Problems solved by technology

Since the client is separated from the metadata service, there is a lag in the amount of usage from the metadata update to each client, so when the capacity quota function is used in multi-clients, the excess will occur, and the more directory levels the more the excess serious
In the current distributed file system, there is no precise quota implementation scheme

Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] The embodiment of the present invention discloses a distributed file system directory quota method, see figure 1 As shown, the method includes:

[0042] S11: Receive a service processing instruction.

[0043] Specifically, the business processing instruction includes the quota required for this business and the tasks to be performed. Therefore, the business processing instruction is used to determine whether a quota is required in the future. The busin...

Abstract

The invention discloses a distributed file system directory quota method, system and device and a computer readable storage medium. The method comprises the steps of receiving a service processing instruction; judging whether the quota margin of a local directory meets the margin requirement for processing the service corresponding to the service processing instruction or not; if not, sending thequota application information to a metadata server; if yes, processing the service, and judging whether the accumulated quota usage amount of the local directory meets a preset reporting condition ornot during the last period for reporting of the quota margin of the local directory; if so, reporting the current quota margin of the local directory to the metadata server. According to the present invention, whether the quota margin of the local directory can meet the service processing requirement or not is actively judged before the service is processed, if not, the quota is applied to the metadata server, so that it is ensured that the situation that the quota is excessive after the service is processed is avoided, meanwhile, reporting is conducted only when the preset reporting conditionis met, the broadcasting frequency is reduced, and the broadcasting efficiency is improved.

Description

technical field [0001] The invention relates to the field of distributed storage, in particular to a distributed file system directory quota method, system, device and computer-readable storage medium. Background technique [0002] In a distributed file system, the implementation of directory capacity quotas is relatively simple and depends on the usage in directory metadata. Since the client is separated from the metadata service, there is a lag in the usage from the metadata update to each client, so when the capacity quota function is used in multi-clients, the excess will occur, and the more directory levels the more the excess serious. In the current distributed file system, there is no precise quota implementation scheme. [0003] Therefore, a distributed file system directory quota method is needed to avoid the situation of excess. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a distributed file system dire...
