Like a filesystem superblock, your LUKS header probably fits neatly well
within a single chunk, so provided that particular disk was in the right
position in the array, it'd quite happily try and open it up.
Unfortunately if the other drives are not quite right it will just fail
to find the filesystem inside the container, or worse..
I don't consider everything to be right until it'll pass a fsck -n.
