pve-cluster restart

[SamTzu]

For some reason one of our clusters "breaks up" every couple of days.
We have to do pve-cluster restart on several nodes and then it's fixed again for a few days.

/etc/init.d/pve-cluster restart

What could cause this? I think the "main" node has a faulty NIC that could cause problems during backup.
But if one node gets cut of, that should not break the cluster?

I just remembered. This first node had a IP address change after it was created.

and hint in the logs?

 

[dennis1]

Check if the IP match with de hostname in /etc/hosts on both nodes.

proxmox1 has a correct IP address in host file and has been rebooted afterwards.
Only thing that the logs revealed was a loss of connection to the NAS server during one of the backups.
One of the backups is somehow always 2 times too-big. It's supposed to be ~30Gb but it is always ~60Gb.
But that is another matter I think and not really related.
