<div>I have an ovirt 3.5.0 cluster with three nodes and we using
glusterfs for serving backend storage for VM-s. Glusterfs are
on same servers with ovirt.</div>
<div>We have Gluster 3.5.1 on all of nodes.</div>

<div>How can I upgrade to ovirt 3.5.1 with new glusterfs? I

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>
