Problems solved by technology

When the user's data is in megabytes (TB) or larger, the traditional expansion method takes a very long time
Huge data may not only be lost during the process of moving; any error in the process of moving will cause great harm to the user

Abstract

The invention discloses a method for expanding the capacity of a virtual hard disk, which is used for expanding the capacity of a first virtual hard disk assigned to a virtual machine in a first physical hard disk. The method for expanding the capacity of a virtual hard disk includes: providing a second physical hard disk, wherein the available capacity of the second physical hard disk is not less than the total capacity to be expanded; stopping the access operation to the first virtual hard disk; capacity of the second virtual hard disk; link the second virtual hard disk with the storage space of the first virtual hard disk; and run a virtual machine manager program to assign the second virtual hard disk to the virtual machine and restore the virtual machine's access to the second virtual hard disk Access operations.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a hard disk, in particular to a method for expanding the capacity of a virtual hard disk. Background technique [0002] Technologies such as Virtual Machine (VM) and Cloud Computing (Cloud Computing) that virtualize physical resources and provide them to users, as well as the benefits they bring, are attracting attention from all over the world. Among them, cloud computing is a new computing method based on the Internet (Internet), which can provide required computing for individual or business users through different services on the Internet. Cloud computing resources are virtualized, and physical resources are virtualized and provided to users through the Internet. Users do not need to understand the details of physical resources and their related configurations in the "cloud", do not have corresponding professional knowledge, and do not need to directly control physical resources. Use...
