This 2nd post is about the next type of flapping osds we encountered
after upgrading. We started to see osds going down with this in 'ceph -w':
2024-08-01 12:02:57.437135 mon.cat-hlz-stor001 [INF] osd.479 marked down
after no beacon for 902.637005 seconds
2024-08-01 12:02:57.468372 mon.cat-hlz-stor001 [WRN] Health check
failed: 1 osds down (OSD_DOWN)
We have the beacon interval set to 300. To fix this we tried:
- restarting osds
- restarting mons
- ntp tidyup
- restarting mgrs
However it is still happening. Poking around in the osd and mon logs we
did see some lines that hinted that the mon might be listening for
beacons using v1 - which could be broken (see part 1). Hence restarting
them again. This did not have any effect.
Apart from enabling the v2 msgr we have not altered our Luminous config
for Nautilus, are we missing something?
Regards
Mark
