Embodiment Construction

[0021] Such as figure 1 as shown, figure 1 It is a flow chart of a method for quickly copying distributed file system data proposed by the present invention.

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] A method for fast copying of distributed file system data, comprising the following steps:

[0024] S1: packaging and copying information, wherein the copying information includes target file information and source file information;

[0025] S2: Send the copy information to the metadata server;

[0026] S3: After receiving the copy request, the metadata server identifies the source file and prepares the target file;

[0027] S4: After the metadata operation is successful, prepare a data copy request: source object information and target object information, and send the request to the data server;

[0028] S5: After receiving the request, the data server identifies the source object ...

Abstract

The invention discloses a method for quickly copying data of a distributed file system. The method comprises the following steps: sending data information needing to be copied to a metadata server; After receiving the request, the metadata server side prepares a target object and sends a data copying request to the data server side; And the data server realizes copying of the source file object data to the target file object data, and returns an execution result. According to the method for quickly copying the data of the distributed file system disclosed by the invention, quick copying of mass data is realized by shortening an IO path of data transmission.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a method for quickly copying distributed file system data. Background technique [0002] With the ever-increasing demand for data storage, the amount of file data managed by enterprises also increases. When the business needs to copy the data in the file system cp, the data content is read from the source file to the client, and then the data is written to the target file. This processing method has a long IO path and low data copy efficiency. . [0003] Based on the above problems, therefore, for those skilled in the art, how to realize fast copying of massive data in a distributed file system is a technical problem that needs to be solved urgently. Contents of the invention [0004] Based on the technical problems existing in the background technology, the present invention proposes a method for fast copying of distributed file system data, which realizes fast copying of m...
