Problems solved by technology

[0003] However, traditional metadata management only provides metadata services by simply backing up metadata service nodes, without dynamic adjustments for hot metadata, and the smooth expansion of the metadata service system cannot be achieved

Abstract

The invention relates to a method and a system for load balancing of metadata management in a distributed file system. When the data structure of metadata, i.e. a directory tree, becomes hotspot metadata, the access heat degree of the directory tree is updated through adopting a mode of copying the metadata; when the load balancing degrees of service nodes of the metadata exceeds a preset value, partial working loads are transferred to underload nodes from overload nodes through adopting a mode of transferring the metadata; and the loading balancing among a plurality of the metadata service nodes is realized through the two modes. The system comprises an information communication module, a metadata operation module, a metadata service node management module, a metadata management module, a metadata strategy implementation nodule and a working load acquisition module. The invention improves the utilization rate of metadata service resources through the two modes of copying and transferring the metadata so as to achieve the purpose of load balancing, thus a metadata service system can be smoothly expanded.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a load balancing method and system for metadata management in a distributed file system. Background technique [0002] With the further development of information technology and the large-scale application of the network, the explosive growth of data has been brought, and the network storage has also brought great development. Among them, the large-scale distributed file system built on the basis of the object storage structure has strong scalability, high reliability, and can provide strong concurrent data processing capabilities. Therefore, metadata service management is very important in large-scale distributed file systems. important. Based on the study of cluster load balancing, designing and implementing a load balancing scheme that combines static load distribution and dynamic feedback redistribution of metadata management clusters has become an important topic ...
