When ready to apply the changes, it may be advisable to do so in batches, or at
least start with a small number of hosts.:
least start with a small number of hosts:

.. code-block:: console

kayobe overcloud host configure --limit <host>

Alternatively, to apply the configuration to all hosts:

.. code-block:: console
.. warning::

Take extra care when configuring Ceph hosts. Set the hosts to maintenance
mode before reconfiguring them, and unset when done:

.. code-block:: console

kayobe playbook run $KAYOBE_CONFIG_PATH/ansible/ceph-enter-maintenance.yml --limit <host>
kayobe overcloud host configure --limit <host>
kayobe playbook run $KAYOBE_CONFIG_PATH/ansible/ceph-exit-maintenance.yml --limit <host>

kayobe overcloud host configure
**Always** reconfigure hosts in small batches or one-by-one. Check the Ceph
state after each host configuration. Ensure all warnings and errors are
resolved before moving on.
