<= p =3D class=3D3DMsoNormal>I have two nodes running the hosted engine and gluster setup for =3D replicate between them. Mounting to localhost seems to be working so =3D far. I have live migrated the engine, pulled the plug on a running node, = =3D and rebooted each node to ensure it all works properly. I have had few =3D issues with this setup. I didn’t like ctdb because it adds another = =3D layer of complexity that is unnecessary for MY =3D setup.

Node1 gluster drive on sdb

Node2 gluster drive on sdb

Both replicate and are the same make and model drive. =3D

ovirt-ha running on both for hosted-engine

This setup is for hosted engine only, my actual storage for =3D VM’s and what not do not run in this fashion. =3D

Hope This helps

Nope in fact I followed the guide and =3D found CTDB works quite well. I am just trying to figure out the =3D benefit because that would be another component to consider in the =3D architecture.

I was planning on making a Gluster Data domain to = =3D test, and found some great information on this page: = =3D http://community.redhat.com/blog/2014/05/ovirt-3-4-glusterized/
The article the author uses the CTDB service for VIP =3D failover. Is it possible/recommended to not do this, and just =3D create a gluster volume on all the hosts in a cluster, then create the =3D Gluster data domain as =3D localhost:<gluster_vol>?

Theoretically, it = =3D should work - if you make sure that you have a replica 3 gluster volume =3D spread across 3 nodes, and these 3 nodes are your compute nodes as well =3D - you should be fine without CTDB setup for failover and mounting as =3D localhost.

But I've not tried this to recommend it. Maybe if =3D others have tried it, they can chime in?

Btw, is there any reason = =3D you do not want to set up CTDB?

Thanks,

Ryan
