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
