Problems solved by technology

[0004] However, when system disks with the same image file are created multiple times or in large numbers concurrently, the block storage service will send multiple requests to the image file service to download the image file. It is occupied on a large scale, which greatly interferes with the normal operation of other businesses and reduces the efficiency of creating system disks

Abstract

The embodiment of the invention discloses a method, device and equipment for creating a system disk in a cloud computing system and a storage medium, and the method comprises the steps: receiving a volume creation request for a to-be-created system disk in the cloud computing system, wherein the volume creation request comprises the identification of a mirror image file of the system disk; querying a block storage service used by the cloud computing system according to the identifier; when it is inquired that the mirror image file corresponding to the identifier exists in the block storage service, copying the mirror image file to the first target volume of the block storage service. In this way, it can be avoided that the network bandwidth is occupied on a large scale in the system disk creation process of the cloud computing system, and then the system disk creation efficiency is improved.

Description

technical field [0001] The embodiment of the present application relates to the technical field of cloud computing, and relates to but not limited to a method, device, device and storage medium for creating a system disk in a cloud computing system. Background technique [0002] At present, when a cloud computing system creates a system disk, it is usually implemented through a block storage service used by the cloud computing system. The block storage service is a resource management system service that is responsible for providing persistent block storage resources to virtual machines. By encapsulating multiple storage nodes corresponding to the block storage service, a unified driver is provided, and the drivers of different storage nodes are further reused. Thus, the management of different block storage resources is realized. The main core of the block storage service is the management of volumes, allowing the processing of volumes, volume types, and snapshots of volum...
