Unable to setup the Hard Disk quota for a domain: field is greyed-out, hard disk quota is not supported due to configuration of server file system

Note: hard disk quota setup depends on the filesystem. In the example below, the steps are performed for ext3 and xfs filesystems, while on another filesystem actions will differ.

For ext3 filesystem:

1. Connect to the server via SSH.

2. 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:

   CONFIG_TEXT: usermng: Unable to turn on user quota. User quota not supported on device '/dev/sda3'
   System error 3: No such process

   OR

   CONFIG_TEXT: 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:

   CONFIG_TEXT: /dev/hda1 / ext3 defaults,usrquota 1 1

3. Remount the partition:

   # mount -o remount /

4. Create, check and repair quota files:

   # /sbin/quotacheck -cfmvF vfsv0 /

   Note: If the command is unknown, install quota package.

5. Update the user quota with this command line:

   # quotaon /dev/hda1

6. Make sure that the aquota format is used.

   There should be an aquota.user file in the root of every partition where the quota is enabled.

   If there is the quota.user file remove it and create correct one:

   Note: change the "/dev/hda1" device in commands below to the correct one.

   # rm -f quota.user
   # touch aquota.user
   # /sbin/quotacheck -fmv /dev/hda1

7. Go to the Plesk > Tools & Settings > Server Components page and click the Refresh button to update information about quota.

   Note: A separate component will not appear, but Plesk components cache will be updated to include new information and isHardQuotaEnabled will be true in psa database:
   # plesk db "select * from ServiceNodeEnvironment where name='isHardQuotaEnabled'"
   +---------------+---------+--------------------+-------+
   | serviceNodeId | section | name | value |
   +---------------+---------+--------------------+-------+
   | 1 | os | isHardQuotaEnabled | true |
   +---------------+---------+--------------------+-------+

For xfs filesystem:

1. Connect to the server via SSH
2. Make sure the package quota is installed:

   # rpm -qa | grep quota

   If it is not, install it:

   # yum install quota -y

3. Open /etc/default/grub file using any text editor, find the line beginning with GRUB_CMDLINE_LINUX, and append the rootflags value, separated from others by a space:

   CONFIG_TEXT: GRUB_CMDLINE_LINUX="<...> <...> rootflags=usrquota,grpquota"

4. Make a backup of the GRUB config file:

   # cp /boot/grub2/grub.cfg /boot/grub2/grub.cfg.orig

5. Create a new GRUB config file:

   # grub2-mkconfig -o /boot/grub2/grub.cfg

6. Modify /etc/fstab file, adding the usrquota and grpquota mount options:

   CONFIG_TEXT: /dev/mapper/centos/srv1-root / xfs defaults,uquota,gquota 0 0

   Note: if /var is mounted on another partition better add usrquota and grpquota there too

7. Reset currently saved quota state in Plesk database:

   # plesk sbin packagemng -sdf

8. Re-log in to Plesk or go to the Tools & Settings > Server Components page and click the Refresh button to update information about quota.
9. Verify if disk quota is enabled in Plesk:

   # plesk db "select * from ServiceNodeEnvironment where name='isHardQuotaEnabled'"

   or:

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

1. Make sure that the quotaugidlimit parameter is not set to zero and that it is greater than the number of users and groups in the CT. This limit can be adjusted from the Hardware Node with the following:

   # vzctl set CTID --quotaugidlimit 500 --save
   # vzctl stop CTID
   # vzctl start CTID

   Where CTID is the ID of the Virtuozzo container with Plesk.

2. Execute the packagemng utility to recreate the backend cache in Plesk:

   # /usr/local/psa/admin/sbin/packagemng --set-dirty-flag

   OR
   Go to the Plesk > Tools & Settings > Server Components page and click the Refresh button to update information about quota.

   Note: A separate component will not appear, but Plesk components cache will be updated to include new information and isHardQuotaEnabled will be true in psa database:
   # plesk db "select * from ServiceNodeEnvironment where name='isHardQuotaEnabled'"
   +---------------+---------+--------------------+-------+
   | serviceNodeId | section | name | value |
   +---------------+---------+--------------------+-------+
   | 1 | os | isHardQuotaEnabled | true |
   +---------------+---------+--------------------+-------+
