Important bug fixes (new store):
- Fix OSDs possibly refusing to start with "write metadata failed at offset xxx: Invalid argument"
(fix buffer alignment during initial garbage collection)
- Rollback change from 3.0.4 - on-disk garbage entries are not skipped on start again. This change
doesn't have any impact normally, but OSDs originally running 3.0.0-3.0.2 and then upgraded
to 3.0.9 may hit a bug where 3.0.9 refuses to start due to entries marked as garbage too
early and flushed to disk in 3.0.0-3.0.2.
Other changes:
- Auto-select the only RDMA device/port if there is only one
- Rollback one 3.0.9 change - there was no actual use-after-free :)
(the problem was only relevant to an unstable development version)
- Fix `vitastor-nfs --trace` option
- Fix an unintended 1 second sleep in vitastor-cli rm-data
- Fix inode statistics not being cleared for a deleted pool
- Fix print to stdout in client
- Fix broken garbage collection in the new store leading to very high memory usage
- Make the new store do full garbage collection on OSD startup by default (can be turned off with a new gc_on_start parameter)
- Make startup logging with the new store more informative, allow to log amount of garbage with log_level > 1
- Fix clients reading from snapshots incorrectly on retries (for example when OSDs were restarted during read)
- Fix a possible "send-after-free" in OSD which could probably also affect snapshot reads
- Fix OSD crashing when handling a read_bitmap operation from a deleted object with the new store
- Surrogate increment-only peer IDs are now used instead of file descriptor numbers,
and client cleanup sequence is reworked in another attempt to fix a possible PG hang
in 'peering' states. The history of this bug is still unclear and it still hasn't been
reproduced in tests, but several users have reported it since 3.0.4 (only with enabled RDMA).
- Fix a minor bug where an OSD could skip reporting misplaced PG state when moving
an object in non-immediate_commit mode.
- Add Ubuntu 26.04 (Resolute Raccoon) support and patches for qemu 10.2 and libvirt 12.0
