A few days ago i noticed the used disk space is growing... my 100Gb HD has 45% used one month ago, now its on 92%... ive deleted log files, every site delete its own old log files.. i cant understand why its growing 200/300Mb per day. Where do you think i must check for growing files? Spool folder?
i would run a nightly df -h / | grep M an compare that from two days so you should see where to take a look.
Look at this, its the Space stats from one site: Assigned space: 2000 MB used: 71305.39k /backup 136M /user 13M /cgi-bin 4,0K /phptmp 4,0K /web 310M /log 964M /ssl 4,0K DB::MySQL 71304.4k The account is not right, it should be: Used: 1494Mb and its 71Mb. A little difference. Plus, for future releases take a look to fix the webalizer script, as you see there are 964Mb in the las log file, my webalizer script runs every 6 hours, so it would be a 4Gb daily log. Im thinking about run it hourly.
You muste enable the du command to be executed with sudo. Have a look here: http://www.howtoforge.com/forums/showthread.php?t=2064
