Ceph » Orchestrator

This configuration mechanism doesn't seem to work with config parameters like mgr/cephadm/device_enhanced_scan - I guess it might only work with parameters missing the service/something/ part, such as the example mds_cache_memory_limit?

It would be nice and save head-scratching & useless attempts if this was actually documented. The documentation at https://docs.ceph.com/en/quincy/cephadm/services/#service-specification makes it seem like there are no restrictions. But unless I am doing something wrong on 17.2.6 I could not set on the MGR service spec:

config:
  mgr/cephadm/device_enhanced_scan: true

Additionally, this fails at ceph orch apply stage and it does not raise health warnings as documented.

It is as if these service/something/param parameters are completely forgotten by this feature and the documentation - or I am doing something wrong which wouldn't be the first time.

Of course it would be even better if these parameters could be set in service specification (along with config-key parameters!)

I guess I should open a new issue for this but I'm afraid it's just me doing it wrong again...
