Allowed Disk Space value in a service plan becomes Unlimited, when "Notify when disk space usage reaches" option is set via CLI

Symptoms

• Disk Space limit in a service plan is not Unlimited :
  
• Changing Notify when disk space usage reaches value via CLI changes Disk Space limit to Unlimited:
  

  # plesk bin service_plan -u "Service Plan" -disk_space_soft 1G

  

Cause

This is Plesk bug with ID #PPPM-7636 and will be fixed in future Plesk updates.

Resolution

Apply the following workaround:

1. Connect to the server using SSH
2. Explicitly specify Disk Space value in CLI command when changing disk_space_soft parameter (that stands for Notify when disk space usage reaches) , for example:

   # plesk bin service_plan -u "service_plan_name" -disk_space_soft 1G -disk_space 10G
