Actually, what confused me was this:
cephadm bootstrap --mon-ip <my-ip>
Among other things, this command:
- Generates a new SSH key for the Ceph cluster and adds it
to the /root/.ssh/authorized_keys file.
- Saves a copy of the public key to the /etc/ceph/ceph.pub file.
You then need to add a node.
ssh-copy-id -f -i /etc/ceph/ceph.pub root@<new-host>
ceph orch host add <newhost> [<ip>] [<label1> ...]
I wondered where the private part of the SSH key /etc/ceph/ceph.pub was !
