Dear Neil,

thanks for your answers and the great job you are doing for all of us

And of course you are right. In order to reshape our raid10-array
I upgraded to mdadm 3.3 and the newest longterm kernel that was
available. That was a couple of weeks ago and the newest 3.14.x
kernel was 3.14.12 :-(

Kind regards
