sorry, I was confusing terms. I was expecting to see similar to output
of zfs list from both zpools instead of just zpool0.

(just rebooted the system.)

OK here's zpool status:

# zpool status
  pool: zpool1

yes.

If I run zfs mount -a, everything zfs is mounted as expected. I'm
wondering if at bootup, when zfs mount is called (I suppose it must be
called from somewhere), whether it needs to specify -a. I would not know
the first place to look though.

thanks,
