Doug, One of the biggest requirements to use cephBroker today is the authentication "cephx" introduced by default on recent Ceph versions.
My plan is to use Ubuntu or a recent Fedora, but not CentOS because is pretty outdated. What are your toughts on QFS? The main reason for me to use a DFS will be hypertable which I am keen to hear about the future directions on this subject. I have building & deploying experience with Opscode Chef and also slowly I am creating a hypertable cookbook for a few use cases. How do you think I can help Hypertable?
