It's not pretty, and it slows the process down something chronic but hopefully it will make the process bulletproof. While I'm here I'm looking at trying to add raid-6 support also. I have had a pretty good trawl through the raid-6 kernel code and given raidreconf does not do anything with parity blocks it looks pretty similar to raid-5 from that respect. Are there any gotchas that anyone can think of I should look out for that may trip me up with the difference between raid5 & 6 ? I figure if you could do an easy conversion between raid-5 and raid-6 it might speed up testing and adoption of raid-6. Regards, Brad
