Ubuntu 18.04. LTS: ZFS-installer wrong partion on boot?

I hope someone can help me out with my ZFS problem or has some suggestions to use ZFS for the Ubuntu installtion or some other way.

I used the zfs-installer from here and successfully installed it with Ubuntu 18.04 LTS (it's a recommended version). I have configured two 1 TB disks in a ZFS mirror. But now I see with df -h that the system boots from the 12 GB (I guess the install) partion, which is also only on one disk.

tmpfs           3,2G     16K  3,2G    1% /run/user/121
tmpfs           3,2G     60K  3,2G    1% /run/user/1000

With gparted I can see th1 12 GB partition and the disk are partitioned in some way.

With zpool list I get that no pools are available.

How can I get this working? Will I have to change something in grub or zfs? How can I change something in zfs when I can't access the pool?

As side note: I have to use 18.04. The tools I have to use only work with that version. So using 20.04 with the Ubunut ZFS installer is no option.

Since [Eoan Ermine (Ubuntu 19.10)](https://ubuntu.com/blog/enhancing-our-zfs-support-on-ubuntu-19-10-an-introduction), Ubuntu installer for desktop only can use ZFS as root file-system but is **still experimental** and provides only a mono-disk installation. Please give us details on the installation method you used if you expect help.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
