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?

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.

My storage domain still exists. However I can't activate it. The
Manage button is greyed out without clear indication as to why.
Difficult to tell what my next move should be.
Anyway to find out?

Allright.
So I followed this and configured local storage. It had some default
names that I changed. It would have been either the default name, or
one I choose. In either case it would be a different name then the
Gluster storage domain the host was a part of anyway.
Once the process completed for both hosts, I noticed the Gluster
volume storage domain was offline and the gluster volume was gone. I
can't seem to add that back in anymore. I get:
"Error while executing action DisconnectStorageServerConnection: Error
storage server disconnection"
Guessing I can't have local storage in addition to Gluster on the same
hosts and available for VM's?
Reason why I need that is that Gluster is slow but provides redundancy
and live migration. But I also wanted direct storage for VM's
requiring faster IO. So here's my sc
