Abstract

The embodiment of the invention discloses a file system quota managing method, device and system, is applied to the field of computers and is used for solving the defect of low quota operation efficiency in the prior art. The method comprises, when a file system is loaded, obtaining the quota entry of every file system quota from a storage object, wherein every quota entry contains the configuration data and the statistical data of the corresponding file system quota; generating a quota tree according to the lists of all the file system quotas, the memory management object of the quota tree comprises two memory self-balancing binary search trees, wherein the first memory self-balancing binary search tree serves for management of the quota entries of user quotas of all the file system quota, and the second memory self-balancing binary search tree serves for management of the quota entries of group quotas of all the file system quotas; updating the quota entries, and storing the updated quota entry of every file system quota in the storage object. The file system quota managing method, device and system is applicable to file system quota management.

Description

technical field [0001] The invention relates to the field of computers, in particular to a file system quota management method, device and system. Background technique [0002] After the storage resources of the file system are provided to users, if they are not limited, there will be a danger of overuse. For example, some users create a large number of files and write a large amount of data, which takes up too much storage space and prevents other users from using the file system normally. [0003] The file system quota management function provides a fine-grained storage resource management method to solve these problems. Quotas allow administrators to easily limit the resources available to a single directory, to a single user, and to a single user group. Through these methods, system administrators can rationally allocate storage resources to individual resource users, avoiding the risk that some users overuse resources and make the file system unavailable.
