Yes, exactly. It's more for the reason that the removed node still thinks that it is part of the cluster and has still access to the cluster communication (through the '/etc/corosync/authkey'). So re-installing works fine. You could also separate it without re-installing, see: https://pve.proxmox.com/pve-docs/chapter-pvecm.html#pvecm_separate_node_without_reinstall Here I recommend that you test this first (if the target is anything production related) - e.g. in a virtual PVE cluster (PVE in VMs). cheers, Thomas _______________________________________________ pve-user mailing list [email protected] https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user
