I agree that btrfs is an interesting technology and it would be great to have 
people work on it to make it more stable and see what it can do for us in gluster.

That said, I think that XFS will continue to be the most stable and high 
performance file system for the next few years and has become increasingly 
common across many distros and in places like openstack :)  Always interesting 
to hear what you find worrying about XFS or why it does not meet your needs.
