I have a small web page that describes the relative location of RAID segments in a RAID-5 array, for the four different Linux RAID-5 algorithms (right/left synchronous/asynchronous). http://www.accs.com/p_and_p/RAID/LinuxRAID.html Some information on how the parity is maintained is on a related page I have. This information is in the RAID-4 section, but the parity generation is the same for RAID-4 and RAID-5. http://www.accs.com/p_and_p/RAID/BasicRAID.html That's two pieces of the puzzle. Is that enough? Good luck.
