1.3.9. Separate a node without reinstalling¶
Stop the corosync and pve-cluster services:¶
Firstly, stop all the cluster services.
$ systemctl stop pve-cluster
$ systemctl stop corosync
Reset PMXCFS (Proxmox Cluster File System) Status¶
Start the cluster filesystem in local mode:
$ pmxcfs -l
Delete the corosync config files
$ rm /etc/pve/corosync.conf
$ rm /etc/corosync/*
Start the filesystem as a normal service
$ killall pmxcfs
$ systemctl start pve-cluster
Remove Cluster Configuration Files¶
After killing all PMXCFS processes you must remove any remaining cluster config files for a proper re-join.
$ rm /var/lib/corosync/*
$ rm -r /etc/pve/nodes/NAMEOFPEERNODES
Note
You might want to remove the respective SSH Keys in the authorized_key file from the old nodes too.
$ pvecm add [target-ip(ring0address)]
