Updated by Nathan Cutler almost 6 years ago
https://github.com/ceph/ceph/pull/19031 We periodically see the address of a monitor printed at INFO level (this is coming from the timecheck code) We see the monmap printed each time a new mon goes active (can downgrade this to DEBUG) After a mon is killed the new leader will claim HEALTH_OK before shortly afterward recognising the MON_DOWN condition, like this: <pre> 2017-11-08 09:45:43.978830 mon.a [INF] mon.a is new leader, mons a,c in quorum, ranks 0,2 2017-11-08 09:45:43.981497 mon.a [INF] overall HEALTH_OK 2017-11-08 09:45:47.545074 mon.a [WRN] Health check failed: 1/3 mons down, quorum a,c (MON_DOWN) </pre>
