Abstract

The invention discloses a method for user file quota, which is applied to a data server and comprises the following steps: when receiving a new file creating request sent by a client, determining userinformation of the new file creating request and the number of new files; Judging whether the number of the files exceeds the quota in the new file creating process or not by utilizing the residual file number and the number of the new files in the file quota information corresponding to the user information; If yes, forbidding the client to create a new file; If not, allowing the client to create a new file, and updating the residual file amount in the file quota information; According to the method, the data server communicates with the client to realize user file quota management, so thatthe problem that the performance of the whole distributed file system is influenced by too many IO request times caused by interaction of the data server, the client and the user file quota can be avoided; The invention also discloses a user file quota device, a distributed file system and a computer readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of distributed files, in particular to a method and device for user file quotas, a distributed file system and a computer-readable storage medium. Background technique [0002] With the development of information technology, the processing and recording of various data has produced massive data. Faced with the storage and processing of massive data, it is currently solved through cloud computing. In the storage system of cloud computing, distributed storage devices are connected into a virtual whole through the network and distributed file system to form an efficient, safe and reliable storage system. In the distributed architecture, it is mainly composed of data server, metadata server and client. Among them, the data server is mainly responsible for data storage; the metadata server is mainly responsible for the management of metadata; the client is mainly responsible for providing interactive interfaces...
