after adding HA - pve nodes rebooting randomly every few hours.

[infonancial]

Hi,
Since we applied the HA configuration in ProxMox 6.3-3 . The PVE nodes start randomly rebooting every few hours with no any reason. We reverted the setup, removing HA and quorum groups and system back to its normal state, however without HA. System has 5 PVE nodes. Please, advise.

Most likely, your network is not reliable ...

Hello Dietmar,

Is there a way to check for network related issues in the logs? What exactly are we looking for?
The logs get's reset after the nodes restart. We do not have any logs of the proxmox from before the restart takes place. Is there a way to disable logs from being reset?

You are looking for corosync messages (quorum related)

You need to enable persistent logging with:

mkdir /var/log/journal
systemctl restart systemd-journald
