Abstract

The embodiment of the invention provides a data replicating method and a data storing system. The data replicating method comprises the following steps of: responding to a file reading request from a client; obtaining each file block number of a file to be read as well as the distribution information of each file block on a corresponding storage node; based on the distribution information and combined with the load degree information of the corresponding storage node, transmitting a whole set of file blocks to the client from multiple of storage nodes with matched load degree being lower than a first load degree threshold; and synchronizing all matched file blocks on the multiple storage nodes or transmitting the file blocks in queue to the client. As the embodiment of the invention is combined with the load degree information of the corresponding storage node and all the file blocks of the file to be read are distributed on corresponding nodes, the stability during high concurrency of the storage system is enhanced. Since the popularity of the file to be read is obtained dynamically and is stored in a dynamic distribution way, the capacities of the storage nodes are expanded on line and the user experience is further improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of computer information storage, and in particular to a data replication method and a storage system adopting the method. Background technique [0002] The rapid development of computer technology and network communication technology has made the global information storage volume increase rapidly at a rate of more than 30% per year. Network storage has become an inevitable trend in the field of storage technology, and broadcasting media information online through the network has become a normal life of users. Among them, a large-scale distributed file system built on the basis of an object storage structure can provide strong concurrent data processing capabilities. Therefore, metadata service management is very important in a large-scale distributed file system. [0003] However, the traditional metadata management only adopts static metadata segmentation and distributed storage, ...
