Hey,

I couldn't make the meeting, but I am interested in BTRFS. I added
this in puppet-gluster a bunch of months ago as a feature branch.

https://bugzilla.redhat.com/show_bug.cgi?id=1094860

I just pushed it to git master.

https://github.com/purpleidea/puppet-gluster/commit/6c962083d8b100dcaeb6f11dbe61e6071f3d13f0

The reason I want btrfs support, is I want glusterfs to eventually be
able to support reflinks across gluster volumes. There is a strong use
case for this feature.

Let me know if this helps!
Cheers,
James
