Hey everyone!

New here and working through some first time homelab kinks.

I had created a second node on an HP z8g4 workstation, and struggled to keep it from crashing. Turns out that the power management 'idle mode' in the HP Bios doesn't work with Proxmox very well. I found this out after many flip the table moments, where I recreated the node from scratch with the same issue. In doing so, I removed the 2nd node in my data center.

Unfortunately it still shows under the dropdown on the left. How do I remove this completely so that I can re-add the node that is now working without getting errors for the same device and ip?

What is the status of the cluster (pvecm status) seen by the remaining node (homelab)?

Generally, you need to clean up a bit:
The configuration files for the removed node will still reside in /etc/pve/nodes/hp4. Recover any configuration you still need and remove the directory afterwards.

(The path, specifically the node name (hp4) in it, is an example and you need to adapt it, of course.)

For re-adding, keep in mind:
If, for whatever reason, you want this server to join the same cluster again, you have to:
  • do a fresh install of Proxmox VE on it,
  • then join it, as explained in the previous section.

After removal of the node, its SSH fingerprint will still reside in the known_hosts of the other nodes. If you receive an SSH error after rejoining a node with the same IP or hostname, run pvecm updatecerts once on the re-added node to update its fingerprint cluster wide.

This was it!! Migrating to '/etc/pve/nodes' and removing the directory immediately removed the reference to the node on 'Server View'.

Thank you so much for your help!

I'll look to add my node back later this week.
