That's what I was afraid of. /dev/sb1 is already in use. Fdisk doesn't
really know anything about LVM (other than the partition label). You
need to inspect the output of vgdisplay and lvdisplay to see what's
going on. You may not actually have an unused drive available to
expand /home.

Another graphical way to explore your disks is the "palimpsest"
utility, which from the menu is just called "Disk Utility".
