@zak1 -

 

TLDR:  Double check variables and spelling as there are lots of things undefined (but that isn't always bad). The other thing that might be wrong is towards the end, it mentions /dev/vdb has existing formatting and volumes (indicates previous things might not be cleaned up). I would suggest running using parted/fdisk or something to wipe the VDB disk and running the playbook again. If that doesn't work, look at the items below.

 

ansible-lint and the ansible --syntax-check only look for formatting issues and large issues. Just because it passes doesn't mean you have a good playbook. In your case, you were to create a playbook using the storage role. Since you are using a role, and not modules, you need to account for that as the roles take variables so I believe you are missing the entire "VARS" section. You provided the "ROLE NAME" like you would an ansible module, but when using the "ROLE" you need all the vars required so you can pass the variables to the role. I am not looking at the course content, just your playbook and the error. I've also provided a blog post that can help. I haven't found your exact error, but I suspect you are missing a variable that is needed.

The Blog post does things slightly different as you can specify the "VARS" at a play level or a role level. My suggested fix is the role level, but it is up to you how you want to do it. The important thing is that the ROLE sees the variables so it can use them. Right now, you are getting errors because nothing is defined for the ROLE.

the supported ones are these :

However, let me also inform you that I was unable to reproduce this issue in my lab :

As this is a comp -review lab, I strongly recommend you to delete your existing lab and recreate a fresh one. Then you can retry this one more time.

@zak1 you are again back to the same error that you posted in the original post.

Please follow what I recommend :

1. go to your lab env - click on "Delete".

2. Once your labs are deleted, click on "Create".

3. When your lab VMs are active - please proceed with the lab exercise from lab start script.

4. You dont need to touch any of the role tasks, you have to "Write a playbook named storage.yml that uses the redhat.rhel_system_roles.storage system role to configure logical volumes for the managed hosts in the webservers group specified by the inventory file in your project directory".
