I run Replica 3 VM hosting (gfapi) via a 3 node proxmox cluster. Have 
done a lot of rolling node updates, power failures etc, never had a 
problem. Performance is better than any other DFS I've tried (Ceph, 
lizard/moose). Never did get DRDB working.


nb: ZFS Bricks, with each brick RAID10 - so a little paranoid on the 
redundancy :)


For me, glusters biggest problem is its lack of flexibility in adding 
bricks and nodes.And replacing them is an exercise in nail biting.  
Hoping V4 improves on this though maybe that will lead to performance 
trade offs.
