Proxmox cluster with two nodes with identical names

[thimplicity]

Hi everyone,
I have 2 proxmox servers that serve different funtions. One is my router and hosts essential services (e.g. homebridge) and one is for other services like plex. I would still like to create a cluster (to benefit from VM migration etc.) and have the essential one as main and the other one as second. Both have the name "pve". Is that a problem when creating the cluster? I read renaming them needs to be done with an empty server, so this does not seem to be an option for me.

Thanks!

Please don't because if one system is not running/reachable, the other also won't work. You need a third vote (or node).
According to the Proxmox roadmap, you can migrate between separate Proxmox installations (but not via the GUI).

That's not how a Proxmox cluster works. There is no main, each node has the same status (as long as it has quorum with enough other nodes).

I think it will be a problem. Renaming a Proxmox installation is also very error prone. And you should not have VMs on the Proxmox installation that you want to add to a cluster, as I understand it.

Thanks, this is helpful feedback. I read that you can give 2 votes to one nodes in a cluster or use a qdevice.

Correct, going back to my previous comment, main would mean the node with two votes.

I have not found that anywhere? Can someone else confirm this as well?
