correcting improperly networked cluster

[borepstein]

Hello all,

We have cluster where one of the servers was at one point configured with an incorrect IP address and enrolled into a cluster (2 servers in cluster) under an incorrect IP address. I am wondering now how to fix this without losing operational capacity in the process.

For example, is it possible to migrate all the VM's to once server, fix PVE on the other and then re-enroll it into the cluster? Or is it possible to fully disassemble the cluster, repair the defective server and then re-create the cluster with proper configuration?

Any recommendations will be much appreciated.

Best regards,

Boris.

Here I found a related discussion which seems to indicate that while creating a cluster on top of a stand-alone node is easy, the reverse would be anything but:
