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

That is why I asked is anyone has started working on the doc's

Here is the feature page:

<a href="http://ovirt.org/wiki/Features/Gluster_Support">http://ovirt.org/wiki/Features/Gluster_Support</a><br>
We intend to add more documentation soon, though nothing else is
available right now.<br>

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.<br>

<blockquote type="cite">as for tips and hints, I will describe
what you need in general (very high-level):
<br>
<br>
- cluster and data-center - edit cluster and set the gluster
check box
<br>
- host side (vds):
<br>
* install vdsm-gluster package
<br>
* install all gluster-related packages
<br>
* make sure all gluster related services are fully
operational
<br>

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.
<br>
<blockquote type="cite">- create new volume (volume is a
collection of bricks which represent a collection of export
domains):
<br>
* allocate storage space on your host
<br>
* make sure this space is exposed via export (NFS) directory
<br>
* create new volume\bricks
<br>
</blockquote>
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.
<br>

<br>
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.<br>
<br>
Feel free to ask glusterfs specific questions on the #gluster IRC
channel on FreeNode.<br>

Subject: [Users] Anyone started working on the documentation
for GlusterFS and Ovirt 3.1 yet?
<br>
<br>
I installed ovirt 3.1 using the assume repo provided by
<br>
<a class="moz-txt-link-freetext" href="http://www.dreyou.org/ovirt/">http://www.dreyou.org/ovirt/</a> and it works really well. Been
a few
<br>
glitches but overall it works well. I see an interface for
GlusterFS
<br>
is
<br>
in there but no clue how to use it any hints or info been
created
<br>
yet?
<br>
<br>
Thanks
<br>
Robert
