disk usage

[Benjamin Griese]

That could help you if there are open files which are not deleted.
I had that sometimes in the past, where a ugly-written script for logration
moved away some logfiles and created a new one at the same place with the
old name.
In this case the old file was in use by the process which writes to this
process while moving and the filesystem for the logfile slowly grew up for
no appearent reason.

Good luck! :)

*Listing 5. Using lsof on Linux to look for a deleted file*

# lsof | grep error_log
httpd      2452     root    2w      REG       33,2      499    3090660
					/var/log/httpd/error_log (deleted)
httpd      2452     root    7w      REG       33,2      499    3090660
					/var/log/httpd/error_log (deleted)
