bdf and du discrepancy

[Ian Killer_1]

Hi gurus...

I have this situation similar to before...
http://forums.itrc.hp.com/cm/QuestionAnswer/0,,0x91c63a7b3682d611abdb0090277a778c,00.html

This time bdf reports 125 mb and du reports 60mb, but there are no stale nfs mounts.

Here are the reports...
# bdf /

Spares files?

or search on +bdf +du, it's an age-old question (with no perfect answer, I'm afraid).

You can try with lsof to find out the sparse file.

I've never used lsof before. I have it compiled and working on this box though. What are the useful parameters the use and what should I look for in the output?

Here's my lsof / output.
