As for other shared FS, this is *highly* important to make sure
Nova UID and GID are consistent in between all compute nodes. <br>
If this is not the case, then you have to usermod all instances...<br>

Hi JP,
<div>my bet is that this is a writing permissions issue. Does nova
has the right to write within the mounted directory?</div>

<blockquote type="cite">Hi,<br>
<br>
We've started implementing a Glusterfs-based solution for
instance storage in order to provide live migration. I've
run into a strange problem when using a multi-node Gluster
setup that I hope someone has a suggestion to resolve.<br>
<br>
I have a 12 node distributed/replicated Gluster cluster. I
can mount it to my client machines, and it seems to be
working alright. When I launch instances, the nova-compute
log on the client machines are giving me two error messages:<br>
<br>
First is a qemu-kvm error: could not open disk image
/exports/instances/instances/instance-00000242/disk: Invalid
argument<br>
(full output at <a moz-do-not-send="true" href="http://pastebin.com/i8vzWegJ">http://pastebin.com/i8vzWegJ</a>)<br>
<br>
The second error message comes a short time later ending
with nova.openstack.common.rpc.amqp Invalid: Instance has
already been created<br>
(full output at <a moz-do-not-send="true" href="http://pastebin.com/6Ta4kkBN">http://pastebin.com/6Ta4kkBN</a>)<br>
<br>
This happens reliably with the multi-Gluster-node setup.
Oddly, after creating a test Gluster volume composed of a
single brick and single node, everything works fine.<br>
<br>
Does anyone have any suggestions?<br>
<br>
thanks,<br>
JP<br>
<br>
