Stumped by gpart and gmirror, trying to set up RAID1 (10.0-Beta3)

I'm using 10.0 beta 3.

I'm trying to learn and understand how to set up a RAID1 array.
 I'm using two thumbdrives as the "disks" on my notebook.  The
dmesg for the notebook is at the end of this message.

I've been following the example in The Handbook, section 19.4.2.
Creating a Mirror with Two New Disks

Here's a log of the comamnds and their results:

=== begin log ===============

[root at a20m /etc]# gmirror load

[root at a20m /etc]# gmirror label -v gm0 /dev/da0 /dev/da1
Metadata value stored on /dev/da0.
Metadata value stored on /dev/da1.

[root at a20m /etc]# gpart create -s MBR mirror/gm0
gpart: geom 'mirror/gm0': File exists

[root at a20m /etc]# gpart show mirror/gm0
=>      1  1981438  mirror/gm0  MBR  (967M)
        1       31              - free -  (16K)
       32  1981407           1  fat32  (967M)

[root at a20m /etc]# gpart delete -i 1 mirror/gm0
mirror/gm0s1 deleted

[root at a20m /etc]# gpart create -s MBR mirror/gm0
gpart: geom 'mirror/gm0': File exists

[root at a20m /etc]#  gpart add -t freebsd -a 4k mirror/gm0
mirror/gm0s1 added

[root at a20m /etc]# gpart show mirror/gm0
=>      1  1981438  mirror/gm0  MBR  (967M)
        1       31              - free -  (16K)
       32  1981376           1  freebsd  (967M)
  1981408       31              - free -  (16K)

[root at a20m /etc]# gpart create -s BSD mirror/gm0s1
mirror/gm0s1 created

[root at a20m /etc]# gpart add -t freebsd-ufs  -a 4k -s 2g
gpart: autofill: No space left on device

[root at a20m /etc]# 

=== end log ==============

I cannot seem to get past the "gpart: autofill: No space left on
device" error message.

I know I must be missing something obvious, but I am blinded by
my closeness to the problem.

What am I doing wrong?
