The sysadmin responsible for our zfs systems just left. WE don't have
passwords to them, I tried following Sun's documentation here:
http://docs.sun.com/app/docs/doc/817-2271/zfsboot-1?l=en&a=view
and booted to failsafe mode, but was unable to zap out the shadow file
entries, see below:

Dariusz,

I don't know why you have both temporary mount points /a and /mnt.
I can't test this myself but you should try to do a zfs umount -a
and then remount like this:

# zfs umount -a
# zfs set mountpoint=3D/mnt rpool/ROOT/zfsBE
# zfs mount rpool/ROOT/zfsBE

Then, follow the steps here substituting /mnt for /a:
