Unclear how to create dataset

[backupandforkacc]

I am not sure how to use the plugin.

~$ docker volume create testsimon
creates the volume, but no dataset.

The example from github leads to an error:

~$ docker volume create -d zfs -o compression=lz4 -o dedup=on --name=rpool/docker/testsimon
Error response from daemon: create rpool/docker/testsimon: error looking up volume plugin zfs: plugin "zfs" not found

It seems correctly installed:

~$ systemctl list-unit-files --type=service | grep docker-zfs-plugin
docker-zfs-plugin.service                  enabled         enabled

$ ls -lh /usr/local/bin/ | grep zfs
-rw-r--r-- 1 root root 11M Feb  5 09:32 docker-zfs-plugin

I first created the dataset rpool/docker/testsimon, so this is there. Also downloaded the plugin again and put it in /usr/local/bin/, but still get the error.

When I have a look at the status of the service, it says:

$ systemctl status docker-zfs-plugin.service
○ docker-zfs-plugin.service - zfs plugin
