucket resync noise on the source, missing bucket on
the peer — for up to 24 hours with nothing else driving convergence
(backlog#2071, round-four R1.6).
Split reachability from replay: the drain now probes each peer whose
replayable backlog is held back only by backoff (one cheap devnull POST
per peer per tick) and promotes the backlog when the peer answers, so a
recovered peer converges at the next 600s tick. A failed probe advances
nothing — retry counts only move on real delivery attempts, keeping the
exponential schedule intact for a peer that is genuinely down. The base
backoff still floors re-attempts against a reachable peer that keeps
rejecting a delivery. SITE_REPLICATION_RETRY_FAILED_AFTER stays at 3:
the flag is retryStats visibility only, and with the probe in place an
early failed mark is a timely operator signal rather than a dead end.
The drain tick also logs an operator-visible warning whenever the queue
holds failed or escalated entries, instead of backing off in silence.
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.
New RustFS Upgrade Test workflow (SUITE: upgrade) runs first in the
nightly functional chain:
- Nightly GNU Build -> Upgrade -> S3 -> KMS -> Tier -> Pool/Heal -> Security
- S3 compatibility now triggers on "RustFS Upgrade Test" completion, so an
upgrade regression gates the rest of the chain.
- Security suite moves to the end, after pool/heal, on the shared VMs.
- The upgrade suite drives auto-testing's rustfs-upgrade-test.sh
(UPG-101..402): seed golden data/identity/config on the OLD deb, upgrade
in place to the NEW deb, verify byte-identical preservation, and publish
functional-reports/upgrade/<date>.md.
- Add the Upgrade tab to every dashboard index writer so the shared
functional/index.html stays consistent.
Under the cargo test fallback (threads in one process), tests that touch
the process-global scanner cycle recovery status or the global usage-save
metrics raced each other and failed randomly in full-suite runs.
Mark all touchers with #[serial] per docs/testing/README.md:
- 22 tests reading or writing scanner_cycle_recovery_status() via
load_scanner_cycle_state_for_startup / reset_scanner_cycle_recovery
- 24 tests mutating global_metrics() usage-save counters via
store_data_usage_in_backend*, which raced the existing serial
test_deferred_usage_save_keeps_last_real_save_metric
No-op under nextest, which isolates each test in its own process.
Align object-capacity refresh defaults with the production-oriented environment values and keep docs, script examples, and tests in sync.

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.
