No Ceph configured so none of the steps works.
Thank you for letting us know. The ceph and python have had many changes recently. I am in the process of updating all the labs and hope to roll out the fixes soon. As well move to a more stable environment, so these issues are minimized. Once the new process is finished the automation scripts will be created and the lab will again work.
I appreciate your patience, please give us a little more time.
