[ovirt-users] Ovirt Cluster completely unstable

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.
