We do have a limitation currently that if you use multiple FQDNs, oVirt
cannot associate it to the gluster brick correctly. This will be a problem
only when you try brick management from oVirt - i.e try to remove or
replace brick from oVirt. For monitoring brick status and detecting bricks
- this is not an issue, and you can ignore the error in logs.

Adding Ramesh who has a patch to fix this .
