Thanks for the steps, Laszlo. I got as far as creating a freebsd slice on da1
(both da1 and da2 have been low-level formatted).
Now I have two questions:
1) When creating the slice on da1, I specified to use the entire disk, but
there are 2 unused sections -- one before and one after the new slice (please
see attached file). Should I start over and specify a smaller size? What size
should I specify?:'
2) About creating partitions on da1: You specified to add partitions to the
slice (/dev/da1s1a, /dev/da1s1b,/dev/da1s1c etc.).
Please note:
a) The entire FreeBSD filesystem is on da0.
b) I want to use the entire da1 disk for users on Windows clients to store
files/documents on. I also want the mirror disk (da2) to be backed up regularly.
Do I need to create more than one partition on da1? What are the requirements
for naming partitions in this situation?
Thanks!

appreciate a concise set of steps for doing this right the first time.
1. First of all, you should install the base system on da0 and boot it.
(Leave da1 and da2 untouched)
2. Create a slice on da1 ("fdisk"). The name of the new slice will
probably be "da1s1". (You will find this inside sysinstall) I found that
sometimes I had to use a bit smaller slice than the available space,
because equally looking disks are not always equal. (Not kidding!)
3. Use disklabel editor to add partitions to the slice
(/dev/da1s1a,/dev/da1s1b,/dev/da1s1c etc.) and format them with newfs as
needed.
4. Change loader.conf, add this line:
geom_mirror_load="YES"
5. Execute these:
gmirror load
gmirror label -v -b round-robin gm0 /dev/da1
6. Carefully rename all references in /etc/fstab
/dev/da1s1X becomes /dev/mirror/gm0s1X (where X can be a,b,c,d etc.)
7. Reboot
8. Check your mirror with "gmirror list" and "gmirror status", and see
if your filesystems are mounted with "df".
9. Add da2 to your mirror with this command:
gmirror insert gm0 /dev/da2
Please ask others, as I did not try this and I'm not 100% sure it will
work. But I think it should.
Best,
Laszlo

Ahhh...imagining that irresistible "new car" smell?
Check outnew cars at Yahoo! Autos.Prepare disks da1 and da2 (after low-level format):
Run FDISK from systinstall:
DISK name: da1 FDISK Partition
Editor
Disk Geometry: 1115 cyls/255 heads/63 sectors = 17912475 sectors
Offset Size(ST) End Name PType Desc Subtype
Flags
0 17916240 17916239 - 12 unused 0
After Create slice (size = 17916240, type = 165):
Offset Size(ST) End Name PType Desc Subtype
Flags
0 63 62 - 12 unused 0
63 17912412 1912474 da1s1 8 freebsd 165
17912475 3765 17916239 - 12 unused 0
