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/ceph-ansible/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/ceph-ansible/ceph-mds.yaml \ -e /home/stack/templates/manila-cephfsnative-config.yaml \
$ 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/ceph-ansible/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.
