Problems solved by technology

When multiple data servers and multiple clients send access requests to the same metadata server at the same time, the mutex in the metadata server will queue all requests to ensure the consistency of file data, that is, only one access at a time The request has access rights such that concurrent access to the metadata is not possible

Abstract

The invention provides a metadata server, a metadata concurrent access system and a metadata concurrent access method. The metadata server comprises an interaction unit, an access request control unit and a data read-write unit, wherein the interaction unit is used for receiving at least two access requests transmitted by a peripheral first metadata request terminal; the access request control unit is used for analyzing the at least two access requests received by the interaction unit, and if the at least two access requests include at least two read requests, allocating access authority to the at least two read request; and the data read-write unit is used for concurrently accessing the metadata, corresponding to the at least two read requests, according to the access authority allocated to the at least two read requests by the access request control unit, and thereby realizing concurrent access to the metadata.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a metadata server, a metadata concurrent access system and a method. Background technique [0002] With the rapid development of computer applications, distributed file systems are more and more widely used. In distributed file systems, metadata servers can sequentially receive read and write requests from data servers and clients for the same file through mutual exclusion locks. . When multiple data servers and multiple clients send access requests to the same metadata server at the same time, the mutex in the metadata server will queue all requests to ensure the consistency of file data, that is, only one access at a time The request has access rights, making concurrent access to the metadata impossible. Contents of the invention [0003] The invention provides a metadata server, a system and a method for concurrently accessing metadata, and realizes concurre...
