* fix(iam): load IAM bootstrap snapshot without namespace locks
IAM bootstrap (init_iam_sys -> load_all) read every config object with
default ObjectOptions (no_lock=false), so each read acquired a
distributed namespace read lock. Lock quorum is counted over cluster
nodes and unreachable peers are hard failures, so during a sequential
restart the very first read failed with
"Quorum not reached: required 2, achieved 0" and IAM could not come up
until enough peers' lock RPC surfaces converged - even when the storage
read quorum was already satisfiable (rustfs#4304).
Extend the startup contract from rustfs#4056 ("startup metadata I/O must
not require namespace locks") to the IAM bootstrap path:
- Introduce LoadMode {Locked, BootstrapNoLock} and plumb it through the
load_all chain (groups, users, policies, mapped policies and their
concurrent variants) down to the storage read options.
- load_all now performs all reads with no_lock=true; on-line
single-object loads via the Store trait keep locked semantics.
- Fail-closed behavior is unchanged: any loader error still aborts the
whole snapshot load.
Safety: config objects are atomic whole-object writes, so a lock-free
read only observes an old or a new value; staleness is bounded by the
existing periodic IAM reload. Listing (walk) never took namespace locks,
and maybe_schedule_lazy_rewrite stays a best-effort background task.
Verification:
- cargo test -p rustfs-iam --lib (153 passed, incl. new LoadMode tests)
- cargo clippy -p rustfs-iam --all-targets
- cargo check -p rustfs
- make pre-commit

* test(iam): sequential-restart regression test for lock-free bootstrap
Add an integration test reproducing the rustfs#4304 failure mode against
a real 4-disk temp-dir ECStore:
- Seed IAM group data in single-node mode, then flip the runtime into
distributed-erasure mode. new_ns_lock now builds a distributed lock
over the set's (empty) lock-client list, so every namespace-locked
read fails exactly like a sequential restart with unreachable peers
(lock quorum unavailable, storage read quorum healthy).
- Assert the locked load_group path fails in that state, while the
bulk snapshot load_all (no_lock plumbing from the previous commit)
succeeds, and the data survives intact once single-node mode is
restored.
Reverse-verified: temporarily switching load_all back to the locked
mode makes the test fail, so it genuinely guards the contract.
Verification:
- cargo test -p rustfs-iam --test iam_bootstrap_no_lock_test
- cargo test -p rustfs-iam --lib

* test(iam): route test ECStore imports through ecstore_test_compat boundary
The new integration test imported rustfs_ecstore facade paths directly,
tripping three architecture migration rules. Move every ECStore import
behind crates/iam/tests/ecstore_test_compat/mod.rs (the sanctioned
test-compat pattern), and register that module as a reviewed test-only
global-facade boundary in check_architecture_migration_rules.sh: the
sequential-restart regression test needs api::global::update_erasure_type
to flip into distributed-erasure mode for lock-quorum fault injection.
Verification:
- ./scripts/check_architecture_migration_rules.sh
- cargo test -p rustfs-iam --test iam_bootstrap_no_lock_test
- make pre-commit

* feat(server): expose readiness blocking reason + rolling-restart runbook
Operators hitting the rustfs#4304 sequential cold start could not tell
from the outside why a node stayed unavailable. Three additions:
- The readiness gate's 503 now names the blocking dependency in both the
body ("Service not ready: waiting for storage_quorum") and a new
x-rustfs-readiness-pending header (storage_quorum | iam |
startup_finalization), derived from the current startup stage.
/health/ready already returned details + degradedReasons; this covers
the plain S3 requests that hit the gate.
- IAM bootstrap retry logs now carry an actionable `hint` field that
classifies the failure (storage read quorum vs lock quorum vs
uninitialized metadata) instead of only echoing the storage error.
- New docs/operations/rolling-restart.md runbook: correct rolling
restart procedure, sequential cold-start expectations (degraded ->
auto-recovery), readiness signal reference, and
RUSTFS_STARTUP_READINESS_MAX_WAIT_SECS guidance.
Verification:
- cargo test -p rustfs --lib -- hint_tests service_not_ready readiness_pending
- make pre-commit

* feat(iam): notification-path cache refreshes read without namespace locks (#4368)
P3 step 1 of rustfs/backlog#884 (scoped down from full MinIO readConfig
alignment after review): cross-node notification handlers
(group/policy/policy-mapping/user) refresh the local IAM cache with
single-object reads that previously took distributed namespace read
locks. These refreshes are asynchronous, best-effort, and already
stale-tolerant (the periodic reload converges them), so a node-counted
lock quorum failure or lock RPC hiccup on a peer must not fail them —
the same rationale as the lock-free bootstrap load_all (rustfs#4304).
- Store trait: add load_user_no_lock / load_group_no_lock /
load_policy_doc_no_lock / load_mapped_policy_no_lock with defaults
forwarding to the locked variants, so existing implementations and
test mocks keep their behavior.
- ObjectStore overrides them via the existing LoadMode::BootstrapNoLock
plumbing. Deletions triggered by the handlers keep locked writes.
- manager.rs: the four *_notification_handler paths (8 call sites)
switch to the lock-free variants.
- Integration test: while the lock quorum is unavailable (DistErasure
with empty lockers), load_group_no_lock must succeed exactly where
the locked load_group fails.
Request-path loads (check_key, verify_temp_user_persistence) and admin
write-then-reload paths intentionally stay locked: load_user_identity
embeds expiry deletions, so those need the side-effect extraction
tracked in rustfs/backlog#884 before going lock-free.
Verification:
- cargo test -p rustfs-iam --lib (156 passed)
- cargo test -p rustfs-iam --test iam_bootstrap_no_lock_test

* fix(server): drop unused iam_bootstrap_failure_hint import in tests
The hint tests live in their own hint_tests module with a local import;
the stale re-import in mod tests failed clippy's -D warnings on the
Test and Lint CI variants.
