specific Embodiment approach

[0039]In a distributed storage system, a volume includes volume information and volume data. Volume data is user data stored in the volume. Volume information is used to record basic information about the volume, including volume name, size, volume ID, created user, and creation Time, access rights, belonging fault domain, belonging resource pool, volume version number, etc.; when users read data, they find the storage location corresponding to the volume data through volume information, and then read it. During the storage process, the volume information and Volume data is equally important. Losing any of them will cause users to be unable to read data normally. Therefore, in order to solve the problems of insufficient fault tolerance and low data reliability in volume information management of distributed storage systems in the prior art, the present invention Provides a volume information management method in a distributed storage system, and stores volume information and volume ...

Abstract

The invention discloses a volume information management method in a distributed block storage system, and the method comprises the following steps: S1, carrying out the fragmentation of storage nodesstored in a distributed block, obtaining slices, and configuring a copy for each slice; S2, uniformly distributing all slices and copies thereof on each storage node, wherein a plurality of slices andcopies form a volume; S3, writing the volume data and the volume information into a volume, wherein the volume information comprises a version number, a name, creation time, capacity and a type of the volume; and S4, the volume information server periodically polls all the storage nodes, and summarizes polling results to obtain latest volume information. The invention further comprises a distributed block storage system, volume information and volume data are stored in the storage nodes together, the reliability of the volume data and the volume information is ensured by establishing slice copies, and the volume information server periodically polls all the storage nodes, so that the reliability of the volume data and the volume information is ensured. The problems of insufficient fault-tolerant capability and low data reliability in volume information management of the distributed storage system are avoided.

Description

Technical field[0001]The invention belongs to the field of computer information security, and more specifically, relates to a distributed storage system and a volume information management method thereof.Background technique[0002]In recent years, distributed storage technology has developed rapidly, and its practical application in various IT infrastructures has become increasingly widespread. Its main driving force comes from the storage and processing of massive data, the resource pooling and cloudification of IT infrastructure, etc. Strong demand, and a significant reduction in overall cost. As the forefront of mobile Internet and Internet of Everything technology applications, the telecom service operator industry is extremely sensitive to the above-mentioned needs, and has listed the distributed replacement of traditional storage as the focus of IT infrastructure construction.[0003]Volume information management is one of the core technologies of distributed storage systems. Vol...
