Quick Commands

These quick commands are executed directly on the Proxmox hosts. It is advisable to connect via SSH here, as sometimes the processes for the Web GUI are switched off.

Reset MFA for local User

This command can be used to delete the MFA method of a local user. The correct user name must be specified for this. Here in the example it is "root@pam".

pveum user tfa delete root@pam

Remove Node from Cluster

ATTENTION: This removes the host from a cluster (or deletes the cluster) and also deletes all configurations and links of the other nodes. This is necessary so that the hosts do not want to connect any legacy nodes afterwards

systemctl stop pve-cluster corosync

pmxcfs -l

rm -rf /etc/corosync/*

rm /etc/pve/corosync.conf

killall pmxcfs

systemctl start pve-cluster

rm -rf /etc/pve/nodes/
