Remove one from the cluster, then wipe it and reinstall a clean Proxmox with the new name and new IP-address, and add it to the cluster. Do the same for the other node. Please note that a two-node cluster does work when one of the nodes is missing if there is no Q-device (or third vote).I would like to rename these nodes (currently "proxmox" and "joanine"). What is the correct way of doing this?
I don't fully understand the question. Nodes should be empty when adding to a cluster, but can't you migrate the VMs/CTs between the current nodes? And if you rename in-place, I don't see why. It's always wise to make backups of the VMs/CTs before making changed to the cluster (which you can restore later).Thanks, it sounds like I cannot keep my current VMs/containers if I want to rename the host. Is that correct (must be "empty")?
See the wiki linked above:I would just like to change the names of the physical machines.
This must be done on a empty node.
So you then have to remove all the VMs/LXCs on the node you want to rename.If your node is in a cluster, where it is not recommended changing its name
