Adding OSD nodes to the Ceph configuration file

Now, let's add the OSD nodes details to the /etc/ceph/ceph.conf file from ceph-node1 using Ansible:

1. On ceph-node1 in the /usr/share/ceph-ansible/group_vars directory, edit the ceph_conf_overrides section of the all.yml to reflect the OSD nodes details. As with the monitors, please be careful with the formatting of the file or the running of the playbook will fail with a formatting error:

# ansible-playbook site.yml
