I have setup an environment with 8 glustefs nodes in
distributed+replicated mode. Instead of CTDB, I'm using keepalived. It
works pretty well.

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 VMs and
what not do not run in this fashion.
Hope This helps

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.

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,
