摘要： Disclosed is a method and system of determining a data block of a RAID level 6 stripe that has corrupted or incorrect data. For each data block of the stripe, a reconstructed data block is created using the other data blocks and the P syndrome data block. The reconstructed data block and the other data blocks are used to create a new Q syndrome data block. The new Q syndrome data block and the stored Q syndrome data block are compared. If the new Q syndrome data block and the stored Q syndrome data block match, the data block is marked as being suspected as having corrupted or incorrect data. This process is repeated for every data block in the stripe. If there is only a single suspected data block, the reconstructed data block is stored as a replacement of the suspect data block in the stripe.

摘要翻译：公开了一种确定具有损坏或不正确数据的RAID级别6条带的数据块的方法和系统。对于条带的每个数据块，使用其他数据块和P校正子数据块来创建重建的数据块。重建的数据块和其他数据块用于创建新的Q校验数据块。比较新的Q校正数据块和存储的Q校验数据块。如果新的Q校验数据块和存储的Q校验数据块匹配，则数据块被标记为具有已损坏或不正确的数据。对条带中的每个数据块重复此过程。如果只有一个可疑的数据块，则重建的数据块被存储为条带中的可疑数据块的替换。
