I had the problem using Fedora 17 using native posix fs mode.
In your blog, I have not found any articles on ovirt. Last post by

I am still finishing up my blog post I haven't posted it yet It is
still a draft. Getting closer. I am waking though the steps in a
fresh install to make sure I am not missing any steps.
In any case, if my situation has been reproduced and you - a sign of
a bug that needs to be identified and transferred to the correction
of the developers.
When it was happening to me it looked like a locking problem. Since I
was having other problems with Fedora 17 I rebuilt everything under
CentOS 6.2 with zero problems. However I learned a few little tricks
that might have helped make it not happen.
In what configuration you have installed gluster?
Both Posix FS (Native mode) and NFS using localhost:/volume format
over a 1G network.
Its performance depends on the choice of operating modes.
In both cases provisioning was really slow. I found the NFS ran
better of the two from research it was likely because NFS shares are
by default cached native gluster fs isn't. However if you are using
Fedora 17 with the latest kernel and it is stable for you Posix FS is
likely much faster since fuse supports direct IO now. Also a faster
network could make a real difference.
Thanks for your help
Thanks

I am writing a blog post on the steps I did to get it all working. I
have done it 3 times without issue. I am doing it a 4th time well
writing I had a lot of problems with Fedora 17 but that was because
of Fedora 17 not oVirt. Once I switched over to CentOS 6.2 and his
build #8 everything just started working and working very well. On
CentOS 6.2 I found that NFS is faster then native mode because of
Caching over my gigabyte network but both are slow well provisioning.
Thanks

I sent the logs vdsm, but they do not specify any error.
How do I know what is going wrong?
I would be grateful for any ideas.
I was just able to repeat the issue. If you only have one node active
it will activate and work fine. But if you have 2 or more hosts / nodes
it will just round robin though the hosts with each host contending on
each round. I don't have that problem with NFS shares.
Thanks

I had the same problem with Fedora 17. I killed everything and
started from scratch using centos and it works fine. I am wonder
if there is the an issue with the Direct IO support that was
added recently to Fedora 17.
Thanks

I can not mount a volume cluster with two servers.
In a separate node activation, gluster volume installed
successfully.
For simultaneous operation of two servers with gluster volume
ovirt constantly switches SPM, without giving an error.

Are you having problems creating a Volume or mounting the volume?
Thanks

I checked the manual work gluster from two hosts.
Mounting is working correctly.
However, in a pair of hosts refuse to work (connection
error storage).
Individually, each of their hosts working correctly,
and connects with gluster storage.
I have to manually mount gluster storage? In which folder?
You can write that how-to add a server to an existing
cluster of gluster?

Hi.
I use ovirt 3.1 and gluster storage.
I added the two servers in a cluster.
And faced with the problem of their joint work with
gluster storage.
Storage not initialized, although on one server
working successfully with gluster storage.
Vdsm log an attachment
(vdsm-6.log – node -1)
(vdsm-7.log – node -2)
You have to tweak you ipstates table to allow glusterd to
talk to the other box glusterd and you have to manually
peer the systems together.
