Abstract: A method describes that a lost first block in a first stripe is directly reconstructed based on a first result obtained from a target quantity of storage devices, so that there is no need to read an unlost block in the first stripe. The first block may be reconstructed provided that the target quantity of first results are obtained. An amount of data of the first result is less than that of the unlost block in the first stripe. Therefore, a data transmission process occupies less network bandwidth, and this improves block reconstruction performance.
