Error Starting Origin Node



I wanted to setup a small lab consisting of 1 Master, 1 Node, 1 NFS storage Node for the Registry but got the following error during the ansible playbook run. I am using the openshift-ansible installer (for advanced installation) from https://github.com/openshift/openshift-ansible

1. Ansible Playbook Error

TASK: [openshift_node | Start and enable node] ********************************
failed: [master.maomuffy.lab] => {"failed": true}
msg: Job for origin-node.service failed because the control process exited with error code. See "systemctl status origin-node.service" and "journalctl -xe" for details.

failed: [node1.maomuffy.lab] => {"failed": true}

FATAL: all hosts have already failed -- aborting

What could I have done wrong considering I used the documentation here: https://docs.openshift.org/latest/install_config/install/advanced_install.html#single-master

Kind Regards!
