Hi,

To find files larger than, say, 100000 bytes in the root filesystem, try

find / -xdev -type f -size +100000c | xargs ls -l

The ls command will show you the date the files were last modified.

A quick place to look is in the /dev directory. It's not unusual to see a situation where an application attempts to write to a non-existant device but instead starts filling up a file.

Hi,
To find out which directory is eating up the most space, you can start a search from root using:

cd /
du -s * |sort -nk1

The last line will be the directory/file eating up the biggest space of your hardisk.

cd to that particular directory and repeat the du -s * command

Hi,

You also need to be careful of open files which are "invisible" to du but "visible" to bdf. In this case, your du and bdf results will not tally ie. du will report a smaller usage than bdf.

To identify open files, you can perform an lsof on /. If the open file listed does not exist as a physical file, terminate the process that is holding on to the open file.

This happens especially to logging processes whereby the log file grew too large and was deleted without restarting the process properly, resulting in the process still holding on to the opened log file.

Hope this helps. Regards.
