I'm trying to create a cluster, but I'm having some difficulties. First of all, the IP 192.168.1.215 was a previous node before it was removed, to be replaced with a node of the same IP. When I try to add node .216 to it, with "pcevm add , I get "unable to copy ssh ID" - No password prompt or anything. So then, I used pvecm create to make it a cluster, in hopes it would magically fix things. Now, I get "authentication key already exists" instead. I have no idea where to go from here. It's full on Proxmox 4.
