Accidently deleted /etc

[Dumb]

Hi.
I accidently deleted /etc on the second host in a 2 host proxmox cluster (no HA active).

Short description (from my memory):
PVE1 installed, 2 physical disks, ZFS RAID1
Created cluster
PVE2 installed 2 physical disks, ZFS RAID1, and joined to cluster
4 VMs installed, configured and prepared for production use.
Replication with default settings activated
nfs installed and configured on both hosts and backup job created (VMs on PVE1 backed up to nfs on PVE2 and VMs on PVE2 backed up to nfs on PVE1)
Proxmox backup server installed and backup of all VMs done to external site

Migrated all VMs to PVE1
Deleted /etc on PVE2

Can´t login to proxmox WEB GUI
Can ssh from my workstation to PVE1

Both hosts are now shutted down

To wipe and reinstall PVE2 is fine but how to "revert" PVE1 to a single host, no cluster state again or a single host in the broken cluster again?

If we need to wipe and reinstall both hosts will we be able to use backups from nfs or backup server and restore in to the new cluster?

Kind regards \\Mike

The remaining node is now basically in this scenario https://pve.proxmox.com/pve-docs/pve-admin-guide.html#pvecm_separate_node_without_reinstall

Follow the steps on this node until the pvecm delnode command (which would be on a node still in the cluster)
