Problems solved by technology

[0004] In order to solve the problem of uneven load distribution, the present invention provides a method for migrating objects, including the following steps: counting the loads of multiple object storage devices OSDs, and the metadata server MDS regularly queries the load information of multiple OSDs; through the MDS analysis The load of multiple OSDs is sorted, and the first multiple OSDs with larger loads and the second multiple OSDs with smaller loads are selected; and some objects on the first multiple OSDs are migrated to the second multiple OSDs

Embodiment Construction

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of the present invention.

[0023] According to an embodiment of the present invention, a method of migrating an object is provided.

[0024] like figure 1 As shown, the method includes the following steps:

[0025] Step S101, count the loads of the OSDs of the multiple object storage devices, and the metadata server MDS regularly queries the load information of the multiple OSDs;

[0026] Step S103, analyze the loads of multiple OSDs by MDS and sort them, and select the first multiple OSDs...

Abstract

The invention provides a method and a system for migrating objects. The method includes the following steps: counting load of multiple OSDs (object storage devices), and regularly inquiring load information of the OSDs by a metadata server (MDS); analyzing the load of the OSDs through the MDS and sequencing, and selecting multiple first OSDs large in load and multiple second OSDs small in load; migrating part of the objects on the first OSDs onto the second OSDs. By the method and the system, dynamic migration of the objects can be realized to enable load of the server to be balanced, so that overall service capability of a server system is improved; even under circumstance of centralized access, service capability of the system can be maintained in a good state, so that average waiting time of client sides is effectively reduced, and user experience is improved.

Description

technical field [0001] The present invention relates to the field of computers, and in particular, to a method and system for migrating objects. Background technique [0002] In a large-scale storage system, the operating files are often localized. When the access is concentrated on some object storage devices OSD, the service capability of the system will drop rapidly. Therefore, in a distributed system, it is necessary to dynamically balance various The load of the OSD improves the overall service capability of the system. [0003] Aiming at the problem of uneven load distribution in the distributed system in the related art, when the access is concentrated, the service capability of the system is greatly reduced, and no effective solution has been proposed yet. SUMMARY OF THE INVENTION [0004] In order to solve the problem of uneven load distribution, the present invention provides a method for migrating objects, which includes the following steps: counting the loads ...
