Vitaliy Filippov 57ad4c3636 Add a note about HDD, enable throttling only for hybrid OSDs 2023-07-09 12:45:11 +03:00
Vitaliy Filippov b7e4d0c9bf Fix journal dirty_start position tracking and some debug prints 
Fixes two bugs found during HDD testing :-)
1) OSD crashed with "BUG: Attempt to overwrite used offset of the journal" during
   `fio -bs=900k -iodepth=128` test with 16 MB journal
2) OSD stalled during `fio -bs=512k -iodepth=128` test with 64 MB journal

Vitaliy Filippov 161a23c966 Support reloading state when etcd says "revisions were compacted" 
Before this change, OSDs almost always died when one of the etcds was restarted,
even though the rest of them was still in quorum and the lease was still active

Vitaliy Filippov 2f999d8607 Reduce etcd memory usage 
With default --snapshot-count 100000 and GOGC=100 it easily reaches 6.6 GB
even when we only store 1-2 MB of data in it

Vitaliy Filippov b8e30608d6 Bump QEMU version to vitastor2 2023-07-01 00:55:32 +03:00
Vitaliy Filippov a612cdca47 Release 0.9.3 
- Add patch for libvirt 9.0
- Add support for Proxmox VE 8.0
- Fix compatibility of the QEMU driver with iothread (QEMU rebuilds are coming)
- Fix vitastor-cli rm-data/rm/merge hanging when some OSDs are down.
  Allow deletions in unclean cluster at the cost of some data possibly
  "reappearing" when those OSDs start back. In that case you can just repeat
  the deletion request using rm-data.
- A bunch of bug fixes for snapshots:
  - Fix snapshot reads often not working at all with snapshot chain size > 2
  - Fix optimized snapshot data merge (children to parent)
  - Fix updating of image name index key during optimized merge
  - Fix auto-selection preventing the use of optimized merge with only 1 snapshot
  - Fix incorrect CAS retries during snapshot merge
  - Fix snapshot merge progress reporting
- Fix primary_read bitmap buffers use-after-free which could lead to
  incorrect allocation map reads
- Remove /usr/local/bin path from make-etcd
- Some documentation fixes

Vitaliy Filippov 926be372fd Release 0.9.2 
- 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)

Vitaliy Filippov 4fdc49bdc7 Add another assert-type check (it does not fire, just as a safety measure for the future) 2023-06-17 00:07:22 +03:00
Vitaliy Filippov 86b4682975 Put get_trim_pos into the "critical section". Fixes rare journal corruption issue 
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.

Vitaliy Filippov bdd48e4cf1 Release 0.9.1 
- 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)
