In my case I am continuing with oVirt node 4.3.8 based gluster 6.7 for the time being. I have resolved the issue by manually copying all disk images to a new gluster volume which took days specially since disks on gluster still don't support sparse file copy. But the threat of a temporary network failure bringing down the complete oVirt setup is a bit too much risk.

Hey,

I do not have the faulty cluster anymore; It's a production environment
with HA requirements so I really cant take it down for days or even
worse, weeks.

I am now running of CentOS7 (manual install) with manual Gluster 7.0
installation and current ovirt. So far so good.

Time will tell :)
