It may also be the case that the containing partition must be expanded first using one or more incantations of gpart, bsdlabel and/or fdisk in some particular order. Looks like you'd be using just bsdlabel for your case. Note that in the case of UFS certain parameters are chosen at creation time that make growing more than an order of magnitude possibly suboptimal compared to a dump/restore. In your case I wouldn't worry about that.
