Abstract: The present disclosure provides a replica processing method based on a raft protocol. The method includes: for a node to be processed corresponding to a raft replica group, determining a replica to be cleaned corresponding to the node, the raft replica group including a first node and at least one second node; for the node, obtaining replica configuration information of the raft replica group, the replica configuration information including one or more primary replicas stored by the first node and one or more secondary replicas stored by the at least one second node; and for the node, determining whether the replica configuration information includes the replica to be cleaned, if yes, reserving the replica to be cleaned, and if no, deleting the replica to be cleaned. The present disclosure also provides a replica processing node, a distributed storage system, a server, and a computer-readable medium.
