FreeBSD10-Stable Boot Failure with ZFS root

So I recently upgraded my 10-Stable machine at home to get some of the latest fix-ups. I forgot to update the boot code but I figured it would be a big deal since I was going from 10-stable to 10-stable. After rebooting I was greeted with “ZFS: unsupported feature: com.delphix:hole_birth” followed by no bootable zpools found. Ugh.

Downloaded the latest stable memstick image and booted off it to update the boot code.

gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0

Moral of the story? If you don’t update the boot code on a zfs root machine during an upgrade you’re going to have a bad time.

  1. This helped me out, thanks! Epic POLA fail for sure.

    Note that 10.0R is too old, but 9.3-BETA worked for me.
