AI Technical Summary

Technical Problem

When existing data migration technologies handle online IO read and write requests, they can easily lead to data inconsistency and service interruptions, and cannot effectively process IO read and write requests, resulting in the risk of data loss.

Method used

Divide the data volume into multiple data blocks, and independently process it according to the migration status of each data block. The write operation data is temporarily stored through the target queue, and data migration is carried out without interrupting reading and writing IO to ensure data synchronization and consistency.

Benefits of technology

It realizes data migration without affecting business operations, avoids the risks of business interruptions and data loss in traditional migration methods, and improves the efficiency and disaster recovery of data migration.

Abstract

The invention provides a data migration method and device, electronic equipment and a medium, belongs to the technical field of computers, and aims to solve the problem that data migration cannot be carried out under the condition that services are not interrupted in a traditional data migration method. The method comprises the following steps: dividing a data section in a volume into a plurality of data blocks, wherein the data blocks represent data migration units; determining a migration state of a target data block executing migration in the plurality of data blocks; under the condition that the migration state of the target data block is write operation occupation, write operation data of the target data block is stored in a target queue, and the target data block is migrated to a target address from a source address; and under the condition that the migration state of the target data block is read operation occupation, reading the target data block from the source address, and migrating the target data block from the source address to the target address.
