That was supposed to say "a degraded RAID5+1".

Right. Doing it all automatically would be great, but involves some kernel work. What I was suggesting is that one administratively stop an array built conventionally, and manually start a degraded RAID1 for each component. It seems that is possible using "--build". Then one can manually assemble the RAID5+1 from those RAID1s, and proceed with the disk-by-disk replacement while the array is online. Looks as if that ought to be possible. I'll have to give it a try, as soon as I have an afternoon to tinker [say, ... mid-summer :-/].
