What update, specifically? With multiple boot targets, in general any updates to boot process must be updated on the individual targets separately.

You need to install GRUB on all of the mirrors, two in this case. Issue the commands `grub-install /dev/sda` and `grub-install /dev/sdb`, assuming the mirrors are /dev/sda and /dev/sdb. I am given to understand the ZFS pools will also need to be duplicated.
