No.  I got close to getting it to work but I was having issues with 
Fedora 17 crashing every 10 to 12 hours and that might have been why I 
couldn't get that last 1%.  I did pretty much the same steps to get 
really close to getting the glusterfs structure to work.

1) Mount the volume outside of ovirt. mount -t nfs 
ipofonenode:/volumename /temp/share/name or mount -t glusterfs 
ipofonenode:/volumename /temp/share/name
2) chown -R 36.36 /temp/share/name
3) umount /temp/share/name
4) Added a new Postfix gluster fs domain with the Path of: 
localhost:/volumename and the type of glusterfs.

It mounted fine but I couldn't get it to activate.

Try editing file /etc/nfsmount.conf on each node and add the following.

[ NFSMount_Global_Options ]
Defaultvers=3
Nfsvers=3
