Hi Alex, Sorry, I missed the 1.5 TB disk/boot issue previously.
A project is underway to provide booting for disks that are large than 1 TB. This project is outside of a future project to provide booting from an EFI-labeled disk. I agree that your best approach is to attach your second 500-GB disk to create a mirrored root pool and save the 1.5 TB disk for another day or another pool. You will be able to replace the 500-GB mirrored root pool with the 1.5 TB when booting from it is supported. What I'm thinking is that you will be able to upgrade your root pool with a release that supports booting from a 1.5 TB disk, then do the disk replacement.
