What are Disk Quotas?

In the current version of Parallels Cloud Server, system administrators can limit the amount of disk space Containers can use. Such quotas are known as per-Container or first-level quotas. In addition, administrators can enable or disable per-user and per-group quotas that are known as second-level quotas and allow you to limit disk space that individual users and groups in a Container can use.

By default, first-level quotas on your Hardware Node are enabled (as defined in the /etc/vz/vz.conf configuration file), whereas second-level quotas must be turned on for each Container separately (in the corresponding Container configuration files). It is impossible to turn on second-level disk quotas for a Container if first-level disk quotas are off.
