Abstract

The invention provides a storage volume online migration method and device and a storage volume online migration system. The method comprises the steps of receiving a migration instruction; migratingdata of source volume to target volume according to a migration instruction; under the condition that a business writing instruction is received in the migration process, synchronously writing the business data into the source volume and the target volume; and under the condition that all data of the source volume is migrated to the target volume, converting the execution object written with the business instruction from the source volume to the target volume, and deleting the source volume. According to the method, in the data migration process, the business data is synchronously written intothe source volume and the target volume, so that the execution of the business instruction is not interrupted, the online migration of the storage volume is realized, and the problem that the onlinemigration of the storage volume cannot be realized in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of online migration, and in particular, relates to a method and device for online migration of storage volumes, a computer-readable storage medium, a processor, and a system for online migration of storage volumes. Background technique [0002] Snap based migration is based on cow snapshots. This type of migration is based on the snapshot mechanism. The snapshot of the virtual machine contains all the stored data. The migration process of the snap based virtual machine is to continuously take snapshots of the virtual machine - migrate snapshots, Until a snapshot smaller than the predetermined value is obtained, the virtual machine is temporarily stopped at this time, and then the last difference data is quickly migrated to the target, and then the virtual machine is started on the target machine. The characteristic of this solution is that taking a snapshot will cause performance loss, and the snap...
