df not reporting correct disk usage

July 27th, 2011 No comments

I had a problem where df and du disagreed with the amount of disk usage. The cause was processes holding on to unlinked files. Running the following identified the processes:

ls -ld /proc/*/fd/* 2>&1 | fgrep ‘(deleted)’

I killed the processes and df is now showing the correct information.
