Well I think there is a btrfs superblock still present from the full-disk filesystem. Due to the offset of the first partition from the start of the disk, this superblock was not overwritten when you created the filesystem inside the partition. But they very much overlap and the full-disk superblock will probably eventually be overwritten by elements from the partition filesystem. How you would go about erasing the stale superblock and whether it is safe to do so I can't say though.
Ok, that explains it, and it is no problem for me. I was just confused by the output and thought that this may be related to the "no space" problem. I just installed kernel 3.3.3, and the problem with "no space" seems to be gone. Thanks for your quick help.
