SOLVED - 3-node cluster, node failed

[chrisj2020]

Hi there,

I have a 3-node NUC10 cluster, I've had a hardware failure on the first node, and my plan is to replace it. All CT and VMs have been moved onto the other nodes using backups. But I do not have a backup of the failed Proxmox node itself. My thinking was to just re-install Proxmox on this node (replacing the failed hardware), and then re-join it to the cluster. But I have read about potential issues if I try to re-join a node to a cluster with the same name.

What would you recommend?

You can follow the admin guide: https://pve.proxmox.com/wiki/Cluster_Manager#_remove_a_cluster_node

It covers your situation:

At this point, you must power off hp4 and ensure that it will not power on again (in the network) with its current configuration.

If, for whatever reason, you want this server to join the same cluster again, you have to:...
