Abstract
Disclosed is a method of reliably operating a RAID storage system. A first block of data is striped across a plurality of drives following a CRUSH algorithm. The first block of data is again striped across a second plurality of drives to a D'+P′ stripe and placed on free drive space following the CRUSH algorithm. The data is written in an asynchronous fashion and possibly at a time when system utilization is low.
