Reinstall one of the nodes

[gbetous]

Hi all,

I'm planning to reinstall one of the nodes of my cluster to give it a bigger SSD for the base system (can't add one, I have to switch it).

What I'm planning to do:
- backup all VMs (there is a proxmox backup in the cluster)
- pvecm delnode
- reinstall proxmox with same IP, same name... (is there a way to copy the full configuration ?)
- pvecm addnode
- restore VMs

Quorum is not an issue with this node down (already tested).

Do I miss anything ? This is not at all a critical situation (kind of lab cluster), but I want to do it as it was...

Thanks !

- reinstall proxmox with same IP, same name... (is there a way to copy the full configuration ?)

Make sure NOT to copy too much of the configuration. The manual warns against restarting a node with the same configuration:

As mentioned above, it is critical to power off the node before removal, and make sure that it will not power on again(in the existing cluster network) with its current configuration. If you power on the node as it is, the cluster could end up broken, and it could be difficult to restore it to a functioning state.

Thanks for pointing it out !
