It's nice to hear success stories for once.  I would suggest being 
careful of using BTRFS raid5 or raid6 in production, there are probably 
still bugs that haven't yet been discovered.  Secondarily, if you can 
deal with slightly more setup and maintenance overhead, BTRFS works 
_very_ well on top of LVM (it makes online data migration much easier, 
and provides easy ways to do layered RAID setups).
