Embodiment Construction

[0030] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0031] image 3 It is a flowchart of a migration processing method of a metadata server according to an embodiment of the present invention. Such as image 3 As shown, the method includes: step S302 to step S306,

[0032] S302: Obtain the configuration information of the target server that the original server needs to migrate to;

[0033] In this step, the source of the configuration information includes two ways: the original system information of the distributed file system where the original server is obtained from the above-mentioned original server; the user configuration migration information determined according to the migration scenario. Where the user selects different migration scenario...

Abstract

Provided are a metadata server migration processing method and device, the method comprising: obtaining the configuration information of a target server that an original server is to be migrated to; writing the configuration information into an in-memory database of the target server, and generating a configuration file of the target server according to the configuration information; uploading the in-memory database and the configuration file to the target server for distributed deployment. The technical solution of the present invention prevents abnormal service operation caused by the damage to or the location change of the metadata server, significantly reduces manual operation errors and decreases the time for migration, thus improving migration efficiency.

Description

technical field [0001] The present invention relates to the field of data storage, and more specifically, to a metadata server migration processing method and device. Background technique [0002] With the explosion of unstructured data, distributed file systems have entered a golden age of development. From high-performance computers to data centers, from data sharing to Internet applications, distributed file systems have penetrated into all aspects of data applications. However, for most distributed file systems, metadata and data are usually separated, that is, control flow and data flow are separated, so as to obtain higher system scalability. Therefore, metadata management becomes very important. [0003] The distributed file system includes the following servers: Directory Tree Server (Directory Tree Server, referred to as DTS), file location register (File Locate Register, referred to as FLR), file access client (File Access Client, referred to as FAC) and File Ac...
