I ran newfs -v on it when I first created the volume on vinumdisk0. I didn't do it when I attached the second subdisk. (The volume has been in use a while and wiping the FS is not really an option.) vinum(8) says that "It is possible to increase the size of a concatenated vinum plex ..." so I would think that it could handle it.
