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 bugs. > root@roura:~# btrfs filesystem show --all-devices > Label: none uuid: 12880174-8337-47bc-be05-f485a0b7503f > Total devices 1 FS bytes used 72.67GB > devid 1 size 130.00GB used 130.00GB path /dev/sdd 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. Hugo.
