Make sure that the quota is supported by the kernel. It should be compiled into the kernel or loaded as a module.

To check if the quota is configured properly use this command:

# /usr/local/psa/admin/sbin/usermng --isquotable

Normally, it should return the "0" value.

If the utility returns the following error message:

usermng: Unable to turn on user quota. User quota not supported on device '/dev/sda1'
System error 3: No such process

OR

usermng: Userquota is not enabled on device: /dev/mapper/centos-root

then enable quota in the /etc/fstab file for the partitions on which Plesk stores data on, e.g. as follows:

/dev/hda1 / ext4 defaults,usrquota 1 1
Remount the partition:

# mount -o remount /
Enable quota (use actual partition name, /dev/sda1 is an example):

# sudo tune2fs -O quota /dev/sda1
Create, check and…
