It turned out to be a missing systemd unit file.  I would suggest that you check to see that you have an instance of ceph-volume@.service and an instance of ceph-osd@.service running for each OSD.

> In my case I found that the proto-unit for one of these (ceph-volume@.service, I think) was missing from /var/lib/systemd/system.   In fact, it was missing from the Debian install package for some reason.  I think I had to unpack a copy of the Debian SRC pacakge to retrieve the file.  Once I added the missing file and made sure the unit was enabled, things started working better and making more sense.  I don't recall if all of the instances created themselves or whether I had to do something addtional, but it worked.


Hi Dave,

I'm looking around but can't identify any missing file.

ceph-osd@.service and ceph-volume@.service are present. I'm looking on
the other servers for some other file that might be missing but can't
find anything.

Thanks for your help,

Rodrigo
