9575032b4c volume: forward fsync=true to replicas in ReplicatedWrite (#10805)
* volume: forward fsync=true to replicas in ReplicatedWrite

When a write request carries fsync=true, only the primary volume server
flushed to disk: the replica fan-out URL in ReplicatedWrite only carried
type/ttl/ts/cm, so replicas always wrote without fsync even when the
client explicitly requested a durable write.

Forward the fsync request parameter to the replica volume servers so a
durable write means every replica has flushed to disk, not just the
primary. Replicas without fsync are untouched (zero behavior change).

* storage: flush a durable write inline while stopping

The fsync flag on the write path really selects the async batch worker,
and it was switched off once the store is stopping. So a fsync=true write
landing during the pre-stop drain got acked without ever being flushed -
and now that ReplicatedWrite forwards fsync, that covers replicas too.

Flush it inline instead of queueing it. The drain keeps accepting writes,
which is the whole point of preStopSeconds, and the ack still means the
.dat is on disk. If the fsync fails, the append comes back off the .dat
and the needle map goes back to what it pointed at before, so nothing
resolves to an offset past the truncated end.

* storage: make the store's stopping flag atomic

SetStopping runs on the signal handler goroutine while the write and
vacuum paths read the flag, so every read of it was racy. Nothing about
the shutdown ordering changes; only the flag itself is now safe to read.

* topology: check the errors the replication test was dropping

The mock replica ignored its response write and the mock master ignored
whatever Serve returned, so a broken mock would have shown up as a
confusing timeout rather than a failure. Also drops the explicit listener
close: grpc.Server.Stop already closes the listener it was given.

Chris Lu 487b93eb49 fix(volume): don't panic on read when needle map is nil (#9342)
* fix(volume): don't panic on read when needle map is nil

A failed CommitCompact reload (and #9335's new error path for a
remote-tiered volume with a stray .vif but no .idx) leaves v.nm == nil
on a volume that's still in the store. readNeedle / readNeedleDataInto
dereferenced v.nm with no guard, so the next GET segfaulted the
http handler instead of returning an error the client could retry on
another replica.

Add the same v.nm == nil check the other Volume accessors already use,
including the slow-read inner loop where the lock is released between
iterations and a failed reload can race in.

Fixes #9339.

* match rust nm-nil read behavior; trim comments

seaweed-volume's read_needle_with_option / re_lookup_needle_data_offset
already lift Option<NeedleMap> through ok_or(NotFound). Use ErrorNotFound
on the Go side too instead of a generic 500-mapped error so both volume
servers respond identically when v.nm is nil.

* log once when reads hit nil needle map

ErrorNotFound alone hides the real cause: a half-loaded volume just
returns 404s and the operator has nothing to grep for. Add a once-per-
volume Errorf on the nil path, reset on successful load. Mirror the
same in seaweed-volume via nm_or_not_found().

* trim comments

* drop once-flag, log inline on every nil-nm read

Ping QiuandClaude Opus 4.5 5c8de5e282 fix: close volumes and EC shards in tests for Windows compatibility (#8152)
* fix: close volumes and EC shards in tests to prevent Windows cleanup failures

On Windows, t.TempDir() cleanup fails when test files are still open
because Windows enforces mandatory file locking. Add defer v.Close(),
defer store.Close(), and EC volume cleanup to ensure all file handles
are released before temp directory removal.

* refactor: extract closeEcVolumes helper to reduce duplication

Address code review feedback by extracting the repeated EC volume
cleanup loop into a closeEcVolumes() helper function.
