Ok, I'm not sure if I'm missing something or if this is a gap in ceph orch 
functionality, or what:

On a given host all the OSDs share a single large NVMe drive for DB/WAL storage 
and were set up using a simple ceph orch spec file.  I'm replacing some of the 
OSDs.  After they've been removed with the dashboard equivalent of "ceph orch 
osd rm # --replace" and a new drive has been swapped in, how do I get the OSD 
recreated using the chunk of NVMe for DB/WAL storage?  Because the NVMe has 
data and is still in use by other OSDs, the orchestrator doesn't seem to 
recognize it as a valid storage location, so it won't create the OSDs when I do 
"ceph orch apply -i osdspec.yml".

Thoughts?
