  • Method and apparatus for preserving data integrity in a multiple disk raid organized storage system
    Patent number: 5504858
    Abstract: A data storage system using a RAID array and a logging process and apparatus that identifies a parity block that may not contain the proper parity for its associated data blocks and which prevents such inconsistent parity information from being used in the regeneration of unavailable data. A small fraction of the blocks of each disk are dedicated to storing parity metadata bits. The parity metadata is associated with the parity blocks and identifies whether or not each parity block contains the proper parity information for its associated data blocks or may contain invalid information. The data integrity of the RAID array is preserved by preventing the generation of undetected corrupt data.
