Try running 
/# du -c -h --max-depth=1 /*

The -c will give a grand total.  Without it, its telling you that you
have 9.7G in the root directory itself.  Also, use df -h.  -H is --si.
With one, multiples of a thousand are 1000, with the other they are
1024.  You may as well compare apples XOR oranges.
