Vitastor 0.5.7 released

2021-03-08

  • Fix multiple bugs leading to OSDs sometimes being unable to correctly activate PGs when a lot of PG peering events occurred in a small amount of time
  • Fix a bug where OSDs could list incomplete object versions during peering. The bug manifested with “local rollback operation failed” messages in OSD logs
  • Fix a bug where misplaced chunks for degraded and incomplete objects were not removed from extra OSDs during recovery
  • Fix incorrect PG history configuration resulting in OSDs being unable to find some of the objects after a PG count change
  • Simplify block layer write ordering logic
  • Avoid extra data move when a lot of OSDs are first stopped for long time and then restarted
  • Fix incorrect degraded & misplaced object statistics after a completed rebalance
  • Fix incorrect usage of pg_minsize instead of the minimal possible object chunk count in EC pools
