Thanks Everyone..
So it seems like the cephadm activate is a development branch capability currently.. And the workaround is to activate all as legacy daemons, then adopt as containers.
Appreciate the inputs. Will try it out.

Hi,
The osd activate will probably be nice in the future, but for now I'm doing it like this:
ceph-volume activate --all
for id in `ls -1 /var/lib/ceph/osd`; do echo cephadm adopt --style legacy --name ${id/ceph-/osd.}; done
It's not ideal because you still need the ceph rpms installed and start each osd twice, but it's the only way I found to do this semi-automatically

Hi,
Assuming you are using cephadm? Checkout this https://docs.ceph.com/en/latest/cephadm/osd/#activate-existing-osds
ceph cephadm osd activate <host>...
Might not be backported.
see https://tracker.ceph.com/issues/46691#note-1 for the workaround

Hello,
TL;DR
Looking for guidance on ceph-volume lvm activate --all as it would apply to
a containerized ceph deployment (Nautilus or Octopus).
Detail:
I’m planning to upgrade my Nautilus non-container cluster to Octopus
(eventually containerized). There’s an expanded procedure that was tested
and working in our lab, however won’t go into the whole process. My
question is around existing OSD hosts.
I have to re-platform the host OS, and one of the ways in the OSDs were
reactivated previously when this was done (non-containerized) was to
install ceph packages, deploy keys, config, etc. then run ceph-volume lvm
activate --all to magically bring up all OSDs.
Looking for a similar approach except if the OSDs are containerized, and I
re-platform the host OS (Centos -> Ubuntu), how could I reactivate all OSDs
as containers and avoid rebuilding data on the OSDs?
Thank you.
