Hmm, ok.

It is, unless you stay with a low-version ZFS (don't upgrade your pools) or
pick one branch (Oracle, vs. .. ??)

You should be able to boot an installer disk and boot your installed system
from the installer. It would be better to have someone nearby walk you
through this. I've done it a bunch of times and it is simple, but not simple
to talk about.

grub normally doesn't install on both drives of a root mirror. One thing you
should do when you get your system back is installgrub on both drives. Then
again, if you can't select boot order with your BIOS this might not help.

I think your system is probably fine, I don't know why you lost your
bootability. But this sometimes happens on earlier S10. There used to be a
bunch of disk driver issues that affected SATA drives.
