That is why I asked is anyone has started working on the doc's
Here is the feature page: http://ovirt.org/wiki/Features/Gluster_Support
We intend to add more documentation soon, though nothing else is
available right now.

Read though there doc's but wasn't sure how much needed to be done
using native glusterfs tools and how much is done using ovirt engine
because of the fact it was recently integrated means there are still
likely holes in the process.
Most of the features mentioned in the feature page, except async tasks
(rebalance volume, migrate brick) and bootstrapping changes are
currently available from UI and REST api. You should run engine with the
option "InstallVds" set to false and SSL disabled (on both engine and
vdsm). When creating clusters, make sure you select the checkbox to
enable gluster services, and always add hosts to such clusters from UI only.

Didn't see vdsm-gluster when I built the nodes but when I looked for
the package it was there. Already had all the glusterfs services
running.

This is where I am confused. glusterfs supports 3 methods of exposing
the cluster. Is ovirt using the NFS or the native(fs) method? If it
is NFS why the interface for bricks? Wouldn't you just create a giant
nfs share? This is the area I am most confused with and looking for
hints on.
To be more precise, glusterfs supports 3 methods of exposing a *volume*,
and not cluster. A cluster can contain a number of volumes. In Gluster
terminology, Bricks (server:directory) are building blocks of a
"volume". Volumes can be exported using native (GLUSTER), NFS or CIFS
protocols, though only GLUSTER and NFS are available from the UI for
now. A volume need not necessarily have bricks on all servers of the
cluster. If you want one giant NFS share spread over all servers of the
cluster, you'll have to use one brick from each of the servers when
creating the volume, and then export the Volume via NFS.
Feel free to ask glusterfs specific questions on the #gluster IRC
channel on FreeNode.
