du missing about 20 gigs

[rrsub]

I'm missing 20 gigs and I can't tell where it is.

Usually, I have log files that I manually delete (they're backup log files and I don't need them, I don't want automatic because I want to manually snoop around in other areas as I delete them weekly)

So anyway, here's my evidence:

# df -h
Filesystem            Size  Used Avail Use% Mounted on
...
/dev/hda7              27G   20G  6.6G  75% /home
...
(so you see that /home has it's own partition

# df -h /home
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda7              27G   20G  6.6G  75% /home

-Then the whammy-

# du -hs /home
2.9G    /home

and each subdirectory adds up to the 2.9G value.

Found where it was.

I had a 17G log file that I deleted a week ago that memory hadn't let go of.

lsof +L1

showed me the open file and the (deleted) status

I killed the process (which is a Java process) and got the space back.
