- Implement a new "vitastor-disk purge" command to remove OSDs with safety checks
- Implement a new "vitastor-cli rm-osd" command to only remove OSD metadata from etcd
- Fix a bug where the monitor could ignore OSD removal and other /osd/stats key changes
- Fix a bug where garbage could be returned when reading objects being written at the same time
- Fix a rare write stall where journal space could be not reclaimed where there
were no new operations in the flush queue
- Fix a rare peering stall caused by a previous long listing operations queues limiting attempt
- Fix total object count statistic in OSD on object creation
- Add missing offset&len into vitastor-disk dump-journal for big_writes, fix JSON format
- Make vitastor-cli print help on missing command
- Make vitastor-cli translate all '-' to '_' in CLI options
"In-flight" versions are added into dirty_db when writes are enqueued. And they
weren't ignored by subsequent reads even though they didn't have data location yet.
This bug was leading to test_heal.sh not passing sometimes with replicated setups.
- Fix QEMU driver compatibility with QEMU 7.0 and < 2.9
- Add patches for pve-qemu-kvm 7.1 (PVE 7.3) and pve-qemu-kvm 6.2 (PVE 7.2)
- Fix Proxmox driver location in the pve-storage-vitastor package
- Disable HDD autodetection in non-hybrid mode
- Explicitly warn about a buggy kernels on -EAGAIN in io_uring
- Final fix for the lack of zeroing out of old metadata entries
(do not crash with "big_write journal_entry was allocated over another object"
in some cases after an unclean OSD shutdown)
- Wait for data writes before fsyncing data if data fsync is enabled
- Never try to wait for free space inside blockstore thus stalling OSDs
- Fix a rare crash in osd_peering due to callback ordering
- Fix a rare duplication of ping & op message IDs
- Fix a rare use-after-free during pings
- Add --force to vitastor-disk read-sb
- Make vitastor-disk dump metadata object IDs in hex, add forgotten commas
- Fix vitastor-disk SCSI disk cache check
If a crash occurs during flushing a redirect-write it may happen so that
the disk contains both old and new metadata entries. This is OK, but prior
to 0.8.0 after this situation OSDs started without problem, but then they
crashed after some more overwrites with a "tried to overwrite non-zero
metadata entry" error. 0.8.0 introduced a change that was intended to fix
this situation, but rather than fixing it it prevented OSDs from starting,
now because of a "big_write journal_entry was allocated over another object"
error... :-)
This change finally fixes the original issue.
Followup to 54ef2c389f
- Remove an additional data copy operation when flushing journal (should
slightly increase write performance)
- Fix a bug where new writes in the inmemory_journal=false mode could overwrite
the data currently read by a parallel read operation
- Fix degraded parity writes for EC N+K when K>1 where the bug could also lead
to an "assertion failed" error
- Fix missing journal space check for "big" writes which could lead to
"prefill_single_journal_entry(): assertion failed..." error in OSD
- Fix possible "assertion failed: next->prev_wait >= 0" in client in rare cases
- Fix missing "len" field in vitastor-disk write-journal big_writes
- Fix possible crash of a full OSD (ENOSPC)
- Fix CSI build scripts to include newest packages every time
- Fix CSI endpoint in the liveness probe manifest
