Embodiment Construction

[0037] Such as figure 1 Shown, the present invention is made up of Web server, LVM functional module, iSCSI functional module, FTP functional module, and the user can visit web server through network, and the use of other modules is called by web server according to user operation, and web server and other functional modules There is a strict calling relationship between them.

[0038] Such as figure 1 , and the relationship between its modules is:

[0039] (1) LVM module and iSCSI-target are on the same physical machine; FTP-server and iSCSI-initiator are on the same physical machine; four functional modules can also be located on the same physical machine;

[0040] (2) All operations are initiated by web pages, including creating and formatting logical volumes, etc.;

[0041] (3) After receiving the user request, the web server calls other functional modules to realize corresponding functions;

[0042] (4) After logging in to the iSCSI-target on the iSCSI-initiator side,...

Abstract

The invention relates to the technical field of virtual disk management, in particular to a logical volume management method. According to the invention, a logical volume can be managed by means of a Web server, an LVM (Logical Volume Manager) functional module, an iSCSI (Internet Small Computer System Interface) functional module and an FTP (File Transfer Protocol) functional module; a user accesses the web server through a network; and the web server calls the LVM functional module, the iSCSI functional module or the FTP functional module to realize corresponding functions according to user operation. According to the logical volume management method disclosed by the invention, files in the logical volume are directly managed by using an FTP server, the problems of complexity and troublesomeness of managing the logical volume by executing a shell command are solved, and a user can operate self files more intuitionally. The logical volume management method disclosed by the invention can be widely applied to storage management of a cloud computing system.

Description

technical field [0001] The invention relates to the technical field of virtual disk management, in particular to a logical volume management method. 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] LVM logical volume management system, LVM (Logical Volume Manager) is a logical layer added between the disk partition and the file system to s...
