(In reply to Toomas Soome from comment #12)
I've upgraded the machine to 12-stable, and now it won't boot even with
copies=2.  So, not great.  I am currently booting using the install CD's
kernel, but that isn't a good long-term solution.

Is there any way to add a partition table (or some other kind of metadata that
the loader can read) retroactively?  If not, we *really* should teach zpool not
to allow adding an unpartitioned disk to the root pool (it already doesn't let
you remove devices from the root pool claiming that GRUB can't handle them, but
I'm not using GRUB so I don't care and there's no way to override this).

I tried adding a new disk, installing a partition table, and adding the
partition to the pool, but when I tried to remove da1 I got the aforementioned
error about GRUB, so I reverted the pool to a checkpoint.
