Fairly simple problem, I think, but I can't seem to get my head around a fix.
I'm on Ubuntu 18.04.3 and mounting zfs volumes with mongo-data at boot correctly with the config below in /etc/systemd/system/multi-user.target.wants.
[Unit] Description=ZFS startup target [Install] WantedBy=multi-user.target
Problem is that this happens after the mongod service is started, making mongod fail.

I read up about the
After directives, but I'm not confident I understand them well enough to play around with them.
