Yes and no, I ran the command, but it wasn't what I really wanted
and/or needed, so to speak.

Yes, the numbers all match.

Just a mistake when I added it.

I'll give it a try, but first a question and FYI.  Earlier Phil had me
ddrescue sde1 because it had pending sectors I believe.  Should I use
sde1 or sdz1(ddrescued version)?

Also when this whole thing started. md127_raid process was using 100%
cpu, but nothing seemed to be happening, No numbers changed, nothing
that I could tell anyway.  Any suggestions on if the same thing
happens when I run the revert-reshape? Could one of my libraries be
behind a version somewhere?
