1. A data processing method for a distributed storage system, wherein the distributed storage system comprises a master control server, a slave control server and a plurality of storage servers, the method is performed by the slave control server of the distributed storage system and comprises:
transmitting, in an initial startup stage, a first request for acquiring data copy information to each storage server of the plurality of storage servers, to newly create mapping data;
periodically transmitting, to each storage server, the first request for acquiring the data copy information; and
updating the mapping data in the slave control server based on the data copy information returned by each storage server in response to the first request, which the mapping data indicates a correspondence relationship between the data copy information and the storage server.
