Objet: [PVE-User] Cluster won't reform so I can't restart VMs

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
