Description

Link to the job - https://pulpito.ceph.com/rishabh-2024-03-27_05:27:11-fs-wip-rishabh-testing-20240326.131558-testing-default-smithi/7625621

This failure on surface looks similar to https://tracker.ceph.com/issues/57656 but isn't because the failed job for this ticket doesn't contain following lines -

Instead it contains following lines -

Just because the mds.b and mds.c daemons were barked by the watchdog and then killed all the daemons and at the same time unmounted the ceph-fuse daemon.

For example for the mds.b, it sent the beacon with seq 9, but didn't get any reply and then sent a new beacon with seq 10:

But with the beacon with seq 10 the MON just replaced the mds.b.

While from the mon.b logs it just received the mds.b's beacon seq 9 after around 2 seconds later. The mds.b's beacon message should be stuck somewhere due to some reasons:

But the MON will only allow 60s and then will assume the mds.b is dead and then will replace it:

While in the MDS side it will allow the interval of 4s, please see mds option mds_beacon_interval.

From the logs I couldn't know exactly why the beacon message was stuck. But for the option mds_beacon_interval we need to do a fix IMO ?

Raised one PR to add more debug logs in the protocol code: https://github.com/ceph/ceph/pull/57857.
