Abstract: According to a distributed storage system-based data processing method and a storage device provided in the present disclosure, a storage node is selected as a primary storage node in a partition in the distributed storage system. During data reading, after receiving a read I/O request from an initiator, the primary storage node determines whether a target data object that the read I/O request requests to read on the primary storage node is trustworthy; and when the target data object is trustworthy, directly reads the target data object from the primary storage node and returns the target data object to the initiator of the read I/O request.
