Plesk User Quota
In order to get quota’s within Plesk working correctly, you will not only need to download the quota package, but you will need to modify the fstab and run quota.
- Modify /etc/fstab by adding usrquota to the options for example:
/dev/sda1 / ext3 defaults,usrquota 0 0
- Remount the partiton
mount -o remount /
- Turn off quotas
quotaoff -av
