problems using du (vs bdf)

[Fernando Jose P de Souz]

Hi,

I have a doubt with du. look for /x0101 (Oracle Binary)

Why there is a difference of 1 Gb when I use du?

There are three states for regions on the disk:

1) free

2) used  (includes metadata)

3) unlinked but still open

It is this third state that du doesn't know about since it walks the directory tree.
