Hi Alastair,<br>
<br>
This could be a mismatch in the hostname identified in ovirt and
gluster.<br>
<br>
You could check for any exceptions from GlusterSyncJob in
engine.log.<br>
<br>
Also, what version of ovirt are you using. And the compatibility
version of your cluster?<br>

This can mostly happen due to following reasons<br>
- "gluster volume status vm-store" is not consistently
returning the right output<br>
- ovirt-engine is not able to identify the bricks properly<br>
<br>
Anyway, engine.log will give better clarity.
