No discrepancy on my laptop:
Code:
$ du -sdh /
  11G
$ df -h /
Filesystem            size  used  avail capacity  Mounted on
/dev/dsk/c0d0s0        13G    12G  525M    96%    /
It might be some quite big directories are unreadable for your account. If so run the du command as root.

Otherwise, very big files may be still open by some processes but have been removed from their directories.

i see. got any tips on how can i track these directories?

You can't track the directories as the files are removed.

What you need to track are the processes having big files open. Here is a command that will show the size of the 10 largest currently open files:

Code:
pfiles /proc/* | grep IFREG | grep size | sed 's/.*size://' | sort -n | tail
