Embodiment Construction

[0018] The method of the present invention will be described below with reference to the drawings and specific embodiments.

[0019] Quickly synchronize network connections such as figure 1 As shown, the fast synchronization network is connected to each set of service nodes, and the specific implementation form of the synchronization network is not limited. It can be a physically independent management network, or the same physical network as the data network.

[0020] Node monitoring methods such as figure 2 As shown, the state collection and synchronization methods in the synchronization group are divided into the following steps:

[0021] Step S1, the head node constructs a state collection group according to the connection status between the current node and other nodes and whether messages have been sent within the monitoring interval. If messages have been sent within the interval, there is no need to send a state collection command to the node; if If no message is sent, the c...

Abstract

The invention provides a distribution type file system monitoring mechanism method based on a rapid synchronization network, and the method can be used for rapidly synchronizing the state of a service on each node in the system. With regard to N nodes, the whole system can finish monitoring and synchronization of the state of the whole system by only sending 3N information, so that the expandability of the N nodes is better and the N nodes can be expanded along with the scale of the system. Meanwhile, by utilizing a dynamic owner changing method based on election, single-point failures do not exist. Meanwhile, according to a communication state between the system and the other nodes, the quantity of the synchronization information is further compressed and the expenditure for monitoring is reduced.

Description

Technical field [0001] The invention relates to a communication system of a parallel file system, in particular to a distributed file system monitoring method based on a fast synchronization network. Background technique [0002] The communication system in the distributed system is of great significance as the communication basis between the nodes of the system. Since each node in the distributed system may fail, in order to improve the availability of the system, it is necessary to quickly detect and locate the fault after the node and service fail, so as to facilitate the subsequent fault recovery and processing of the system. Therefore, the speed and accuracy of monitoring and detection of distributed systems become important. The traditional system monitoring method sends service status monitoring messages between nodes. This method can detect system failures. However, as the scale of the system expands, its interference with normal messages in the network will rise sharply...
