Due to upgrading the ovirt self-hosted engine I had the cluster in
global maintenance mode. I was not aware, that issuing
shutdown -r now within the engine VM will in fact not reboot the engine, but will only make it shutdown. After reading the engine troubleshooting guide once again I now know better.
For reasons unknown the root password for the node the engine is running on, is unknown. Thus I cannot get into the node via shell or web interface.
So... If I'd deactivate the global maintenance mode on a different node of the cluster that is capable of running the engine by issuing a
hosted-engine --set-maintenance --mode=none, would this trigger a restart of the hosted engine ?
The cluster is running ovirt 4.1.9.
