Is this hosted-engine setup? Have you looked at

If you're upgrading from oVirt 3.5 to 3.5.1 - there's no new
dependency on glusterfs. So, you could decide not to upgrade
glusterfs and just upgrade the vdsm on the nodes.<br>

This is a productive environment, so I'm affraid so much of
upgrading...:(.I don't want glusterfs mistakes, split-brains,
etc..)</div>
<div><br>
</div>
<div>Also, I could make little downtime for upgrading, but I'm
need to know what is the trustable upgrade procedure. Is there
an official upgrade documentation for ovirt, that is contain
the glusterfs upgrde methods?</div>

<br>
There are separate documentations - for oVirt upgrade and glusterfs
upgrade. No mechanism to upgrade glusterfs on nodes from within
oVirt.<br>

If you only want to upgrade the engine to oVirt 3.5.1 - you
don't need to upgrade the gluster nodes. I understand that
your gluster nodes are separate from the virt nodes. That is,
you do not have any cluster enabled with both virt + gluster
service.<br>
<br>
glusterfs 3.6 is not necessary to upgrade engine to oVirt
3.5.1. It would only be required if you were upgrading the
cluster level (the compatibility version) which in turn would
require newer vdsm versions and gluster versions. But in your
case, I think you already have your cluster running with
glusterfs 3.5.2. What is the cluster compatibility version?<br>

<br>
By upgrade the nodes - you mean only the compute nodes? yum
upgrade on each node should work.<br>
You can also move the Host to maintenance mode and click on
Reinstall or upgrade from engine.<br>

<br>
Do you have a replica 3 volume setup across these 3
nodes?<br>
<br>
Glusterfs supports rolling upgrade for replica
volumes. <br>
But there are some issues to upgrade from 3.5 to 3.6
versions (depending on version used)<br>
Adding gluster-users & Pranith for recommended
procedures.<br>
<br>
