Method for cloud platform distributed physical volume object migration to non-distributed storage

Abstract

The invention relates to the technical field of cloud platform storage virtualization, and particularly relates to a method for cloud platform distributed physical volume object migration to non-distributed storage. According to the method, distributed physical volume object information is acquired firstly; distributed storage system information is acquired; whether the number of storage objects of a distributed storage system is greater than 2 is judged, and the migration process is continuously performed if the judgment result is yes, or migration fails; whether available space of the distributed storage system is greater than physical volume total space is judged, and the migration process is continuously performed if the judgment result is yes, or migration fails; the distributed storage system eliminates physical volume objects; physical volumes are created through local volume management; a volume group is expanded; and finally the physical volumes provide a non-distributed storage service. The problems that the planned storage scheme is not adaptive to the use habits of users of a cloud computing platform, operation of physical volume migration is performed through a manual mode and the migration method is not universal can be solved so that the method can be applied to the field of management of replanning of various 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 distributed physical volume object to a non-distributed storage. 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 problems are br...

AI Technical Summary

Problems solved by technology

[0007] The technical problem solved by the present invention is to provide a method suitable for migrating distributed physical volume objects on cloud platforms to non-distributed storage, and to solve the problem that the originally planned storage scheme does not adapt to the user's usage habits of cloud computing platforms, and physical volume migration can only Manual operation, migration methods are not universal enough, etc.
