(reads code).
Ahhh. You are using version-1 superblocks aren't you? That code only
works for version-0.90 superblocks. That was careless of me. It
shouldn't be hard to make it work more generally, but it looks like it
will be slightly more than trivial. I'll try to get you a patch in
the next day or so (feel free to remind me if I seem to have
forgotten).
Thanks for testing and reporting this problem.

I am very sorry, but it wont works with .9 superblocks also :( We
missing something small, but important here. Before you start to code.
mdadm was running in monitor mode, and reported a Fail. mdadm is the
latest version, 2.6.2.
