Ok, I was thinking it's mounted twice because "df" show me the same 
space usage.
% df -H  |grep -E '/$'
rootfs                                                    14G   13G  
2,0G  87% /
/dev/disk/by-uuid/xxxxxxww                 14G   13G  2,0G  87% /

As It's my misinterpretation, you can close the bug.
