I had a similar use-case with zfs-fuse on Debian GNU/Linux several years ago. I recall writing an import script that ran during system startup and an export script that ran during system shutdown. This was prior to systemd and fairly easy to do. But, I have also used the force '-f' option for various zpool(8) commands more often than I care to admit. ;-) David
