I'm currently setting up an ovirt cluster and so far it looks<br>
good. I<br>
like the integration with Foreman <a href="http://theforeman.org/" target="_blank">http://theforeman.org/</a> .<br>
<br>
I would like to use Ceph / rbd for my storage. I saw some<br>
mention of<br>
patches coming in May, but I did not find any new posts.<br>
<br>
What is the status of this work? Is there some patches I can<br>
try out?<br>
I have a working Ceph cluster and a working ovirt cluster, I<br>
just need a<br>
way to bring them together.<br>
<br>
Thanks, JOSH<br>
<br>
<br>
<br>
I don't remember any active work on this right now (for sure nothing<br>
like the gluster integration being done).<br>
but iiuc, ceph provides posixfs support - did you try creating a<br>
posixfs based storage domain?<br>
(you would need a "full" host (not ovirt-node) to install ceph<br>
client components on).<br>
<br>
Thanks,<br>

I am doing my work on Fedora 17 hosts, not ovirt-node, since I know this<br>
will need more OS support.<br>
<br>
There are a few different Ceph filesystems. But the posix based one is<br>
the least ready for production. The rbd filesystem is integrated into<br>
qemu and libvirt is the most suited for VM images.<br>
<br>
Are the Gluster patches available? I would like to see what that<br>
feature looks like and if I can modify them for Ceph.<br>
If there is a better filesystem to investigate please let me know.<br>
<br>
Thanks, JOSH<br>

gluster as a native storage domain (rather than posixfs) is still in reviews (and has patches only for vdsm side).<br>
<a href="http://gerrit.ovirt.org/#/c/6856/" target="_blank">http://gerrit.ovirt.org/#/c/<u></u>6856/</a><br>
<br>
you can also use NFS in the meantime if relevant for ceph.<br>
<br>
