Vitastor 0.5.10 released
The version seems to be stable after this bunch of fixes :)
- Fix delete & write operation ordering during rebalance to not lose objects in the immediate_commit=off mode
- Fix a possible crash caused by very high iodepths
- Re-distribute PG primaries over OSDs that come up after a short downtime
- Allow to specify etcd URLs for OSDs with http://, do not die with a strange error if -etcd option is missing for fio
- Fix a journal flushing deadlock which sometimes occurred in the immediate_commit=off mode
- Fix a bug where OSDs could hang if the data device filled up
- Fix an allocator bug where it was unable to allocate up to last (n%64) data device blocks
- Fix monitor crash that occurred on removal of some etcd keys
- Fix a bug where PGs could remain incomplete due to incorrect PG history with just zeroes in osd_sets

Vitastor 0.5.9 released
- Fix two monitor bugs which led to objects being “logically lost” (physically present on some secondary OSDs while primary doesn’t know about it) after multiple interrupted rebalancings
- Implement “no_recovery” and “no_rebalance” flags

Vitastor 0.5.8 released
- Add heartbeats (fixes failover in case of network issues or offline nodes)
- Fix a bug where a PG could incorrectly become listed as ‘incomplete’ if historical osd_sets included a set with the the PG’s primary OSD as the only alive one
- Use osd_out_time = 10 minutes by default instead of 30 minutes
- Make monitors stick to a single selected etcd URL on start and not try to select random ones on every request - this was leading to etcd interaction errors when some etcds were unavailable

Vitastor 0.5.7 released
- 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
