You can provide the mount options from the ovirt front end, while
creating the storage domain.
I'm assuming you selected Storage type as "Data/Posix compliant FS" or
"Data/GlusterFS". There is a "Mount Options" field where you can
specify
"backupvolfile-server=<list of comma separated host names>". These are
the other nodes on which the volume is replicated. So if the primary
server is down, it will try to use the other servers to get the volume
file. This is useful only when the virt server is first trying to mount
the gluster volume.
Ideally, if your virt hosts are UP, when one of the gluster servers
goes down, your storage domain should be UP. (even without the
backupvolfile-server option)
I'm not very familiar with oVirt Storage Domain ,so someone from the
oVirt storage team should be able to guide you further.

Aah..ok. Maybe the/"/////backupvolfile-server" mount option would
help you?
[+ Allon] for storage domain issue.

What is

# gluster volume info - should give you this

If you're replicating the volume across 3

<div>Hi I am trying to

have followed examples
on setting up Ovirt and
they have helped me so
far, but not the end

for.<br>

</div>
I am running 3 HP micro
servers and 2 HP DL360 G5<br>
</div>
The 3 micro servers are my
glusterfs storage and have
been provisioned for virt
storage.<br>
</div>
The 2 DL360 are my processing
machines.<br>
<br>
</div>
Now my 3 gluster hosts are in one
cluster, the volume is in up
status and has been provisioned
for Virt Storage. But the problem
is that my mount point is directed
to one server, so when that server
goes down, the volume storage
domain goes down. I am not sure
whether there is a way of mounting
it by a "volume identity", so when
a server goes down the storage
domain stays up.<br>
<br>
</div>
With my 2 processing hosts, I have
them in one cluster, but I have not
gotten any where with this, as I
want the Virtual machines to use the
gluster volume as storage but use
the processing hosts hardware for
processing power. <br>
<br>
</div>
I would appreciate any assistance.<br>
