There is something strange on my root drive. Namely, df shows most
of this partition used up but du shows very little usage. 

        [root@jhammer6 /]# df -h
        Filesystem            Size  Used Avail Use% Mounted on
        /dev/hda1             3.7G  3.0G  487M  86% /
        /dev/hda4              22G   15G  5.9G  72% /mnt/hda4
        /dev/hda3             1.4G  1.1G  216M  84% /mnt/hda3
        /dev/hdb1              27G   13G   13G  50% /mnt/hdb1
        /dev/hdc1              71G   17G   50G  25% /mnt/hdc1

Note that /dev/hda1, / , has 3 gigs of data it. Now, I have moved almost
everything off root, including home, usr, opt, and bin and made symbolic
links to them. 
I wrote a script which runs du -csh against each directory
in / except for the mounted partitions.
Here is the script:

        #!/bin/bash
        cd /
        for i in `dir -1`
        do
                [  "$i" = mnt ]  ||  {
                du -csh $i  | sed '/total/d'
                }
        done

Here is the output of the above script:

        428k    System.map
        428k    System.old
        2.0k    auto
        5.9M    bin
        3.3M    boot
        15k     dev
        3.4M    etc
        0       home
        1.0k    initrd
        11k     install
        1.0k    junk
        41M     lib
        12k     lost+found
        0       opt
        0       proc
        20M     root
        6.5M    sbin
        208k    shlib
        0       tftpboot
        1.9M    tmp
        0       usr
        0       var
        882k    vmlinuz
        626k    vmlinuz-NoModules

Now, I don't see any directories here even remotely approaching a gig.  I
just ran fsck on /dev/hda1, and no errors were reported. So,
my question is, what am I missing?
Thanks,
Joel
