Problems solved by technology

However, adding management nodes or adding backup management nodes will increase the project cost, and adding management nodes or adding backup management nodes can only ensure the normal operation of the cloud storage system when some management nodes fail, but cannot guarantee that all management nodes fail Or the cloud storage system runs normally when the network of the management node cluster is abnormal

Abstract

Embodiments of the invention provide a data writing method and apparatus, a data reading method and apparatus, and a cloud storage system. The data writing method comprises the steps of receiving a data writing request by an access node; when an available management node cannot be obtained, identifying domain identifier information contained in the data writing request, and according to the domain identifier information, querying a pre-stored index, wherein the index contains a corresponding relationship between a resource pool and the domain identifier information; identifying the target resource pool matched with the domain identifier information, wherein each resource pool contains at least one storage server; and from the at least one storage server contained in the target resource pool, determining one storage server as a target storage server, and writing to-be-written data in the target storage server. According to the data writing method and apparatus, the data reading method and apparatus, and the cloud storage system, the cloud storage system still can normally run when all management nodes are faulted or a management node cluster network is abnormal, and the additional cost does not need to be increased.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and device for writing and reading data, and a cloud storage system. Background technique [0002] Cloud storage is a new concept extended and developed on the concept of cloud computing. It is an emerging network storage technology. A large number of different types of storage devices work together through application software to jointly provide a system for data storage and business access functions. [0003] The cloud storage system is a distributed system with a master-slave architecture, and the master node, that is, the management node, plays a vital role in the normal operation of the entire system. Once the management node fails, all services of the entire system cannot be carried out normally. For example, when an access node in a cloud storage system receives a data write request, the access node needs to send the data write request to the man...
