To use growfs you must have space in the slice contiguous with
the partition you want to increase in size. It cannot just grow
anywhere. You really did not want to move things using dd.
You really wanted to build the new file systems to the sizes you
want on the new disk and then use dump/restore to to the new
partitions.
First, fdisk the new disk and put the MBR on it and create your
one slice on it and flag that as bootable.
Then, use disklabel (in 4.xxx, bsd label in later versions of FreeBSD)
to create your slices and also make it write out the boot sector.
There is a block of examples in the disklabel/bsdlabel man page
that tells how to use dd to make sure a drive is clean
and then fdisk to make one slice with MBR and finally two disklabels
to create the bootable partition and then to edit the partition
table for all the partitions. That group of commands is just what
you need.
Then, do a newfs on each partition created (except swap) and
then make a mount point for them. Mount the 'a' partition on
something like '/newroot' for example and then run dump/restore
to copy root
cd /newroot
dump 0af - / | restore -rf -
Do the same dump/restore thing for each of the partitions/filesystems.
Make sure you cd in to the base of each mounted new filesystem
before doing the dump/restore and replace the '/' in the dump to
be each filesystem - for example, for /usr, make a /newusr mountpoint
mount it and then cd to /newusr and do 'dump 0af - /usr | restore -rf -'
When you get done, you will have a fully useable, bootable copy of your
machine on the new disk. Move the new disk to the primary boot
position in your boot chain and start it up.
By the way, those are pretty small drives. I don't see any
on the market nowdays less that 18 GB and more likely larger.
Maybe you need some new hardware.
