Hi Charles,
Works fine.
I did just that with my home system. I have 2x .5 TB disks which I
didn't want to dedicate to rpool, and I wanted to create a second pool
on those disks which could be expanded. I set up the rpool to be
100GB and that left me with a 400GB partition to make into an extended
pool (xpool). There are probably some down-sides to doing this, but I
have yet to come across them at this point.
The reason I did this is to get around the limitation on rpool which
restricts it to being simple mirrors which cannot be added to in a
striped configuration.
After that was set up I attached 2x 1 TB disks to the extended pool in
a mirrored configuration.
Check out my blog entry which explains exactly how to do this. The
system I used in the demo is inside VirtualBox, but I have real
hardware running in the configuration I mention. Using VirtualBox, I
worked out the finer bits, before trying it out on my live machine.

One really interesting bit is how easily it is to make the disk in a
pool bigger by doing a zpool replace on the device. It couldn't have
been any easier with ZFS.
I've even done a fresh install on this configuration just recently,
and other than being exposed for a bit while I broke the mirrors to
install a fresh copy of the OS, everything worked out alright. A few
snags with namespace collisions when I re-imported the original rpool,
but I'd already seen those before and wrote about them in another blog
entry.
If you have any questions, feel free to let me know.
Cheers,
Mike
Mike

I have a small system that is going to be a file server. It has two
disks. I'd like just one pool for data. Is it possible to create two
pools on the boot disk, and then add the second disk to the second
pool? The result would be a single small pool for root, and a second
pool containing the rest of that disk plus the second disk?
The installer seems to want to use the whole disk for the root pool.
Is there a way to change that?
