The embodiment of the invention provides a failure detection method and device for nodes in a cluster
system. The method comprises the following steps that: a first node judges whether a first
heartbeat message sent by a second node is received in preset time or not, wherein the first node is a neighbor node of the second node, and the first
heartbeat message is a
heartbeat message which is sent to each neighbor node of the second node in parallel by the second node; under the condition that the first node does not receive the
heartbeat message sent by the second node, the first node sends a request message to other neighbor nodes other than the first node in all the neighbor nodes of the second node; the first node receives response messages carrying reception states sent by the other neighbor nodes; and under the condition that the first node determines that other neighbor nodes do not receive the
heartbeat message according to the reception states, the first node determines that the second node fails. Through adoption of the failure detection method and device for the nodes in the cluster
system, the node failure detection efficiency can be increased.
