- Measure and report scrub I/O statistics in vitastor-cli status
- Make aggregated statistics in vitastor-cli status much smoother
(first derive, then sum instead of first summing and then deriving)
- Fix an old rare bug leading to journal corruption
(try to use scrub if you think you're affected...)
- Do not start EC PGs without at least <data chunks> OSDs in each old set
(prevents spurious read errors with EC during reconnections/restarts)
- Fix failed assert(!scrub_list_op) on OSD restart with pending scrubs
- Fix future planned scrubs not starting because of incorrect time comparison
- Build packages for Debian 12 (Bookworm)
The consequence of this issue was that in some very rare cases (only reproduced
under load in CI when running 4+ tests in parallel) small write data written to
journal could overwrite journal entries.
Also add an assert-type safety check to be able to catch this issue in the
future again in case of a regression.
- Fix "Client XX command out of sync" messages sometimes happening on OSD reconnections
- Fix a bug where EC reads parallel with writes to the same object failed with -ERANGE error
- Slightly reduce the amount of metadata writes during journal flushing
- Correctly unmap NBD volumes when Proxmox forces map_volume use (with SWTPM and maybe some other cases)
New features:
- Scrubbing! Check documentation: [auto_scrub](src/branch/master/docs/config/osd.en.md#auto_scrub)
- Document online-updatable configuration parameters
Bug fixes:
- Fix NaN during PG optimisation if there are nonexisting OSDs in node_placement
- Fix monitor crash on pool deletion
- Clear journal_device and meta_device before initialising the next OSD in automatic mode
- Sync unsynced deletes before overwriting them with a lower version
(reproducted mostly/only after scrubbing)
- The tests are now stable and run in a CI system based on Gitea CI
- The release includes final bug fixes for EC:
- Implement missing EC recovery of allocation bitmap when built with ISA-L
- Fix broken snapshot export with EC (allocation bitmap reads were giving incorrect results previously)
- Also fixed bugs manifesting under heavy load:
- Fix monitor possibly applying incorrect PG history on retries
- Fix monitor incorrectly changing PG count when last_clean_pgs contains less PGs than the new number
- Allow writes to wait for free space again, but now correctly (previously dropped in 0.8.2)
- Fix a rare segfault in client (handle client stop during incoming stream handling in 1 more place)
- Make monitor correctly handle etcd connection errors - it could die instead of connecting to another etcd
- Fix OSD rarely being unable to report PG states after a PG was taken over by another OSD
- Fixed return code for incomplete EC objects (now EIO) and made cluster client retry this error
- Made other small changes for tests: timeouts, nice/ionice for etcd, waiting conditions, NBD device checks and so on
