If I were you I would format every 1.5TB drive like this: * 6GB slice for the root fs
As noted in another thread, 6GB is way too small. Based on actual experience, an upgradable rpool must be more than 20GB. I would suggest at least 32GB; out of 1.5TB that's still negligible. Recent release notes for image-update say that at least 8GB free is required for an update. snv111b as upgraded from a CD installed image takes > 11GB without any user applications like Firefox. Note also that a nominal 1.5TB drive really only has 1.36TB of actual space as reported by zfs. Can't speak to the 12-way mirror idea, but if you go this route you might keep some slices for rpool backups. I have found having a disk with such a backup invaluable... How do you plan to do backups in general?
