Guess I found another bug - three disks with >>3tb free space, but df
still shows 0 available bytes. Sure I can probably work around it somehow,
but no, I refuse to accept that this is supposedly a user problem - surely
btrfs could create more raid1 metadata with _three disks with lots of free
space_.
