		Hello.
	I previously reported results of BTRFS synthetical tests. Now I have
tried it under a real-life usage.
/dev/sda6              29G   18G   12G  61% /nix/store
/dev/sda6             30009388  18103372  11906016  61% /nix/store

I can create small files, but trying to write a big file gives
dd: writing `/nix/store/garbage1': No space left on device

btrfs-show shows the following:
Label: store  uuid: 8eac2c04-5e1c-4f47-b4eb-b56bea578cb1
        Total devices 1 FS bytes used 17.26GB
        devid    1 size 28.62GB used 28.62GB path /dev/sda6

Why does such a signinficant misreporting occur?
