The installer won't allow installing w/o stomping on the existing label. Oracle's documentation states that it is not possible to boot 10 or 11 from disks over 2 TB. So I'm debating partitions on 4x2 TB disk or a separate root pool disk. I'm leaning in the 4x2 direction at the moment as that should cover what I really need for the next 2-3 years. I have such high confidence that will work, I'll probably order a single 2 TB disk to test it. I'm very burned out on chasing down compatibility issues and winding up w/ expensive shelfware. I burned up the whole day yesterday trying to get 151a7 to play nice w/ a 3 TB Toshiba USB drive. It works, but not nice enough to be usable. But it's an improvement. I couldn't get 151a5 to create a pool at all. So it wound up on the shelf for 6 months. Have Fun!
