[ovirt-users] after host cert expiry, unable to remove the nodes from the cluster, all nodes are down

Hi Team After SSL certificate is expired between Host and Manager, all the hosts are in unresponsive state in ovirt egine, expect one in unassigned state.. After manually renewed cert via ssh, as we need to remove and re-add the node to engine, we are trying to put the host into maintenance mode but failed with below error Error while executing action: Cannot switch Host to Maintenance mode. Host still has running VMs on it and is in Non Responsive state. Alternatively after a host reboot, when we try to do confirm host has been rebooted option, getting below error. Error while executing action: Cannot perform confirm 'Host has been rebooted'. Another power management action is already in progress. Need a help on how do we remove the node from ovirt engine and add it back..
