5 Working With Disk Quotas

You can set disk quotas to restrict the amount of disk space or blocks that users or groups can use, to limit the number of files or inodes that users or groups can create, and to notify you when usage is reaching a specified limit. A hard limit specifies the maximum number of blocks or inodes that are available to a user or group on the file system. Users or groups can exceed a soft limit for a period, which is known as a grace period.
