Node device, recovery operation control method and recovery operation control program

摘要

When a node device (10-1) has detected a system failure in a cluster system (1), it determines whether the node device (10-1) is an avoidance-override device. Then, when the node device (10-1) determines that the own node device is an avoidance priority device, the node device (10-1) transmits a request signal to a node device (10-2) other than the node device (10-1). The request signal is a signal for requesting a report about a normal state and an abnormal state of the node device (10-2). Then, the node device (10-1) determines whether to execute a recovery operation of the own node device or to avoid executing a recovery operation of the own node device based on the report from the node device (10-2)
