Let me rephrase, is the boot pool just one disk then ?
If you are tracking stable, and new features are added to the zfs pool
you will need to update the boot loader. Depending on how your system
boots, UEFI or traditional gpt, you will need to make updates manually.
e.g. on traditional gpt
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0 #assuming its
ada0
if you have a mirror then you need to do both disks in the mirror
If its efi, mount the msdos partiton and update the loader on it
.e.g on one of my boxes
mount_msdos /dev/gpt/efiboot0 /mnt
and copy a newer version of /boot/loader.efi over the old file in /mnt.
At this point you probably need to create a freebsd USB boot stick, boot
from it, import your pool, make the necessary changes based on whether
your boot disk is efi or gptzfsboot, export the pool etc.
If you get booted off the usb stick, post the output of "gpart show
ada0" if ada0 is the problem boot pool...
