Abstract
A method of efficiently preventing data loss, specifically a RAID 5 write hole, in data storage system by storing valid parity information at the storage controller level during data write operations. The method employs the use of redundant data structures that hold metadata specific to outstanding writes and parity information. The method uses the redundant data structures to recreate the write commands and data when a system failure occurs before the writes have completed.
