lvrename can rename an actively mounted device?  Is it supposed
to do that?

That sounds a bit strange.  I mean if I rename a network device, I'd
have to take down the interface before renaming it.  I'd think with a
disk partition unmounting it would be, at least, prudent?  Is it really
not necessary?
