Hi Dan,

I opened a tracker: https://tracker.ceph.com/issues/57348

Exactly, this is also what the documentation says.

I included this as a bug as well. Crush should never return a mapping containing an OSD that is not up+in. There is probably a test missing somewhere in the recursion.

Thanks for your help and best regards,
