Method for migrating non-distributed storage physical volume to distributed storage system through platform

Abstract

The invention relates to the technical field of cloud platform storage virtualization, and in particular to a method for migrating a non-distributed storage physical volume to a distributed storage system through a cloud platform. The method of the invention comprises the following steps: first acquiring non-distributed storage physical volume information; acquiring physical volume residing volume group information; determining whether the volume group has two or more than two physical volumes, and if the volume group has two or more than two physical volumes, executing migration procedure, and if the volume group does not have two or more than two physical volumes, the migration being determined to be failed; determining whether available space of the volume group is larger than the total space of the physical volume, and if the available space of the volume group is larger than the total space of the physical volume, continuing the migration procedure, and if the available space of the volume group is not larger than the total space of the physical volume, the migration being determined to be failed; reducing the volume group; local volume management releasing the physical volume; adding the physical volume as a storage object to the distributed storage system; finally the physical volume providing distributed storage service. The method of the invention addresses the problems such as that the planned storage plan is not suitable for user's using habits on the cloud computing platform, migration of physical volumes can only be operated manually, and the need for virtual machine migration or volume group deletion prior to migration. The method is applicable to the field of managing new planning of all kinds of storage virtualization types.

Description

technical field [0001] The invention relates to the technical field of cloud platform storage virtualization, in particular to a method for migrating a cloud platform non-distributed storage physical volume to a distributed storage system. Background technique [0002] Generally, the new cloud computing platform is difficult to plan the storage space, and the cloud servers with local storage, centralized storage and distributed storage each have their own advantages and disadvantages. For example, cloud servers with local storage are cost-effective, disk reads and writes do not depend on the network, but have low reliability and low disk reads and writes performance; cloud servers with distributed storage have high reliability and high performance, but rely on the network and greatly reduce Increase the pressure on network switches, and many customers are unwilling to buy expensive fiber optic switches; with the long-term development of cloud platforms, the following problem...

Problems solved by technology

[0007] The technical problem solved by the present invention is to provide a method suitable for migrating non-distributed storage physical volumes of cloud platforms to distributed storage systems, and to solve the problems of users who have planned storage schemes not suitable for cloud computing platforms, physical volume migration only Can be operated manually, need to migrate virtual machines or delete volume groups before migration, etc.
