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 distributed storage system comprises a data storage node Nthat receives a write success response returned by a hard disk that provides the storage address. The data storage node Nreturns a write success response to a client. The client receives the write success response returned by the data storage node N, and the client returns a write completion response to a host.

Distributed storage system and computer program product

A data storage method implemented by a storage node in a distributed storage system includes receiving first data of a first strip in a first stripe, wherein the first stripe comprises a first plurality of strips, receiving second data of a second strip in a second stripe, wherein the second strip comprises a second plurality of strips, wherein a first logical address of the first data is the same as a second logical address of the second data, and generating a record indicating that the first data reaches the storage node before the second data.
