man gmirror
man newfs
man mount
man fstab
man smb.conf
man samba

gmirror label -b load sambavol /dev/da1 /dev/da2
newfs -U /dev/mirror/sambavol
mkdir /sambavol
mount /dev/mirror/sambavol /sambavol
echo '/dev/mirror/sambavol /sambavol ufs rw 2 2' >> /etc/fstab

The samba config depends a log on how you want to use the share and handle 
authentication and permissions, etc. The sample config file has most of what 
you need.  Here's a starting point for a section to share a /sambavol 
directory with a samba share name of sambavol:

[sambavol]
   path = /sambavol
   browseable = yes
   writable = yes
   printable = no

You will of course need a correctly configured global section and you'll 
probably want additional entries in the volume section like "public", "guest 
ok", "only guest", etc.
