have two nodes running the hosted engine and gluster setup
for replicate between them. Mounting to localhost seems to
be working so far. I have live migrated the engine, pulled
the plug on a running node, and rebooted each node to ensure
it all works properly. I have had few issues with this
setup. I didn’t like ctdb because it adds another layer of
complexity that is unnecessary for MY setup.<o:p></o:p></span></p>

not do this, and just create a gluster volume on all the

<p class="MsoNormal" style="margin-bottom:12.0pt"><br>
Theoretically, it should work - if you make sure that you have
a replica 3 gluster volume spread across 3 nodes, and these 3
nodes are your compute nodes as well - you should be fine
without CTDB setup for failover and mounting as localhost.<br>
<br>
But I've not tried this to recommend it. Maybe if others have
tried it, they can chime in?<br>
<br>
Btw, is there any reason you do not want to set up CTDB?<br>
