Files to backup in case of upgrade failure

[davemcl]

What files need to be backed up so that I can restore a node back to its working cluster state.

If I restore corosync.conf & authkey will the cluster replicate everything else?

Would also need /etc/pve/priv/authorized_keys

Then a systemctl restart corosync pve-cluster ?
