* fix(volume): harden volume copy validation * fix(volume): use stream context for ReadVolumeFileStatus in VolumeCopy ReadVolumeFileStatus ran on context.Background() while the adjacent VolumeStatus call used stream.Context(), an inconsistency left over from the context revert in #11252. Use stream.Context() consistently so the source status check is cancelled with the VolumeCopy stream. * fix(volume): reserve destination before deleting existing replica FindFreeLocation now runs before DeleteVolume so a full target fails without destroying the existing replica. Previously, when the initial VolumeStatus check failed (advisory) but ReadVolumeFileStatus succeeded, the existing replica was deleted before a destination was reserved, risking data loss if no location had enough free space. Add a regression test verifying the existing replica survives when the destination is full and the initial status check fails. * fix(volume): count replaced replica slot in FindFreeLocation FindFreeLocation now accepts the volume being replaced so its slot is treated as available. Without this, a location at its MaxVolumeCount limit could not replace its sole replica even though deleting it would free the slot. VolumeCopy passes the volume ID so destination selection succeeds before the existing replica is deleted. Add TestVolumeCopyReplacesReplicaAtSlotLimit covering a single-slot location that must replace its only replica. --------- Co-authored-by: Chris Lu <chris.lu@gmail.com>
