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.
