• v1.0.0 6acf562e01

    Release 1.0.0 Stable

    vitalif released this 2023-07-29 18:57:19 +03:00 | 27 commits to master since this release

    New features:

    • Data and metadata checksums!
      • Metadata checksums are always used with new disk format
      • Data checksums can be turned on with --data_csum_type crc32c for new OSDs
      • Checksum block size can be configured
      • inmemory_metadata now also affects keeping checksums in memory
    • Linux page cache I/O caching support which can be enabled separately for
      data, metadata (including checksums) and journal (O_SYNC instead of O_DIRECT)
    • Details here
    • Backwards compatibility is preserved, you can use new OSDs with old disks

    Release also includes bug fixes from 0.9.6.

    0.9.6 is moved to "-oldstable" repositories and will be available for some additional time.

    Release 0.9.5 Stable

    vitalif released this 2023-07-21 00:04:41 +03:00 | 81 commits to master since this release

    A hotfix to 0.9.4 containing only one bugfix: 100% CPU usage in the new QEMU
    driver caused by the lack of eventfd reset on io_uring event handling :)

  • v0.9.4 1c10430ae1

    Release 0.9.4 Stable

    vitalif released this 2023-07-19 02:50:30 +03:00 | 84 commits to master since this release

    • Improve QEMU driver performance by integrating io_uring in it (up to 1.5x total iops improvement)
    • Fix QEMU driver deadlocks which started to reproduce in qemu-img after iothread fixes
    • Fix vitastor-cli status reporting more etcds than actually exists (fix etcd address duplication in config on reload)
    • Fix vitastor-cli ls crashing on inodes in non-existing pools
    • Delete old garbage /pool/stats/ keys for non-existing (deleted) pools
    • Reduce memory usage of etcds initialized by make-etcd script
    • Fix OSDs almost always crashing on etcd restart due to "revisions were compacted" (support reloading state from etcd)
    • Fix a crash and a stall possible mostly in HDD setups with small journal and big (512k, 900k) random writes
    • Add notes about HDDs to documentation. You are officially allowed to use HDD-only Vitastor with HGST/Toshiba/EXOS :)
  • v0.9.3 a612cdca47

    Release 0.9.3 Stable

    vitalif released this 2023-07-01 00:25:58 +03:00 | 111 commits to master since this release

    • 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
  • v0.9.2 926be372fd

    Release 0.9.2 Stable

    vitalif released this 2023-06-18 19:44:33 +03:00 | 136 commits to master since this release

    • 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 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)
  • v0.9.1 bdd48e4cf1

    • 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)
  • v0.9.0 3b4cf29e65

    • 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)

    Release 0.8.9 Stable

    vitalif released this 2023-05-14 01:25:09 +03:00 | 195 commits to master since this release

    • 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
  • v0.8.8 ab615849d6

    • Fix OSDs re-peering PGs infinitely with a big number of PGs (reproduced in test_add_osd)
    • Fix another variant of flusher sync-waiting stall (reproduced in test_write)
    • Fix other tests in tests/ (will add them to Gitea CI soon)
    • Add patches for QEMU 6.2-8.0
