Hello, Just started upgrading my small cluster to from 4.2.8 to 4.3.2 and endup in the situation that one of the hosts is not working after upgrade. For some reason vdsmd is not starting up, I have tried to restart it manually with no luck: Any ideas on what could be the reason? [root@ovirt2 log]# systemctl restart vdsmd A dependency job for vdsmd.service failed. See 'journalctl -xe' for details. [root@ovirt2 log]# journalctl -xe -- Unit ovirt-ha-agent.service has finished shutting down.
