Hello!

Acording to http://www.ovirt.org/Node_Glusterfs_Support glusterfs on 
ovirt node should be supported. But I have some difficulties to 
implement it.


I installed ovirt (nested kvm - home testing) following "Up and Running 
with oVirt 3.3) using Fedora19
Install went well. Everything is working fine.

Now I created two hosts (nested kvm - ovirt node fc19 - just for 
testing) and added them in oVirt.
Super fine - working!

Now I'd like to use this hosts as glustefs nodes too. Acording to google 
(I'm googling for two days now) I'ts possible, but I can not find any 
usable how-to

1. I removed these two hosts from default data center
2. I created new data center (type: GlusterFS)
3. I created new cluster (Enable Gluster Service checked)
4. I added host
5. Now I get error message in events: "Could not find gluster uuid of 
server host1 on Cluster Cluster1."


If I ssh to my host (fc19 node) glusterd.service is not running. If I 
try to run it It returns error

here is the log:

Acording to log /var/lib/glusterd/glusterd.info is missing and can not 
be created because fs is mounted "ro".


Now I'm stuck!
What am I missing?


tnx for help!
