disk-fill: dd fill 'no space left on device' should be successful

[sunny-xiao]

when i use the command 'chaosd attack disk fill -p /home -s 30G -f=false' to fill my disk, it does works, but the experiment failed and i cannot get the uid to recover it,only i can do is finding the example file and delete it manually. I think in this case, the experiment should be successful and i can recover it.
