New features:

  • Implement client writeback cache
  • Add the third I/O mode: O_DIRECT|O_SYNC (good for Optane)
  • Reduce load on etcd by splitting OSD lease and statistics reporting intervals: etcd_stats_interval (default 30 sec)
  • Make MON automatically filter OSDs by layout (block_size/immediate_commit/bitmap_granularity) to prevent "refusing to start PGs of this pool" errors on misconfiguration
  • Support running fio benchmarks on systems without io_uring
  • Make QEMU driver compatible with QEMU 8.1
  • Document usage of vhost-user-blk

Bug fixes:

  • Fix resizing disks in QEMU driver (for example, in Proxmox)
  • Fix "unexpected result" in Proxmox driver by making CLI flush output on exit
  • Remove unneeded block_size mismatch warnings on pools without matching PGs
  • Fix possible segfault in vitastor-cli ls -l (usually with deleted pools)
  • Fix QEMU driver compatibility with systems without io_uring
  • Fix monitor eating 100% CPU when etcd is down (caused by infinite retries)
  • Fix potential incorrect write processing with snapshots (not caught in tests but could probably lead to client hangs)
  • Fix buffer insertion in cluster_client (not caught in tests but could probably lead to incorrect writes in rare cases)
  • Fix rare OSD crash during sync operation processing
  • Fix a reenterability issue in cluster_client not reproducible in QEMU/fio, but reproducible with the currently developed K/V database implementation
  • Fix deletion of the first modified object - OSDs could crash if you modified the same object a lot of times, then deleted it, and then modified it again
  • Fix the fio_sec_osd test tool
