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.

Embodiment Construction
[0051] By adopting the technical solution of the present invention, it is possible to effectively avoid the consumption of time and signaling when the method of synchronously copying data between the master and the backup exists in the prior art, resulting in a reduction in the working efficiency of the system. 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 master metadata server.
[0052] An embodiment of the present invention provides a data transmission method of a master-backup mechanism of a distributed file system, and preferred implementation modes of the present invention will be described in detail below with reference to the accompanying drawings.
[0053] refer to image 3 As shown, the specific processing flow of a data transmission method of a master-backup mechanism of a distributed file system provided by an ...

The invention discloses a master-backup mechanism data transmission method and device of a distributed file system, which are used to solve the problem in the prior art which affects the business processing efficiency of a master metadata server. The method includes: the primary metadata server establishes a connection with the secondary metadata server after determining that the secondary metadata server is started; after receiving the data request sent by the client, the primary metadata server determines the corresponding backup type according to the data request, and The data carried in the data request is processed, and the processed data is stored in the designated memory; and the data in the designated memory is sent to the backup metadata server according to the backup type. In this way, the use of asynchronous data replication improves the efficiency of data operations on the master metadata server 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...
