Embodiment Construction

[0034] Embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0035] The embodiment of the present application provides a virtual volume creation method, mounting method, and device. When the virtualization management platform creates and allocates virtual volumes, it allocates more storage space at the fixed location of the virtual volume as volume operation control domain space. It is used to record the information of whether the virtual volume is occupied. In this way, the problem that the virtual volume is mounted by two or more virtual machines at the same time can be effectively solved, the business reliability is greatly improved, and the business loss is reduced.

[0036] The embodiments of the present application can be widely used in the field of cloud computing and virtualization. After the deployment of business cloudification or virtualization in various industries, the method of the embodiment of t...

Abstract

The invention discloses a virtual volume creation method and apparatus, and a virtual volume mounting method and apparatus, relates to the technical field of cloud computing, and aims to solve the problem of influence on normal operation of businesses when a same virtual volume is mounted by multiple virtual machines. The method comprises the steps that a virtual management platform receives a request of creating a virtual volume; and the virtual management platform creates the virtual volume based on the request, wherein the virtual volume comprises a first storage space, and the first storage space is used for recording information on whether the virtual volume is occupied or not.

Description

technical field [0001] The embodiments of the present application relate to the technical field of cloud computing, and in particular, to a virtual volume creation method, mounting method and device. Background technique [0002] At present, business and information systems in various industries are being deployed in virtualization. In a virtualization deployment, user data is stored in a virtual volume, which can be regarded as a logical storage resource, such as a logical disk. The virtualization management platform uniformly manages the shared storage resource pool where each user's business runs. The virtualization management platform allocates a virtual volume of a certain size to the user on demand from the shared storage resource pool, and mounts the virtual volume to a virtual machine (Virtual Machine, VM) for the user to store system and application data. [0003] In the case of network abnormality or host abnormality, the virtualization management platform perfor...
