Hey,
do you know if the data in /var/lib/glusterd needs to survive reboots?
If not, then this patch http://gerrit.ovirt.org/20540 will probably fix
I'll ack this once you fix the typo in the summary (s/bar/var/)

the problem. The patch just adds that path to /etc/rwtab.d/ovirt - this
will tell the read-only root to make that path writable at boot.
Due to the nature of Node you will need to build your own image or wait
until the patch lands in an image. Editing the rwtab file by hand at
runtime won't have an effect.

Progress report:
I remounted fs on oVirt nodes rw, started glusterd with no errors.
Then I activated hosts in oVirt Engine. Also no errors! Yei!
Yey! :)
Yes, mount -oremount,rw make's the FS temporarily writeable. But you
will have issues as soon as you reboot.
We'll need to investigate which paths need to be persisted (so the data
written to them survives a reboot) and which only need to be write-able
e.g. for temporary data.
Would you mind opening a bug for this?

Then I created volume (replication), added two bricks (oVirt nodes),
and started volume. Seems fine. I checkd on node1:
# gluster volume info
Volume Name: data_vol
Type: Replicate
Volume ID: a1cdc762-2198-47e2-9b4a-58fd0571b269
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: 192.168.254.124:/data/gluster
Brick2: 192.168.254.141:/data/gluster
Options Reconfigured:
storage.owner-gid: 36
storage.owner-uid: 36
auth.allow: *
user.cifs: on
nfs.disable: off
WORKING!
BUT... Now i can not create storage domain. When I hit OK button on
"New storage domain dialog", process is running very long. Eventually
this process stops and returns " Error while executing action Add
Storage Connection: Network error during communication with the
Host".
I'm stuck again :-( in need for HELP!
Could you please provide the logfiles mentioned here:

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:

What am I missing?
