[NTLUG:Discuss] disk space mystery

[Kevin Brannen]

For all you sleuths out there, here's one for you that's puzzling me...

When I do a "df /"  I get:

            1024-blocks   Used      Available
/dev/hda6   893363        829768    17010          /

and I'm thinking, "where did it all go?", so I do:

tar -clf - / | wc -c        and get ~62M
du -Sx                      and get 59810
du -s /*  (and sum the non-mount points) and get ~60M
fsck -n /dev/hda6           and get 860417 blocks used
                                     58201 inodes
				      5135 reg. files
				      2554 dirs
        			     ~3000 other file types

Umm, which is it?  About 60M or 830M?  Why the descrepency?   Nope,
nothing in lost+found.  usr, var, home, opt are all on other
partitions.  /tmp isn't that big.  Yes, I'm doing this all as root, so
no "permission denied" messages because I can't look into various
places.

What am I overlooking?
