[Samba] Issues accessing ZFS-shares on Linux

I think it may have something to do with my disks being encrypted. This
issue happened after updating systemd to version 236, ZoL to 0.7.4 and
kernel to 4.14.
I have always mounted the pool manually by first opening LUKS-encrypted
disks and after that issuing zpool import tank.
Is there any way to still use systemd to manage smbd or do I have to
just always start it manually?
This is how the pool has been set up:
