I ran a ‘zpool upgrade zroot’ then saw the following:
If you boot from pool 'zroot', don't forget to update boot code.
Assuming you use GPT partitioning and da0 is your boot disk
the following command will do it:
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da0
zroot is our boot volume but it’s made up of two mirrored disks: ada0, ada1
Please advise how I should run the above command without hosing our 10.1-RELEASE-p15 host.
