Is it a new bug.. One needs to remember, for the new btrfs features (from yofel's ppa) e2fsprogs neet to understand the +C option (big C = nodatacow for file or folder, small c = compression).

sudo mkdir vbox
sudo chattr +C vbox

Usage: chattr [-RVf] [-+=AacDdeijsSu] [-v Version] Files...

--> Apparently the "nodatacow"-Attribute-setting is not understood by the e2fsprogs in precise :-((
