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
state: ONLINE
scan: scrub repaired 0 in 0h39m with 0 errors on Mon Feb 5 22:55:31 2018

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,
