Abstract: A method includes by a configuration center, receiving and executing a modification task, and locally storing modified state data and/or configuration data; generating a change task according to the modified state data and/or configuration data, and adding the change task into an asynchronous task queue corresponding to each storage node; receiving a heartbeat packet sent by the storage node; and taking out the added change task from the asynchronous task queue corresponding to the storage node, and adding the taken-out change task into a return message of the heartbeat packet to send the taken-out change task to the storage node; by a storage node, sending a heartbeat packet to a configuration center; receiving a return message of a heartbeat packet sent by the configuration center, the return message of the heartbeat packet including a change task; and adding the change task into an asynchronous task receiving queue for sequential execution.
