The invention provides a fault processing method, a fault processing device and a storage medium. The method comprises the following steps: judging whether first terminal equipment has a fault or notin the process of executing a first part of services of a distributed service; under the condition that a fault occurs, storing the calling information of the first terminal device in a distributed file system, and storing the distributed service log set of the first terminal device in a distributed file system, wherein the distributed service log set of the first terminal device comprises a plurality of logs generated by the first terminal device in a predetermined time period associated with the time when the fault occurs. According to the method and the device, the call chain can be recorded by using the call chain identifier, a main line is provided for tracking and positioning of the service fault, and the positioning capacity of the equipment after the fault occurs is improved. The collection of related logs is triggered through distributed faults, a heartbeat mechanism does not need to be arranged to detect the abnormal state of equipment, and the influence on normal services isreduced.

The invention discloses a service switching method, device and system and a storage medium. The method comprises the following steps: if heartbeat information of a main node is not received within the effective time of a main lock corresponding to the main node, controlling the main lock to be invalid; lock grabbing information sent by a service node is received, and the service node comprises at least one of a main node and a backup node; a new main node is selected from service nodes according to the lock grabbing information, and the main node is used for processing an information service request sent by a client side. According to the embodiment of the invention, the fault service node is found in time through the heartbeat information, the service is quickly switched according to the lock grabbing information under the condition of ensuring that the service node is available, the service switching efficiency is improved, the influence of the fault service node on the information service can be reduced, and the information service quality is enhanced.
