Hello community,
we are on ceph 13.2.8 - today something happenned with one MDS and cephs
status tells, that filesystem is degraded. It won't mount either. I have
take server with MDS, that was not working down. There are 2 more MDS
servers, but they stay in "rejoin" state. Also only 1 is shown in
"services", even though there are 2.
Both running MDS servers have these lines in their logs:
heartbeat_map is_healthy 'MDSRank' had timed out after 15
mds.beacon.mds2 Skipping beacon heartbeat to monitors (last acked
28.8979s ago); MDS internal heartbeat is not healthy!
On one of MDS nodes I enabled more detailed debug, so I am getting there
also:
mds.beacon.mds3 Sending beacon up:standby seq 178
mds.beacon.mds3 received beacon reply up:standby seq 178 rtt 0.000999968
Makes no sense and too much stress in my head... Anyone could help please?
Anton.
