Linux quota overview-general Linux technology-Linux technology and application information. For more information, see the following section. The limit on disk usage is the so-called Disk quota (quota)
In Linux, the disk quota is divided into user quota and group quota. The Group quota is a comprehensive limitation on all users in a group.
The disk quota is generally based on the disk size occupied by a user and the number of all files.
In Linux, the disk quota is divided into soft limits (which can be exceeded) and Hard Limits (which cannot be exceeded) based on whether the disk quota can be exceeded. However, after the soft limit is exceeded, it automatically becomes hard.
In Linux, the disk quota varies according to the restricted items, which can be divided into the space limit (blocks size) and the number of files limit (inodes number ).
Soft limit: The maximum disk space and maximum number of files that a user can have in the file system. This limit can be temporarily exceeded within a certain grace period.
Hard limit: the absolute number of disk space or files that a user can possess cannot exceed this limit.
