Upgrading the ceph cluster
-------------------
ceph-ansible provides a playbook in ``infrastructure-playbooks`` for upgrading a Ceph cluster: ``rolling_update.yml``.
This playbook could be used for both minor upgrade (X.Y to X.Z) or major upgrade (X to Y).
Before running a major upgrade you need to update the ceph-ansible version first.
example:
.. code-block:: shell
$ ansible-playbook -vv -i hosts infrastructure-playbooks/rolling_update.yml
.. note::
This playbook isn't intended to be run with the ``--limit`` ansible option.
