You should mount your ra0e on the point (relative to ra0a) where
you want the /usr-partition to be:

	# mkdir /mnt/usr
	# mount /dev/ra0e /mnt/usr

now you can copy the files over into /mnt, the files in the usr-subtree
go into /mnt/usr ie. ra0e, the rest goes into /mnt ie. ra0a.

Your ra0a-partition has 20000 blocks, which is ca. 10MB.
This should be enough to hold /var, /etc, /bin, /sbin etc.,
but it's not big enough to hold the data in /usr also. By mounting
ra0e on /mnt/usr, the /usr-data are transferred to their correct
destination and don't use diskspace from ra0a.

PS: If you already have a directory /mnt/usr, then you should delete
    it's contents first (rm -rf /mnt/usr/*) before mounting ra0e into
    this directory. Any files in the directory /mnt/usr won't be 
    accessible while ra0e is mounted into that directory, but they're
    still there and thus use disk-space.

PPS: Another possiblility could be that you're copying the shared
     binary for each file you copy. The shared binary is quite big
     (ca. 800KB) and thus fills up the disk quite fast. Try using 
     tar instead of cp.
