openshift_env facts overwrite top level keys; a fix is present here: https://github.com/openshift/openshift-ansible/pull/6272
We need an rpm created that includes this fix as it's currently being patched manually.
https://github.com/openshift/openshift-ansible/pull/6293 fix already backported
The patch was merged into openshift-ansible-3.7.14-1.git.0.4b35b2d.el7.noarch. And no such error when trying ocp-3.7 installation with metrics enabled with external nfs.
With the following options added in ansible inventory file, start running playbooks/byo/config.yml
Installation is successful and pv for metrics is created correctly.
