[Q] Where does all the space go?

I created a filesystem as follows:

mke2fs -j -O dir_index -O sparse_super -T largefile /dev/drbd/6

Here's the the output from df

Filesystem            Size  Used Avail Use%
/dev/drbd/6           475G   33M  452G   1%

It seems that ext3 has taken 23 GB, which is about 5% of the total 
disk size, for itself. Is that right?

If that is, indeed, the case, why does df just list 33M as being used?
