I haven't tried the POXIS compliant domain but from what I recall and remember happening, I couldn't bind a host to more then a single storage domain. I could be wrong but I couldn't select more then a single storage domain a host could be associated with.
"Any POSIX compliant file system used as a storage domain in oVirt must be a clustered file system, such as Global File System 2 (GFS2), and must support sparse files and direct I/O. The Common Internet File System (CIFS), for example, does not support direct I/O, making it incompatible with oVirt." Guessing this might not work if I have a Local LUN that's XFS or EXT4?
So it was either Local storage or GlusterFS storage, but both couldn't be bound to a single host.
Does oVirt have the facilities to test this out to see how it should be done?

I'm not sure, but you can try with replica 1 gluster volume. Later that gluster volume can be changed to replica 2 arbiter 1 or even better replica 3 volume.
Now that I see this I'm not sure we're on the same page.
Thinking this might clarify a bit better. Let's take this scenario, assume gluster is working perfectly:
HOST01 4TB Local LUN /dev/sdb 4TB Gluster FS (brick w/ host02,03) /dev/sdc
HOST02 4TB Local LUN /dev/sdb 4TB Gluster FS (brick w/ host01,03) /dev/sdc
HOST03 4TB Local LUN /dev/sdb 4TB Gluster FS (brick w/ host02,01) /dev/sdc
For each host I need the local LUN to be available for VM's with the GlusterFS storage that's distributed across all three nodes.
However, when I tried to add a local LUN, the host was removed from the storage domain rendering it unavailable. Now when I took out the local LUN, I was able to readd that host to the GlusterFS storage domain.
So it appears I can't add a local LUN when a host is already participating in a GlusterFS storage domain.
Cheers, TK

I take it then theres no way to do so without NFS?

You can create an NFS on that host and export to itself that local storage...
