Hi everyone,
Until today my environment was fully updated (3.6.5+centos7.2) with 3 nodes
(kvm1,kvm2 and kvm3 hosts) . I also have 3 external gluster nodes
(gluster-root1,gluster1 and gluster2 hosts ) , replica 3, which the engine
storage domain is sitting on top (3.7.11 fully updated+centos7.2)
For some weird reason i've been receiving emails from oVirt with
EngineUnexpectedDown (attached picture) on a daily basis more or less, but
the engine seems to be working fine and my vm's are up and running
normally. I've never had any issue to access the User Interface to manage
the vm's
Today I run "yum update" on the nodes and realised that vdsm was outdated,
so I updated the kvm hosts and they are now , again, fully updated.
Reviewing the logs It seems to be an intermittent connectivity issue when
trying to access the gluster engine storage domain as you can see below. I
don't have any network issue in place and I'm 100% sure about it. I have
another oVirt Cluster using the same network and using a engine storage
domain on top of an iSCSI Storage Array with no issues.
*Here seems to be the issue:*

*Question: Anyone know what might be happening? I have several gluster
config's, as you can see below. All the storage domain are using the same
config's*
*More information:*
I have the "engine" storage domain, "vmos1" storage domain and
"master"
storage domain, so everything looks good.
