I have done this most of the time even though I know that growing
exists. I believe this a much safer approach if you do not have a
backup. However I do know that the linux raid code is very robust,
during a grow test I rebooted the machine while it was growing the
array and when the system came back up it continued where it left off.
I am almost certain that the filesystem was already expanded at that
