I was planning on making a Gluster Data domain to test, and found some 
great information on this page: 
http://community.redhat.com/blog/2014/05/ovirt-3-4-glusterized/
The article the author uses the CTDB service for VIP failover.  Is it 
possible/recommended to not do this, and just create a gluster volume 
on all the hosts in a cluster, then create the Gluster data domain as 
localhost:<gluster_vol>?
Theoretically, it should work - if you make sure that you have a replica 
3 gluster volume spread across 3 nodes, and these 3 nodes are your 
compute nodes as well - you should be fine without CTDB setup for 
failover and mounting as localhost.

But I've not tried this to recommend it. Maybe if others have tried it, 
they can chime in?

Btw, is there any reason you do not want to set up CTDB?
...
Thanks,
Ryan
