Embodiment Construction

[0035] The application will be described in further detail below in conjunction with the accompanying drawings.

[0036] In a typical configuration of the present application, the terminal, the device serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0037] Memory may include non-permanent storage in computer readable media, in the form of random access memory (RAM) and / or nonvolatile memory such as read only memory (ROM) or flash RAM. Memory is an example of computer readable media.

[0038] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random acce...

Abstract

The purpose of this application is to provide a method and device for cloud disk mode switching; obtain the cloud disk mode switching request of the target cloud disk; based on the cloud disk mode switching request, re-match each data block of the target cloud disk corresponding hard disk. Compared with the prior art, the switch of the cloud disk mode in this application can be based on the existing hard disk deployment of the target cloud disk, thereby effectively saving storage resources; at the same time, since this application re-matches the hard disk for each data block Therefore, it is not necessary or only necessary to dump part of the data, and the entire switching time will be greatly shortened compared with the overall migration of cloud disks in the prior art; in addition, In this application, after the cloud disk mode is switched, there is no need to remount the cloud disk, so the continuity of the business can be effectively guaranteed.

Description

technical field [0001] The present application relates to the field of computers, and in particular to a technology for cloud disk mode switching. Background technique [0002] Usually, the cloud computing market will provide users with available high-efficiency cloud disks and ordinary cloud disks, but users can only choose one cloud disk mode at a time, either high-efficiency cloud disks or ordinary cloud disks. In the prior art, if a user purchased a high-efficiency cloud disk but wants to convert it to a normal cloud disk due to business needs, he can only create a new normal cloud disk and migrate the data on the high-efficiency cloud disk to the normal cloud disk , and then delete the original high-efficiency cloud disk; on the contrary, if the user purchases a normal cloud disk and wants to convert it into a high-efficiency cloud disk, he can only create a high-efficiency cloud disk and migrate the data on the normal cloud disk to the high-efficiency cloud disk. Then...
