Abstract: Various embodiments provide a storage cluster configuration change method, an apparatus, a computer system, and the like. In a storage cluster that uses a consensus replication protocol, when half of storage nodes become faulty, if it is determined that at least one storage node exists in the storage cluster after the fault, and a latest log index number of the storage node is greater than or equal to an index number of a committed log provided by the storage cluster for a client, an arbitration module sends a forced cluster configuration change instruction to a fault-free storage node. The forced cluster configuration change instruction is used to instruct the fault-free storage node to change local cluster configuration information.

Abstract: Embodiments of this disclosure provides a heartbeat information sending method and apparatus, a heartbeat information processing method and apparatus, and a node. One example method includes: determining at least one heartbeat receiving node in which at least two follower data blocks corresponding to at least two leader data blocks in a heartbeat sending node are located; and when the at least one heartbeat receiving node is a single heartbeat receiving node, sending heartbeat information of the heartbeat sending node to the single heartbeat receiving node, where the heartbeat information of the heartbeat sending node is obtained after respective heartbeat information of the at least two leader data blocks are combined.

Abstract: The present disclosure provides a heartbeat information sending method and apparatus, a heartbeat information processing method and apparatus, and a node. The method includes: determining heartbeat receiving nodes in which at least two follower data blocks corresponding to at least two leader data blocks in a heartbeat sending node are located; and when the heartbeat receiving nodes are a same node, sending heartbeat information of the heartbeat sending node to the heartbeat receiving node, where the heartbeat information of the heartbeat sending node is heartbeat information obtained after respective heartbeat information of the at least two leader data blocks are combined.
