I have a similar problem, this time with a failing (now failed) disk that had freebsd-11-stable installed with the root-on-ZFS option. I manged to dd over ssh an image of the disk. However, I've not been able yet to mount the image to get the data. I think it's ZFS in the image that's causing the issue. I've tried to spin up the image in bhyve on another system. It gets past the demon graphic, tries to boot but drops to the mountroot or mfsroot (can't remember exactly) prompt. No matter what I enter there, it still won't boot. What it defaults to is what it used successfully when it was on the (now failed) hardware. Can anyone tell me how to mount and recover the image? many thanks, -- J.
