The system was upgraded while VDO service was running which was causing mounting device issue.

In lsblk command output there was no filesystems were not mounted, and the LV is not available.

The dependent oVirt bug is ON_QA and moving this bug to ON_QA to enable verification

Comment 6 SATHEESARAN 2018-10-15 01:58:38 UTC

Tested with ovirt-engine-4.2.7.2 

When the host is moved in to maintenance by stopping the gluster services from RHV Manager UI, the gluster and VDO services are stopped.

When the host is activated, gluster and VDO services are started again
