you must patch your kernel with the latest raidcode for this to work. you are
using a kernel with the old raidcode in it, but trying to use the new tools on
it.
get latest tools and raid patches from www.redhat.com/~mingo/
apply patch, build new kernel with the raid levels you need built in (not
modules) and follow the howto from there.
also note: you should not specify, IIRC, raid-disk and failed-disk on the same
disk. a device is either failed or raid. not both.
