Hello,
I am new to CEPH and on a few test servers attempting to setup and
learn a test ceph system.
I started off the install with the "Cephadm" option and it uses podman
containers.
Followed steps here:
https://docs.ceph.com/docs/master/cephadm/install/
I ran the bootstrap, added remote hosts, added monitors and everything
is looking good.
Now I would like to add OSDs...
On the bootstrapped server i did a :
ceph-volume lvm prepare --data /dev/sda6
and then the "activate" and "ceph orch daemon add osd (etc)" to
add
it and it works...
But now I am ready to add OSDs on the remote nodes. I am not able to
find documentation or examples on how to do :
ceph-volume lvm prepare & activate steps on the remote hosts.
How do we prepare & activate the remote hosts disks?
Thank you very much for your input,
Cheers
Steve

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
?
Thank you very much for your input,
Cheers

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
