~Has anyone successfully wired up an external ceph cluster to harvester before? https://harvesterhci.io/kb/use_rook_ceph_external_storage/ and https://www.rook.io/docs/rook/latest-release/CRDs/Cluster/external-cluster/external-cluster/?h=external+cluster~ 1. Where do you run the create-external-cluster-resources.py script exactly? 2. Where is the python rados module found?
