I added a warning to it last week). A ZFS mirror is probably a better solution than ZFS on top of a gmirror. Looking back on this thread, I'm confused. The subject says MBR, but then the text talks about GPT. If possible, avoid MBR and the "partitions inside a partition" mess of EBR or MBR slice/FreeBSD partitions and just use GPT. Grub2 is supposed to handle it.
