Chapter 4. Deploy the Shared File System Service with a CephFS Back End

Once you create /home/stack/templates/manila-cephfsnative-config.yaml, log in as the stack user on the undercloud. Then, deploy the Shared File System service with a CephFS back end by including the following environment files:

  • /usr/share/openstack-tripleo-heat-templates/environments/services/ceph-mds.yaml - enables the Ceph MDS, which is required by Shared File System service when using a CephFS back end.
  • /usr/share/openstack-tripleo-heat-templates/environments/manila-cephfsnative-config.yaml - deploys the Ceph cluster.
  • /home/stack/templates/manila-cephfsnative-config.yaml - created earlier in Chapter 3, Edit the Environment File, and contains any settings to override defaults set in /usr/share/openstack-tripleo-heat-templates/environments/manila-cephfsnative-config.yaml.

For example, if your OpenStack and Ceph settings are defined in /home/stack/templates/storage-environment.yaml, run:

$ openstack overcloud deploy --templates \
   -e /home/stack/templates/storage-environment.yaml \
   -e /usr/share/openstack-tripleo-heat-templates/environments/manila-cephfsnative-config.yaml \
   -e /usr/share/openstack-tripleo-heat-templates/environments/services/ceph-mds.yaml \
   -e /home/stack/templates/manila-cephfsnative-config.yaml \
Important

If you passed any extra environment files when you created the overcloud, pass them again here using the -e option to avoid making undesired changes to the overcloud. For more information, see Modifying the Overcloud Environment in the Director Installation and Usage guide.

Test the back end after director orchestration is complete.
