Here's some of the great blogs from the RDO community which you may have missed in recent weeks:
Using NFS for OpenStack (glance,nova) with selinux by Fabian Arrotin
As announced already, I was (between other things) playing with Openstack/RDO and had deployed some small openstack setup in the CentOS Infra. Then I had to look at our existing DevCloud setup. This setup was based on Opennebula running on CentOS 6, and also using Gluster as backend for the VM store. That's when I found out that Gluster isn't a valid option anymore : Gluster is was deprecated and was now even removed from Cinder. Sad as one advantage of gluster is that you could (you had to ! ) user libgfapi so that qemu-kvm process could talk directly to gluster through ligbfapi and not accessing VM images over locally mounted gluster volumes (please, don't even try to do that, through fuse).
Nested quota models by Tim Bell

Understanding ceph-ansible in TripleO by Giulio Fidente
One of the goals for the TripleO Pike release was to introduce ceph-ansible as an alternative to puppet-ceph for the deployment of Ceph.
