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: [email protected][email protected][email protected][email protected][email protected][email protected][email protected][email protected] FSTAB Code: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 # / was on /dev/sdd5 during installation UUID=5376739d-9145-48f8-bf8a-f583671aea20 / ext3 defaults,usrquota,grpquota 0 1 # swap was on /dev/sdd6 during installation UUID=58b50c12-fadf-41af-aea6-be2cdfe257c2 none swap sw 0 0 /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0 What have I do?
