Embodiment Construction

[0024] Such as figure 1 Shown, the present invention is by Web server, front-end proxy server, storage controller, LVM function module, iSCSI function module, distributed file system, and the user can visit Web server through network, and the use of other modules is to be called by Web server according to user operation Yes, there is a strict call relationship between the web server and other functional modules.

[0025] Such as figure 1 , and the relationship between its modules is:

[0026] The storage controller includes LVM module and iSCSI function module, distributed file system client module, and storage controller module;

[0027] All user operations are initiated through web pages, including creating and formatting logical volumes, etc., and the web server accesses the reverse proxy server after receiving the request;

[0028] The reverse proxy server accepts the request from the web server, performs hash according to the user's IP address, and locates the designat...

Abstract

The invention relates to the technical field of distributed virtual disk management, in particular to a method for realizing high availability of a logical volume. A system comprises a Web server, a front-end agent server, a memory controller, an LVM (Logical Volume Manager) function module, an iSCSI (Internet Small Computer System Interface) function module and a distributed file system. A user accesses the web server through a network and other modules carry out calling in accordance with a calling relationship by the web server according to user operation. The invention solves the problem of single-point failure caused by a single storage controller in a storage system, provides creation, mounting and issuing of a multi-center management logical volume, ensures storage high availability through a snapshot technology, provides a disaster recovery function of the content of the logical volume, and can be widely applied to a storage management system of a cloud computing system.

Description

technical field [0001] The invention relates to the technical field of distributed virtual disk management, in particular to a method for realizing high availability of logical volumes. Background technique [0002] A distributed storage system is to disperse and store data on multiple independent devices. Traditional network storage systems use centralized storage servers to store all data. Storage servers become the bottleneck of system performance and the focus of reliability and security, which cannot meet the needs of large-scale storage applications. The distributed network storage system adopts a scalable system structure, uses multiple storage servers to share the storage load, and uses the location server to locate and store information. It not only improves the reliability, availability and access efficiency of the system, but also is easy to expand. [0003] Distributed storage controller, the storage controller is a storage system that centrally manages storage ...
