Correct, it's 1.0 metadata and raid10.

yeah, I made a 1.0 raid10 with 4 LVs, and couldn't trigger the bug. Of
course, that array was also much smaller.

I've had the array for a while (the superblocks with -E show a creation
time of Wed Jun 16 14:25:08 2010). If I had to take a guess, I'd guess
it was created with the Debian squeeze alpha1 installer... So probably
2.6.30 or 2.6.32.

I'd guess it was created by doing 'mdadm --grow --bitmap internal' at
some point after the array was created, but I'm not sure. Could have
been created with the array.
