A data processing method in a storage system and the storage system, and relates to the field of data storage technologies. A client first sends a data block in a stripe and metadata of the data block to a data storage node. The client then sends the metadata of the data block and a parity block to a parity storage node, to back up the metadata of the data block on the parity storage node. When the metadata of the data block is successfully backed up, the data block is written into a corresponding storage device based on a storage location indicated by the metadata. This reduces write operation time.

Data processing method and apparatus in storage system, and storage system

A stripe reassembling technique includes a stripe server that selects stripes; uses data chunks including valid data in the stripes S, S, and Sas data chunks in a new stripe S, and generates data of a parity chunk for data of the data chunks in Saccording to an erasure coding (EC) algorithm the same as that of S, S, and S; and stores the parity data of the parity chunk on a parity storage node.
