Vitaliy Filippov	27e9f244ec	Release 1.4.3 ... Hotfix for hotfix O:-) - "Write stall fix" was incomplete and EC write stalls could continue even on 1.4.2. Now they're finally fixed O:-) - Make monitor ignore statistics of stopped OSDs. Previously if you stopped all OSDs the last total I/O numbers would remain the same indefinitely	2024-02-09 00:29:31 +03:00
Vitaliy Filippov	8e25a28a08	Ignore down OSDs in monitor statistics aggregation	2024-02-09 00:22:36 +03:00
Vitaliy Filippov	5d3317e4f2	Followup to 1.4.2 write stall fix - sadly, the previous version was not working correctly :)	2024-02-08 19:34:29 +03:00
Vitaliy Filippov	016115c0d4	Release 1.4.2 ... - Log to systemd by default - Fix excessive autosyncs after every operation with disabled immediate_commit (introduced in 1.1.0) - Fix a possible write stall with EC due to the lack of OSD wakeup after stabilizing previous writes - Change sync operation semantics as a final fix to possible write stalls with EC and disabled immediate_commit - Sync after deleting data in CLI rm / rm-data if immediate_commit is disabled - Fix OSDs ignoring syncs & autosyncs for delete operations - Fix OSD space reporting sometimes adding garbage zeros for deleted inodes (causing extra pool/stats etcd keys for deleted pools) - Speed up monitor failover - change default etcd_mon_ttl from 30 to 5 seconds - Speed up operation retries - change default up_wait_retry_interval to 50 ms - Add patch for libvirt 9.10	2024-02-04 02:23:49 +03:00

Vitaliy Filippov	1cec62d25d	Sync only completed writes ... Should be a final remaining fix to EC + non-capacitor (non-immediate-commit) write hangs :). First it was breaking non-EC ("instantly stable") writes because they sometimes complete out of order which was leading to the following error: terminate called after throwing an instance of 'std::runtime_error' what(): BUG: Unexpected dirty_entry 1000000000001:29480000 v65540 unstable state during flush: 0x151 But it is easily fixed by scanning previous and next dirty_entries in mark_stable.	2024-01-27 15:17:22 +03:00

Vitaliy Filippov	f757a35a8d	Retry PG changes without re-running lpsolve when pool configuration and OSD tree don't change ... OSDs often change their /pg/history keys during rebalance, so monitor receives additional transaction failures from etcd if it re-runs lpsolve which sometimes may even lead to monitor being unable to apply PG changes at all until rebalance completes	2023-12-31 01:23:17 +03:00

Vitaliy Filippov	f72f14e6a7	Clear old PG states, history, and OSD states on etcd state reload ... Also add protection from etcd watcher messages being split into multiple websocket messages - I'm not sure if etcd actually does that, but it's better to have extra protection anyway. Also check that all etcd watchers are started in the keepalive routine, otherwise it sometimes tries to revive etcd watchers starting with revision=1 which obviously always fails because this revision is nearly always compacted. All these changes should fix an old rarely reproduced bug where SOMETIMES OSDs didn't react to PG config changes which was leading to offline pools on node reboot. It happened on the full reload of state from etcd.	2023-12-24 02:02:13 +03:00
