I do believe something went wrong after fully updating everything last Friday.  I updated all the ovirt compute nodes on Friday and gluster/engine on Saturday.  I have been experiencing these issues every since.  I have pour over engine.log and seems to be connection to storage issue.

Subject: Re: [ovirt-users] Ovirt Cluster completely unstable
 
I have a three node HCI gluster which was previously running 4.2 with zero problems.  I just upgraded it yesterday.  I ran in to a few bugs right away with the upgrade process, but aside from that I also discovered other users with severe GlusterFS problems since the upgrade to new GlusterFS version.  It is less than 24 hours since I upgrade my cluster and I just got a notice that one of my GlusterFS bricks is offline.  There does appear to be a very real and serious issue here with the latest updates.

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.
