Hello,

I need to reinstall node in cluster and i have some doubts.

I will do as recommended:
https://pve.proxmox.com/wiki/Cluster_Manager#_remove_a_cluster_node

  1. shutdown oldnode
  2. replace disks (to avoid start oldnode again)
  3. pvecm delnode oldnode
  4. install pve
  5. pvecm add IP-node-in-cluster
Anything else should I do?

maybe: rm -rf /etc/pve/nodes/oldnode/ ??


Here I found something like this:
https://tweenpath.net/remove-node-proxmox-cluster/

  • Don’t assign the local ip address of the removed node to a new node
  • Never assign the name of the removed node to a new node
But I want to use the same IP and name. Can I?
 
As far as I am concerned you have to remove the outdated SSH-Hostkeys that every other pve node in the cluster holds. Otherwise you well get those typical SSH Security Breach warnings when connecting to the other pve nodes.

Thanks for the answer.
Yes, I remember about the ssh keys.

I am most afraid of this:

If you are using HA you may encounter stale lrm-status entries in the HA-status. But besides that we did not encounter any further problems with this practise.
