Intra-cluster node troubleshooting method and device

A troubleshooting device, comprising:

• a transceiver configured to communicate with a detection node;
• a memory storing instructions;
• and
• a processor in communication with the transceiver and the memory, the processor executing the instructions to perform:
• obtaining fault detection topology information of a cluster, fault detection being performed on one node in the cluster by at least one other node in the cluster, the fault detection topology information comprising a fault detection relationship between the detection node and a detected node in the cluster;
• receiving a fault indication message from the detection node, the fault indication message indicating unreachability from the detection node to the detected node;
• determining a sub-cluster of the cluster based on the fault detection topology information and the fault indication message, with nodes belonging to different sub-clusters of the cluster being unreachable to each other;
• and
• determining a working cluster based on the determined sub-cluster.

A non-transitory computer readable medium storing computer-readable instructions that when executed by a processor, cause the processor to perform operations comprising:

• obtaining fault detection topology information of a cluster, fault detection being performed on one node in the cluster by at least one other node in the cluster, the fault detection topology information comprising a fault detection relationship between a detection node and a detected node in the cluster;
• receiving a fault indication message from the detection node, the fault indication message indicating unreachability from the detection node to the detected node;
• determining a sub-cluster of the cluster based on the fault detection topology information and the fault indication message, with nodes belonging to different sub-clusters of the cluster being unreachable to each other;
• and
• determining a working cluster based on the determined sub-cluster.
