We strongly recommend using the latest available kernel (currently
3.5 or 3.6-rc4) if you're running btrfs. The code is still moving very
quickly, and the main devs are still finding and fixing fairly serious

You may want to read about df[1], and then about ENOSPC errors[2].
If you've still got questions after that, please do come back and
ask them.
