Sheesh, everybody assumes I didn't do any research. I have one IDE
cable that runs the CDRom drive, so there's only room for one more
device there, and my system can't boot from USB.

David,
Buy an IDE flash DOM and a USB Flash DOM and mirror between those two...
Boot off of the IDE Flash DOM and the USB flash is there just in case.
If the USB device fails it's simple to replace it while the system is
running. If the IDE flash fails and the system is down (hardest case
scenario) you can simply replace the ide flash, boot form the installer
cd, zpool import -f syspool (from the USB flash), and then run the
appropriate replace commands. In some minutes you'll have your entire
pool back on a brand-new IDE flash again.
or you can explore iSCSI options... there is a way to boot from iSCSI
given the right network card.
or you can get an eSATA card and boot from an external eSATA drive
(there are eSATA flash sticks these days) You can even get an eSATA
multiplier and mirror between two eSATA drives on a single eSATA port.
or you can follow the quick instructions sent by Marcus Sundman in order
to setup the slice scheme you seem to really want. In this case I
suggest you _do_ figure it out because this is part of the extra admin
overhead you said you didn't mind. Instead of CTRL-A-C you can simply
use F1/F2 to switch between an extra shell to run format and the
installer window.
or you can install to a single IDE HD and then replace your CD-Rom with
another IDE HD and mirror post-install
or some combination of the above... iSCSI mirrored to IDE/IDE mirrored
to eSATA/eSATA mirrored to USB/... you could even do all of them and
setup a 4 -way mirror between iSCSI/eSATA/IDE/USB
or maybe even something else I haven't thought of... I'm sure FC has a
place in all of this.
The world is full of possibilities... especially the ones that aren't
recommended :)
Cheers,
-Tim
