Embodiment approach

[0111] The read client sends a query request to all storage devices in the storage device cluster after receiving a query request failure response from the metadata server in the metadata server cluster; or

[0112] The read client sends a query request to all storage devices in the storage device cluster while sending a query request to at least one metadata server in the metadata server cluster.

[0113] The following describes in detail the processing process of data writing in the cloud storage system of the embodiment of the present invention, such as Figure 9 shown, including the following steps:

[0114] Step 901, the write client selects a metadata server from the metadata server cluster according to the set strategy;

[0115] Specifically, the set strategies include but are not limited to one or more of the following methods:

[0116] The write client selects the metadata server with the smallest load according to the load of each metadata server in the metadata se...

Abstract

The invention relates to the technical field of cloud storage, in particular to a method, equipment and a system for data processing of cloud storage, aiming to solve the problems that the data writing is long in processing time and low in efficiency in the prior art. The method provided by the invention comprises the following steps: a metadata server of a metadata server cluster selects storage equipment from a storage equipment cluster when receiving a writing request from a writing client, and metadata corresponding to to-be-written data is generated and stored according to the stored information and parameter information; and the writing client is reminded to write the to-be-written data into the corresponding storage location of the selected storage equipment according to the stored information, when a writing request success response and the stored information are sent to the writing client. According to the embodiment of the invention, the writing processing failure caused by not returning the successful response to the client when a certain data server can not work normally due to network and hardware failures, and other reasons is solved, the processing efficiency is improved, and the processing time is shortened.

Description

technical field [0001] The present invention relates to the technical field of cloud storage, in particular to a data processing method, device and system for cloud storage. Background technique [0002] Cloud storage system refers to a system that integrates a large number of different types of storage devices in the network through application software to work together through cluster applications, grid technology, or distributed file systems, and jointly provide data storage and business access functions. The architecture of cloud storage system is as follows: figure 1 As shown, it includes: a client 10, a metadata server cluster 11 and a storage device cluster 12, wherein the metadata server cluster 11 includes at least one metadata server, and the storage device cluster 12 includes at least one storage device. [0003] The data writing process of the existing cloud storage system is: [0004] The client 10 establishes a connection with any metadata server (such as the...
