What's eating my disk space
Hello,

I've got a server I inherited that is continually losing disk space. I've tried looking for large files, but am unable to find any offenders - please point me to any resources that may help as well.


Thanks

Thanks for your reply, I'm gonna look into it.

Also, I was able to find a large file before I posted that I deleted but it didn't release the file space it occupied - a reboot reallocated the disk space.

The file may have been open (was it a log file?) so space would not have been released by an rm - a cat /dev/null > filename (or just > filename) will make the file zero size, even it if it being actively used.

Use this:
du -h --max-depth=1 on /
It will tell you exactly which directory is the culprit..Then you use it down the tree, and you find out where is the big file(s) located...
du -h --max-depth=1 /var/log/apache2 (for example)..
Hope it helps.
