mountroot prompt with error2, when trying to boot from a single drive in a 2-way mirror

[Yudi V]

I checked some popular image hosting websites, could not find any that did
not use javascript. I can send you the images via email.
This is reproducible on a clean install of 9.3 as well. I think it's a bug.

Here's the output of zdb -l /dev/ada2p3
