Hi,
I would have a look at engine.log, it might provide usefull informations.
Also, i would test i different storage type (maybe a quick nfs data domain ) and see if problem persist with that one too.

I'm abandoning my production ovirt cluster due to instability.   I have a 7 host cluster running about 300 vms and have been for over a year.  It has become unstable over the past three days.  I have random hosts both, compute and storage disconnecting.  AND many vms disconnecting and becoming unusable.

7 host are 4 compute hosts running Ovirt 4.2.8 and three glusterfs hosts running 3.12.5.  I submitted a bugzilla bug and they immediately assigned it to the storage people but have not responded with any meaningful information.  I have submitted several logs. 

I have found some discussion on problems with instability with gluster 3.12.5.  I would be willing to upgrade my gluster to a more stable version if that's the culprit.  I installed gluster using the ovirt gui and this is the version the ovirt gui installed.

Is there an ovirt health monitor available?  Where should I be looking to get a resolution the problems I'm facing.
