Abstract:
1. A system for controlling directory capacities with an accuracy tolerant ratio, comprising: a shared disk for storage of files and directories, information on each directory comprising a limit capacity, a report capacity, an allocated capacity and an occupied capacity, the directories being divided into controlled directories and uncontrolled directories; and a directory management module for: determining whether a remaining capacity of a directory is greater than or equal to an applied capacity, and updating an occupied capacity of the directory if the remaining capacity of the directory is greater than or equal to the applied capacity; checking whether an occupied capacity is greater than an accuracy tolerance of a difference between a report capacity and a corresponding allocated capacity, and updating directory information of the directory if the occupied capacity is less than the accuracy tolerance of the difference between the report capacity and the allocated capacity, and updating the report capacity of the directory if the occupied capacity is greater than the accuracy tolerance of the difference between the report capacity and the allocated capacity.
