raid10 issues after reorder of boot drives.

[likewhoa <likewhoa@xxxxxxxxxxxxxxxx>]

I have a strange issue on my raid10 8x400GB array. I cannot assemble my
array anymore and it's gotten to a point that I don't know what to do to
recover my data. I was hoping I could get some advice on it. Below is
some info which I hope will help troubleshoot this issue.
