A few of my hosts Keep Fencing.

How can I troubleshoot this. Seems 2 of my servers in a 4 node CEPH cluster keep bouncing.
I cannot seem to find anything in the syslogs. Seems to be only the same 2 machines.

Hello sourceminer

How can I troubleshoot this. Seems 2 of my servers in a 4 node CEPH cluster keep bouncing.
I cannot seem to find anything in the syslogs. Seems to be only the same 2 machines.

Are these just CEPH nodes or Proxmox nodes too?

Even you wrote "cannot ... find anything in the syslogs": post a sequence of such an event and we may see more .....

How often does this happen?

Try do exchange the power connection between the "good" and "bad" servers - it cannot be excluded that the issue is caused by problems in the power delivery (missing or unstable ground connection, unstable tension etc.)

Kind regards
