Problems solved by technology

[0004] When the nodes of the storage cluster and the Zookeeper server are disconnected from each other due to a sudden disconnection of the network, the corresponding temporary node of the Zookeeper server will also be automatically deleted, and the watcher will receive the deletion notification, and will think that the node of the storage cluster is faulty , leading to misjudgment; when the number of watchers and connections in Zookeeper itself is too large, performance bottlenecks will occur, resulting in the overall unavailability of fault detection for storage cluster nodes

Abstract

The invention discloses a fault detection method and system for a storage cluster, and relates to the technical field of computers. A specific embodiment of the method comprises the following steps: performing cyclic detection on each storage node in a storage cluster through a plurality of detection nodes; and for each storage node, judging whether the storage node fails or not according to the detection results of the plurality of detection nodes. According to the embodiment, survival detection can be carried out on the storage cluster node without using a Zookeeper server, fault misjudgment of the storage cluster node caused by network flash, network blockage and the like is avoided, and the defect that fault detection is not available on the whole is avoided.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a storage cluster fault detection method and system. Background technique [0002] Now enterprises use storage clusters to provide external services, such as using Redis (remote dictionary service, a key-value database) cluster to provide external services. In order to monitor the failure of nodes in the Redis cluster, the existing solution is to use Zookeeper (a distributed Open source distributed application coordination service) temporary nodes to monitor node survival, that is, let each Redis node connect to the Zookeeper server, and create its own corresponding temporary nodes, and the detection party adds watcher monitoring (Zookeeper Provided a monitoring mechanism), when the Redis node fails, the corresponding temporary node on Zookeeper will be automatically deleted, because the detection party has added watcher monitoring to the temporary node, so it will receive a de...
