I'd say use gvinum. It's a bit tricky....actually, it's VERY tricky.
You have to get the geometry of the shared volume precisely right on the
120GB drive to match the 80GB drive, then you can allocate the rest of
the free space.
Honestly, you *could* cheat here. :) I think....
Set up your 80GB drive. We'll call it /dev/ad0.
Plug in your 120GB drive but don't do anything to it. We'll call it
/dev/ad1.
dd if=/dev/ad0 of=/dev/ad1
Now, set up gvinum as though they were of the exact same geometry, and
get your mirror going. Then, go back and modify the drive label of ad1,
and allocate the rest of the space on that disk. You'll want to have
gotten the REAL drive geometry of /dev/ad1 ahead of time, because (if I
recall...) you're going to have to change c: to the correct geometry,
then add partitions using space above and beyond what you have on ad0.
Does that make sense at all? Perhaps you should work through setting
up a normal gvinum mirror before going this route...

Hi all,
I unfortunately have 2 uneuqally sized SATA disks to set up a mirrored
shared folder: 80GB and 120GB. On the 120GB I plan to set up this way:
/temp 2GB (double the system memory)
/shared 80GB
/ 38GB
I plan to mirror /shared onto the 80GB. It won't be bootable, but I can
always mount it onto another FreeBSD machine.
I've read some articles on mirroring on non-equal disks, notably:
http://people.freebsd.org/~rse/mirror/
My question is: is there an easier way to do this? The example looks
quiet daunting for a noobie FreeBSD admin like me.
Appreciate any feedback on this. Thanks.
