Hello,
If you do it, like Sebastian told you, you would automatically deploy osd's.
For a beginner I would recommend to do it semi-automated, so you know a bit more what's going on.
So first do the "ceph orch device ls" which should print every disk, in all nodes.
Then I recommend to zap devices you want to use first, even if it says you can use them:
ceph orch device zap {node} /dev/sd? --force
And then you can add devices one by one:
ceph orch daemon add osd {node}:/dev/sd?
Just to top it off.
Regards,
Simon

ceph orch apply osd
as described in
https://docs.ceph.com/docs/master/cephadm/install/#deploy-osds
should do the trick. In case it doesn't, what's the output of
ceph orch device ls
?
