Symptoms

On a Linux-based system, the root file system is filling up by some unknown process. It continues regardless of what files are moved or cleaned from the file system.

/dev/mapper/VGExaDb-LVDbSys1
             ext3     30G   29G     0 100% /

There are no large files to account for the full file system:

    # find / -xdev -type f -size +100M -exec ls -lh {} \;

There are no large directories to account for the full file system:

    # du -h --max-depth=1 /

    42M     /sbin

    13M     /etc

    2.4G    /usr

    45M    /tmp

    451M   /var

    192M   /lib

(and so on)
