Data reconstruction method and device applied to disk array system and computing equipment

The invention provides a data reconstruction method and device applied to a disk array system and computing equipment, and belongs to the technical field of storage. In the technical scheme provided by the invention, a part of data with relatively high reliability in the faulty disk which breaks down in the disk array system is directly copied to the new disk, only unreliable data in the faulty disk is reconstructed, and the reconstructed data is written into the new disk, so that replacement of the faulty disk is realized. The data reading and processing amount during reconstruction can be greatly reduced, the data reconstruction time is shortened, and the data reconstruction efficiency is improved. 本申请提供了一种应用于磁盘阵列系统的数据重构方法、装置及计算设备，属于存储技术领域。在本申请所提供的技术方案中，通过将磁盘阵列系统中发生故障的故障盘中的一部分可靠性较高的数据直接复制到新盘，而只对该故障盘中的不可靠的数据进行重构，并将重构后的数据写入新盘，以实现故障盘的更换，采用这种方式，可以大大降低了重构时读取和处理的数据量，缩短了数据重构时间，提高了数据重构效率。
