You should be able to do that with the POSIX compliant domain ... If nit, it's better to open a bug so this behaviour is investigated further.
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. 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? Thx, TK

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.

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...

Manged to reverse it through the options. Had to deactivate the custom local cluster.
Now I have my GlusterFS back and want to try and add some local storage to each host under the same DC, Cluster and Storage Domain. So effectively I will have two storage locations. One on my GlusterFS and the other on the local storage I've just defined.
Appears I can't make them coexist with oVirt. Either the host is placed in a separate cluster with local storage, or I move it back to the GlusterFS.
Appears I can't have two usable storage types under one host. Is this correct?
What I'm looking for is in the image and shared earlier.
