Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0052] After research, the applicant found that storing files in the qcow2 format on centralized storage would lead to inaccurate planning of storage space usage. In order to solve the above problems, this technical solution proposes a method and device for streamlining virtual machine disks , including: create the virtual machine disk image in the preset logical volume, and calculate the actual disk size used in the virtual machine disk image when the current ...

Abstract

The invention discloses a method and device for streamlining a virtual machine disk, comprising: creating a virtual machine disk image in a preset logical volume, and calculating the actual volume in the virtual machine disk image when the current virtual machine disk image is qcow2 The size of the used disk; obtaining the size of the logical volume where the virtual machine disk image is located; and expanding the capacity of the logical volume according to the actual size of the disk used by the virtual machine disk image. It can be seen from this that the storage space is expanded according to the actual size of the disk used, thus improving the utilization rate of the disk space.

Description

[0001] This application claims the priority of the domestic application submitted to the China Patent Office on July 10, 2018, with the application number 201810750715.7, and the title of the invention is "A Method and Device for Streamlining Virtual Machine Disks", the entire content of which is incorporated herein by reference. Applying. technical field [0002] The invention relates to the field of data storage, in particular to a method and device for streamlining virtual machine disk images. Background technique [0003] In a virtualization system, in order to meet increasing storage requirements and improve storage efficiency, data is usually stored in a thin disk manner. Disk thinning can be understood as using the host file system hole technology to save the physical disk space occupied by the virtual machine disk to achieve on-demand growth. For example: Assuming that a thin virtual machine with a disk size of 100G is created, the initial physical space occupied by...
