Thanks for the responses :) You have convinced me to add another 2 drives to use as a dedicated boot mirror pool.
I've got room so why not. I'll just use the excess space on the mirror as a place to backup files for more redundancy.

I always like to have physically separate root disks. If you have space for them I'd get a couple of smaller disks to act as a root mirror (e.g., I have 2 x 250GB drives for a mirrored rpool) and then use all of your big data disks in a data pool. Just to second what he said. I have 2x160Gb disks in a mirrored root pool, and (at the moment) 4x500Gb disks in a RAIDZ. Much safer as if something takes out my root, like a dud update or the like, my data space is safe(r). Also, IIRC, ZFS works better when given *entire* disks to work with, rather than slices. Cheers, Gary B-) Just to confirm what the others have said, it is not a recommendation of SUN (even though it is possible) to use pools on individual slices. Using a root pool on separate disks would be a much better option, if available and is a SUN recommended configuration.
