Abstract

The invention discloses a topological structure generating method for a distributed storage system. The topological structure generating method for a distributed storage system includes the steps: acquiring topological information in a topology update message by a main node; determining whether the topological information is the existing topology information; and if not, updating a topological list according to the topological information. Therefore, as a child node sends an LLDP (Link Layer Discovery Protocol) broadcast message carrying the topological information to the main node, the topological structure generating method for a distributed storage system can realize that an underlying protocol of topology discovery can be changed into a link layer protocol from TCP/IP (Transmission Control Protocol/Internet Protocol), thus expanding the application scene, and being able to acquire the latest topological structure in the local area network on the premise of guaranteeing partial failure or initialization scenes. Besides, the topological structure generating method for a distributed storage system optimizes the process of topology discovery without the demand for asking a customerto perform any operations, and can realize complete topology of the local area network and improve the user experience as the child node sends the LLDP broadcast message to the local area network actively. The invention also discloses a topological structure generating device and system for a distributed storage system, being able to implement the above technical effect.

Description

technical field [0001] The present invention relates to the technical field of distributed storage systems, and more specifically, to a method, device and system for generating a topology structure of a distributed storage system. Background technique [0002] Currently, in the distributed storage system, the generation of the topology depends on the socket method based on TCP / IP (Transmission Control Protocol / Internet Protocol, network communication protocol). Before generating the topology structure, it is necessary to ensure that all devices are correctly set with IP, and the application scenarios are very limited; in addition, this method cannot automatically generate the topology, and all node information needs to be filled in manually on the master node, which is not flexible enough. [0003] Therefore, how to quickly generate the topology structure of the distributed storage system is a problem to be solved by those skilled in the art. Contents of the invention [...
