Chris,

Based on my experience, it doesn't work to partition the underlying  
disk device da0, but rather the mirror device gm0. I've had a lot of  
success writing out new labels with

# bsdlabel -w /dev/mirror/gm0
# bsdlabel -e /dev/mirror/gm0

Editing the partition table by hand is a bummer, but for now, since  
mirror devices don't show up in fdisk/disklabel tools in /stand/ 
sysinstall, this is the only way I know of to do it.
