Decommission Cluster

[lweidig]

We have a three node Proxmox cluster that we are in the process of decommissioning as we have a new 5.1 cluster that we have migrated the majority of the machines over to. However, for a while we need to keep one of the nodes running with one of the containers it has. But, we also want to take the other nodes and make them part of the new 5.1 cluster by wiping and reloading them.

So, can we remove ALL three nodes from the cluster and keep the one node as a stand alone for a while to run the machine that we need to leave on it. If so, what would be the correct steps? If possible we would like to keep the one node that is stand alone running through the entire process.

Thanks!

yes this is possible, see https://pve4.intern.lab:8006/pve-docs/chapter-pvecm.html#_remove_a_cluster_node
you have on to execute the delnode command on the node you want to keep, giving as paramater the nodes you want to delete
