This is a multipart message in MIME format. ------=_NextPart_000_002C_01D0406B.C7D667E0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit I 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. Node1 gluster drive on sdb Node2 gluster drive on sdb Both replicate and are the same make and model drive. ovirt-ha running on both for hosted-engine This setup is for hosted engine only, my actual storage for VM's and what not do not run in this fashion. Hope This helps Donny D From: users-bounces@ovirt.org [mailto:users-bounces@ovirt.org] On Behalf Of Groten, Ryan Sent: Wednesday, February 4, 2015 10:11 AM To: Sahina Bose; users@ovirt.org Subject: Re: [ovirt-users] Help understanding Gluster in oVirt Nope in fact I followed the guide and found CTDB works quite well. I am just trying to figure out the benefit because that would be another component to consider in the architecture.

Is it possible/recommended to not do this, and just create a gluster volume on all the hosts in a cluster, then create the Gluster data domain as localhost:<gluster_vol>? 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. But I've not tried this to recommend it. Maybe if others have tried it, they can chime in? Btw, is there any reason you do not want to set up CTDB?
