You could use gconcat, but you'd have to partition, label and newfs this new
combined device which would render your current data unreadable. And on a
concatenated disk the risk of failure is increased. If one of the two drives
dies, you'll lose all data. If you want to combine disks, use some form of
RAID to protect yourself from a dying disk. :-)
