The above is normal. Looks like you're using it as expected.

I assume that ${_THT} refers to
/usr/share/openstack-tripleo-heat-templates. I don't recommend editing
the THT shipped with TripleO. If it has been modified then I recommend
restoring it to the original from the RPM.

Those roles will be used if you're also trying to configure manila:

 https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/features/deploy_manila.html#deploying-the-overcloud-with-the-internal-ceph-backend

It will get the OSD running first however and that's failing the the
vdb issue in your log below ([1]).
