Capacity counting method, system and device of distributed file system and storage medium

Abstract

The invention discloses a capacity counting method, system and device of a distributed file system and a storage medium. The method includes: acquiring total capacity of a disk in the distributed filesystem when a capacity viewing request sent by a user is received; determining a redundancy rule of the distributed file system, and establishing a correspondence relationship expression between thetotal capacity of the disk and real available capacity of the distributed file system according to the redundancy rule; and substituting the total capacity of the disk into the correspondence relationship expression to obtain the real available capacity of the distributed file system. Compared with the prior art in which displayed capacity is total capacity of disks when users view capacity of distributed file systems, the method considers data redundancy, clearly and intuitively displays the real available capacity for the user, no longer causes misunderstanding which is of the user in a useprocess of the distributed file system and on the capacity, can avoid a case where the size of a to-be-stored file exceeds the real available capacity, and thus the file cannot be saved, and providesan accurate basis for allocating storage space by the user.

Description

technical field [0001] The invention relates to the field of distributed file systems, in particular to a capacity statistics method, system, device and storage medium of a distributed file system. Background technique [0002] With the rapid development of cloud computing and big data, the application range of distributed file systems is becoming wider and wider. In the prior art, when a user checks the capacity of the distributed file system, what is displayed is the raw capacity, that is, the total capacity of the disks in the distributed file system. However, in practical application scenarios, considering data security, distributed file systems usually do data redundancy when storing data. Therefore, the real available capacity of distributed file systems is not equivalent to the total capacity of disks, which is smaller than the total capacity of disks. . It can be seen that in the process of using the distributed file system, the capacity statistics method in the pr...

Problems solved by technology

It can be seen that in the process of using the distributed file system, the capacity statistics method in the prior art may cause users to misunderstand the capacity of the distributed file system, bring troubles to users, and cannot provide accurate basis for users to allocate storage space
