Abstract

The invention discloses a data migration method and device of a cloud storage technology in a cloud technology scene and a storage medium, and particularly relates to technologies of cloud storage, cloud reading, cloud block storage and the like. The method comprises the steps that under the condition that the remaining capacity of a first data storage warehouse is smaller than a target capacity threshold value, a first cloud hard disk to be subjected to data migration is determined in the first data storage warehouse; a second cloud hard disk is created in a second data storage warehouse, andthe capacity of the second cloud hard disk is the same as that of the first cloud hard disk; under the condition that a first access request for the first cloud hard disk is obtained, the first access request is set as a second access request for the second cloud hard disk; and the data in the first cloud hard disk are migrated to the second cloud hard disk, and a second access request is performed on the second cloud hard disk. The technical problem that in the data migration process, the integrity of data migration is guaranteed but normal access to the cloud hard disk cannot be guaranteedis solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a data migration method and device and a storage medium. Background technique [0002] In recent years, the application of cloud storage has become more and more extensive. Among them, in specific application scenarios, in order to isolate fault domains, a group of physical storage devices is divided into a logical storage unit, which is a storage warehouse, and a storage warehouse often has thousands of A cloud hard disk (Cloud Block Storage, referred to as CBS) that provides persistent block-level storage services for cloud virtual machines (Cloud Virtual Machine, referred to as CVM). When there is a risk that the capacity of the storage warehouse is about to be overwhelmed (if the storage space of the storage warehouse is exhausted, the system will refuse to accept new io writes, which will seriously affect the user's business, which can be called the risk of warehouse capacit...
