I am not really sure which file the ceph-deploy is complaining about: Its certainly not the ~/.cephdeploy.conf or ceph.conf. I am also able use debugger as running under debugger looses info about the config file location.

Answer 1

The deployment tool ceph-deploy has been deprecated in favor if cephadm a couple of releases ago. Although this doesn't really answer your question it's gonna be difficult to keep ceph-deploy functional with newer releases. I recommend to switch to cephadm.
