Hey all,

Hope this is an easy one; just want to know if I'm about to experience a learning moment before I do something silly.

When I installed ProxmoxVE to a node, I gave it the wrong IP. I changed it following the installation. I then installed PVE to a second node (and got the IP right). I then created a cluster on node 1, and joined node 2 to the cluster.

Node 1 can perform migrations to node 2, and can view/modify its config without issue. Node 2 cannot do the same to node 1. When looking at task output, it's still trying to use the old, wrong IP, despite it being changed and not present anywhere. Running a grep on /etc I found the old IP to be present in /etc/pve/.members and /etc/pve/priv/known_hosts.

I know those are mostly meant to be read-only. Is there a proper way to change them? Can I just edit those files?
 
Well, in typical fashion, as soon as I ask, I figure it out on my own.

I'm blind and didn't notice that the old IP was still present in the hostfile (as well as being visually present in the datacenter summary). Changing that and rebooting it got everything working.
