Abstract
A storage server stores data in a redundancy group of mass storage devices according to a data redundancy scheme. The redundancy scheme enables reconstruction of all data stored in the redundancy group if N or fewer mass storage devices in the redundancy group contain erroneous data, where N is at least 2. In response to determining that the redundancy group contains erroneous data, N−1 mass storage devices in the redundancy group can be specifically identified as containing the erroneous data.
