Hi Falko and Till, I have found a problem within this article about the Quota setup: Installing A Multiserver Setup With Dedicated Web, Email, DNS And MySQL Database Servers On Debian 5.0 With ISPConfig 3 Code: To enable quota, run these commands: touch /quota.user /quota.group chmod 600 /quota.* mount -o remount / quotacheck -avugm quotaon -avug This is the result in my box: Code: root@webserver:/# touch /quota.user /quota.group root@webserver:/# chmod 600 /quota.* root@webserver:/# mount -o remount / root@webserver:/# root@webserver:/# quotacheck -avugm quotacheck: Your kernel probably supports journaled quota but you are not using it. Consider switching to journaled quota to avoid running quotacheck after an unclean shutdown. quotacheck: WARNING - Quotafile //quota.user was probably truncated. Cannot save quota settings... quotacheck: WARNING - Quotafile //quota.group was probably truncated.
