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. I would start by browsing tohttp://www.gluster.org/ and read about the underlying technology (glusterFS, admin guide is good place to start). 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. as for tips and hints, I will describe what you need in general (very high-level): - cluster and data-center - edit cluster and set the gluster check box - host side (vds): * install vdsm-gluster package * install all gluster-related packages * make sure all gluster related services are fully operational 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. - create new volume (volume is a collection of bricks which represent a collection of export domains): * allocate storage space on your host * make sure this space is exposed via export (NFS) directory * create new volume\bricks 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.

adding Shireesh\Daniel Hi Robert, afaik, there is no official documentation that show's how to work with glusterFS using oVirt since its too new and we are in early integration phases (shireesh, correct me if i'm wrong).
