红帽全球峰会第 4 章 使用 CephFS 后端部署共享文件系统服务
创建 /home/stack/templates/manila-cephfsnative-config.yaml 后，以 stack 用户身份登录 undercloud。然后，通过包含以下环境文件，使用 CephFS 后端部署共享文件系统服务：
-
/usr/share/openstack-tripleo-heat-templates/environments/services/ceph-mds.yaml- 启用 Ceph MDS，在使用 CephFS 后端时共享文件系统服务是必需的。 -
/usr/share/openstack-tripleo-heat-templates/environments/manila-cephfsnative-config.yaml- 部署 Ceph 集群。 -
/home/stack/templates/manila-cephfsnative-config.yaml- 前面创建，并包含任何在/usr/share/openstack-tripleo-heat-templates/environments/manila-cephfsnative-config.yaml中设置的默认值。第 3 章 编辑环境文件
例如，如果您的 OpenStack 和 Ceph 设置在 /home/stack/templates/storage-environment.yaml 中定义，请运行：
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 \
$ 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 \重要
如果您在创建 overcloud 时传递任何额外的环境文件，请使用 -e 选项再次传递它们，以避免对 overcloud 进行不必要的更改。有关更多信息，请参阅 Director 安装和使用 指南中的 修改 Overcloud 环境。
