You didn't supply any argument to -Z at all, or to be precise, you supplied /dev/md6 as the argument, whereas you should have put in the array size. Also, another thing I have noticed lately is, that _some_ short options seem to be somehow oddly broken on my system and not accepting arguments, even if they are supposed to be. If the segfault persists after using the correct syntax, try using the long opts instead. I was planning to dig more into this bug myself, so I might just kick self to do it now.
