and the error from the vdsm.log only show up on the UEK kernel. -- Chris On Wed, Aug 12, 2015 at 9:34 AM, Chris Liebman <chris.l(a)taboola.com&gt; wrote: > > Hi, > I'm new to oVirt and recently built a 10 node ovirt 3.5 DC with shared > storage using gluster configured as distributed-replicated (replication = > 2).
