Abstract

The invention discloses a method and system for dynamic load balancing of metadata servers. The method comprises the steps that whether the source utilization rates corresponding to the metadata servers are larger than a first threshold or not is judged by detecting the source utilization rate of each metadata server in a metadata server cluster; if yes, a migration request is sent to a metadata management module, the metadata in the metadata servers corresponding to the source utilization rates larger than the first threshold is migrated into a second metadata server cluster, wherein the first threshold is the maximum allowable value of the source utilization rates, and the second metadata server cluster is a cluster of the metadata servers, corresponding to the source utilization rates smaller than the first threshold, in the metadata server cluster. Therefore, the dynamic uniform distribution of the metadata in the metadata servers is achieved, the dynamic load balancing of the metadata servers is achieved, and the performance of the metadata servers is improved.

Description

technical field [0001] The invention relates to the field of distributed cluster metadata servers, in particular to a method and system for dynamic load balancing of metadata servers. Background technique [0002] With the development of the Internet and the increase of Internet users, the data in the Internet has also expanded rapidly. Tens of thousands of data are generated every day, and a single computer is limited by hardware such as memory and CPU, which cannot meet the storage and computing requirements. [0003] Mass data storage emerges as the times require, among which distributed file system is an important technology for mass storage. The distributed file system stores data on multiple physically dispersed storage nodes, manages and allocates the resources of these nodes in a unified manner, and provides an interface for users to access the file system. Through the distributed file system, the massive data storage system can easily store PB-level data. Distrib...
