Embodiment Construction

[0033] There are multiple implementations of the present invention, and here a common cloud platform is taken as an example to illustrate one of the implementation methods, such as figure 1 , 2 As shown, the specific implementation process is as follows

[0034] 1. Obtain the distributed physical volume object information, the code is as follows:

[0035]

[0036] 2. Get distributed storage system information, the code is as follows:

[0037]

[0038] 3. Whether the distributed storage system has more than 2 storage objects, the code is as follows:

[0039]

[0040] 4. Whether the available space of the distributed storage system is larger than the total space of the physical volume, the code is as follows:

[0041]

[0042]

[0043] 5. The distributed storage system removes physical volume objects, the code is as follows:

[0044]

[0045] 6. Local volume management creates physical volumes, the code is as follows:

[0046]

[0047] 7. To expand the ...

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...
