What I did do (after still not finding any disk errors) was pvmove --abort, then I restarted again. This time it copied the remaining two parts entirely successfully. I've no idea how the mirroring/kcopy is implemented. Does it retry if a read fails? I was wondering if the self test initiated on the drive could have caused a read to fail (though I'm sure it shouldn't).
