On Debian I have had the experience that one of the OSD-related systemd
unit files was not installed - sorry that I can't recall which one, but
the error you describe is the same one I had.
The required file was in the source package, but was apparently left off
the list of files to be copied into the install package. Once I copied
the file over to /lib/systemd/system everything started working again.
If I had to guess it was either ceph-volume@.service, or more likely -
based on timestamps on my one of my OSD servers, ceph-osd@.service.
Hope this helps.
