Hey Jonathan,
Thanks for this.
I've figured it out using the previous examples and some more googleing :)
I got it to execute a shell command which i what I needed it to do:
- shell: pvcreate /dev/"{{ item.key }}"
with_dict: ansible_devices
when: not item.value.partitions and item.key != "sr0" and item.key !=
"fd0"
Thanks again
