Ok, I'm a bit confused.

I was running 2.6.38 when I replaced the drives and grew the array.
Apparently growing went fine, because I was using the array for a
couple of weeks. But it didn't write the correct metadata (0.90), thus
reassembling after boot fails (or rather is the wrong size).

I tried booting with 3.0.0, 3.2.0 and 3.5.0 with exactly the same results.

I feel that no matter what kernel, as long as the metadata's wrong, I
can't assemble it correctly, correct?

Cheers,
Marks.
