Hi Proxmox users,

I have a 4 node cluster. It has been in production for a few months with
few/no issues.

This morning one of my admins reported that each node appeared isolated
("Total votes:      1"). All VMs were up and unaffected. Unfortunately I
made the mistake of stopping VMs on 3 of the nodes to apply updates and
reboot as I assumed this would clear the issue. Now the scenario remains
the same but the VMs are down on 3 of the nodes and it won't allow me to
start them as I have no quorum.

No config changes were made and this cluster was fine and had quorum last
time I looked (last week).

I don't want to take the wrong action and make this worse - any advice
would be greatly appreciated!

hypervisors ar1406/ar1600/ar1601 are up to date and have been rebooted this
morning. ar1407 has not been rebooted or updated (yet) as the VMs on it are
critical.

Thanks,

Chris
