Thanks Jason. I am running a development cluster (using vstart), so all the running OSDs are running the code from Dec 6th(master branch). Could you please point me in the direction of how to run it on librbd-backed clients ?

The kernel krbd driver doesn't support the new RBD data pool feature. This will only function using librbd-backed clients. The error that you are seeing with "rbd feature disable" is unexpected -- any chance your OSDs are old and don't support the feature?
