Well, that is what I alluded to in my commentary.

What I was trying to find out was if the decision was based on a 
technical aspect in the technologies involved (such as Gluster scaling) 
or simply the reality of open source project politics (i.e. cat 
herding/familiarity).

It appears to be the latter.

That is fine. The OpenStack project/community is already somewhat <ahem> 
"unusual" enough without having to swim upstream against an incumbent 
technology.

We ($dayjob) have played with most of the distributed FS/Disk systems 
and use at least 3 different ones at the present. Gluster has it role in 
our system (mostly VMs in host clusters).

I've always been curious as to what the RedHat position on the Gluster 
use case vs Ceph use case was in case we were missing an opportunity.
