After I upgraded one of my Ovirt hosts from 4.4.0 to 4.4.2 using yum become a faulty host for the cluster. I tried to uninstall the upgrade but that didn't help. After checking the status of the Host I found out that the "ovirt-ha-agent" is not starting due to changes in the LVM setup from the upgrade. Is there any way to move back the LVM setup as was before the upgrade? I am sending you the LVM setup before and after the upgrade:
