<div>hi,</div>
<div> </div>
<div>It's really not a single point of failure ? In this way i see 2 point of failure, if the hosted-engine break and if the mount server adress break. And it's not possible to migrate the engine.</div>
<div> </div>
<p>Can you explain me why is not a point of failure for you ?</p>

<p>Hi,</p>
<p>I have 3 nodes with glusterfs installed. I configured replica 3 on my engine volume.</p>

<div>Hi,</div>
<div>on oVirt 3.6 we still not support hyper convergence that means that you cannot use the same hosts for virtualization and for storage with gluster.</div>
<div> </div>
<div>So the correct approach is renaming your hosts to:</div>
<div>host 1 : "192.168.100.101 gluster1.localdomain gluster1"<br />host 2 : "192.168.100.102 gluster2.localdomain gluster2"<br />host 3 : "192.168.100.103 gluster3.localdomain gluster3"</div>
<div> </div>
<div>On an additional host, deploy hosted-engine choosing the gluster host you prefer as your entry point: it will not be a single point of failure.</div>
<div>You don't really need to use CTDB to deploy oVirt hosted-engine.</div>
<div> </div>

<div>
<p><br />i don't want to use ctdb for my hosted-engine, but when i start hosted-engine --deploy, use localhost:/engine or gluster.localdomain:/engine, gluster.localdomain is configured in all servers /etc/hosts like :<br />host 1 : "192.168.100.101 gluster.localdomain gluster"<br />host 2 : "192.168.100.102 gluster.localdomain gluster"<br />host 3 : "192.168.100.103 gluster.localdomain gluster",</p>
<p>the setup failed with :</p>

<p>I have to use obligatory ctdb or keepalived, or existing another way ?</p>
