Dont. just dont.
What you can do, if you REALLY must, is to evict nodes one by one, reinstall (do NOT skip this part), and read. see https://pve.proxmox.com/wiki/Cluster_Manager#_remove_a_cluster_node
yes, you can follow the link in that link but even they don't recommend doing it. screwing up here can lead to data corruption.
I've done it successfully in our lab a few times. That said, if someone manages to do it incorrectly and cause some sort of cluster wide issue - it wouldnt surprise me.
PS if this was a production cluster and I had to do this, I would build a virtual cluster matching the config and try there. Perfect use for a cluster of hypervisors
