Abstract
A method, computer program product, and data processing system for continuously writing new data to a redundant array of independent storage devices without interrupting the writing of new data to the array to reconstruct missing data from a failed device or failed media is disclosed. A fault-tolerance scheme using multiple independent parity values is used to record data to the array. In the event that one of the volumes in the array fails, the remaining volumes continue being written to, but with fewer data or parity values being employed. The failed volume can then be reconstructed following the completion of writing the media set currently being written.
