Method and apparatus for transmitting host and backup mechanism data of distributed file system

Abstract

The invention discloses a method and an apparatus for transmitting host and backup mechanism data of a distributed file system. The method and the apparatus are used for solving the problem of an influence on business processing efficiency of a host metadata server in the prior art. The method comprises the steps that: a host metadata server establishes a connection with a backup metadata server after determining that the backup metadata server is started up; the host metadata server receives a data request sent by a client, determines a corresponding backup type according to the data request, performing data processing on data carried by the data request, and stores the processed data in a specified memory; and the data in the specified memory is sent to the backup metadata server according to the backup type. The data is asynchronously copied, so that the data operation efficiency of the host metadata server is improved on the basis of ensuring transmission reliability.

Description

technical field [0001] The invention relates to the field of master-backup mechanism data transmission, in particular to a master-backup mechanism data transmission method and device of a distributed file system. Background technique [0002] In a distributed storage system, the descriptive information of data and information resources is called metadata, and the management of metadata generally adopts a centralized metadata service model. [0003] In order to improve the reliability of metadata, to avoid the failure of the entire distributed storage system when the metadata server fails for some reason. Therefore, it is necessary to provide a backup metadata server for the metadata server to take over the work of the primary metadata server that has a problem, so as to ensure the normal operation of the entire system. In order to ensure the strong consistency between the primary and secondary metadata servers, data transmission between the primary and secondary metadata se...

Problems solved by technology

[0008] Embodiments of the present invention provide a data transmission method and device for a master-backup mechanism of a distributed file system, which is used to solve the problem in the prior art that when synchronous copying data is used between the master and the backup, it will consume time and signaling, resulting in The working efficiency of the system is reduced. When using the method of asynchronously copying data, multiple handshake protocol operations are required, which increases the burden on the network and affects the business processing efficiency of the main metadata server.
