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>

<div>Also, how can I upgrade the nodes? Need i'm to a "yum

<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>
<br>
