Re: Large discrepancy in reported disk usage on USR partition

I have inherited some servers running various releases of FreeBSD and I am
having some trouble with the /usr partition on one of these boxen.

The problem is that there appears to be far more space used on the USR
partition than there are actual files on the partition. The utility "df -h"
reports 25GB used (i.e. nearly the whole partition), but "du -x /usr"
reports only 7.6GB of files.

Have you tried playing with tunefs(8), -m flag?

I can't reproduce this behaviour on any of our systems.
