Hi!

On the contrary, because of the switch from FreeBSD ZFS to
OpenZFS, the bootcodes needs to be updated! It's unfortunate
that no message is displayed 8-(
The problem is, finding out which bootcode needs to go where etc.
It depends if your system boots from the EFI partition or
from the freebsd-boot partition. And how your system is
partitioned.
I have some notes for gpart filesystems:
- check with
gpart show
This system has both (!):
partition 1 is efi
partition 2 is legacy boot
=> 40 4000797280 ada0 GPT (1.9T)
40 409600 1 efi (200M)
409640 1024 2 freebsd-boot (512K)
410664 984 - free - (492K)
411648 18874368 3 freebsd-swap (9.0G)
19286016 3981510656 4 freebsd-zfs (1.9T)
4000796672 648 - free - (324K)
- To update the EFI:
mount -t msdos /dev/ada0p1 /mnt
cd /mnt/efi/boot
mv BOOTx64.efi BOOTx64.efi-old
cp /boot/loader.efi BOOTx64.efi
cd /
umount /mnt
- To update the legacy boot:
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 2 ada0
- If efi is not mountable ? create a msdosfs:
newfs_msdos /dev/ada0p1
mount -t msdos /dev/ada0p1 /mnt
mkdir /mnt/efi/boot
cp /boot/loader.efi /mnt/efi/boot/BOOTx64.efi
umount /mnt
