Distributed storage volume creation method, system and device and computer medium

Abstract

The invention discloses a distributed storage volume creation method, system and device and a computer medium. The method comprises the steps: obtaining a target distributed storage volume creation request; judging whether the target distributed storage volume creation request is legal or not; if the target distributed storage volume creation request is legal, selecting a volume ID in an unused state from preset volume IDs as a target volume ID according to a preset requirement; based on the target volume ID, creating a target volume according to the target distributed storage volume creationrequest, and marking the state of the target volume ID as an in-use state; judging whether the target volume is successfully created or not, and if the target volume is successfully created, marking the state of the target volume ID as a used state; if the target volume fails to be created, marking the state of the target volume ID as an unused state, wherein the initial state of the preset volumeID is unused. According to the volume creation method and device, the unused state, the in-use state and the used state are set for each volume ID, so the volume ID conflict condition is avoided, andthe volume creation success rate can be increased.

Description

technical field [0001] The present application relates to the technical field of distributed storage, and more specifically, to a method, system, device and computer medium for creating a distributed storage volume. Background technique [0002] Distributed storage system is to disperse and store data on multiple independent devices. Traditional network storage systems use centralized storage servers to store all data. Storage servers become the bottleneck of system performance and the focus of reliability and security, which cannot meet the needs of large-scale storage applications. The distributed network storage system adopts a scalable system structure, uses multiple storage servers to share the storage load, and uses the location server to locate and store information. It not only improves the reliability, availability and access efficiency of the system, but also is easy to expand, distributed storage The system is also being used more and more. [0003] In the appli...

AI Technical Summary

Problems solved by technology

[0003] In the application process of the distributed storage system, it is sometimes necessary to create distributed storage volumes. However, since there are multiple distributed storage nodes in the distributed storage system, multiple distributed storage nodes may require the creation of distributed storage volumes at the same time. In this case, volume ID conflicts may occur, causing the creation of distributed storage volumes to fail.
