[ovirt-users] Help understanding Gluster in oVirt

[Groten, Ryan]

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.

I was planning on making a Gluster Data domain to test, and found some great information on this page: http://community.redhat.com/blog/2014/05/ovirt-3-4-glusterized/
The article the author uses the CTDB service for VIP failover.  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?



Thanks,
