Unfortunately, gmirror and other GEOM classes are not supported by our
installer.

The safest way to do what you want is to:

	# gmirror label <name> ad1
	create slices and partitions on /dev/mirror/<name>
	create file system
	copy data from ad0 to <name>
	change /etc/fstab to boot from /dev/mirror/<name>s1a or something
	reboot
	# gmirror insert <name> ad0
