Galera cluster recovery
-----------------------
When one or all nodes fail within a galera cluster you may need to
re-bootstrap the environment. To make take advantage of the
automation Ansible provides simply execute the ``galera-install.yml``
play using the **galera-bootstrap** to auto recover a node or an
entire environment.
#. Run the following Ansible command to show the failed nodes:
.. code-block:: shell-session
# openstack-ansible galera-install.yml --tags galera-bootstrap
Upon completion of this command the cluster should be back online an in
a functional state.
