    • Methods, computing systems and computer program products implement embodiments of the present invention that include arranging multiple storage devices as a RAID array and receiving, from a given storage device storing a dataset, a number of error messages exceeding a threshold. A mirrored subset of the dataset is retrieved from the given device, and a calculated subset of the dataset is retrieved from remaining devices in the RAID array. In a first embodiment, the mirrored subset is created first, and the calculated subset includes a relative complement of the mirrored subset with respect to the dataset. In a second embodiment, the calculated subset is created first, and the mirrored subset includes a relative complement of the calculated subset with respect to the dataset. The mirrored and the calculated datasets are stored to an additional storage device, and the given device is replaced with the additional device in the RAID array.
    • 方法,计算系统和计算机程序产品实现本发明的实施例,其包括将多个存储设备布置为RAID阵列,并且从存储数据集的给定存储设备接收超过阈值的多个错误消息。 从给定设备检索数据集的镜像子集,并从RAID阵列中的其余设备检索数据集的计算子集。 在第一实施例中,首先创建镜像子集,并且所计算的子集包括相对于数据集的镜像子集的相对补码。 在第二实施例中,首先创建所计算的子集,并且镜像子集包括相对于数据集的所计算子集的相对补码。 镜像和计算的数据集存储到另外的存储设备,并且给定的设备被替换为RAID阵列中的附加设备。
