Abstract
Provided in the disclosed embodiments are methods and apparatuses for switching service nodes in a distributed storage system, the service nodes comprising a current service node and backup service nodes. The method comprises: monitoring response states of the service nodes to a service request; and if a response state of the current service node is abnormal, stopping communication between the current service node and the backup service nodes, and triggering a switching process for the current service node. In the case of a service timeout, service unavailability, service abnormality, or the like caused by a hardware failure or software defect, logic is checked with a service node that performs logical determination and data statistics collection for multiple factors affecting response states of service nodes, thereby achieving autonomous switching and recovery of the service nodes and improving service availability.
