6.8. 原生 CephFS 后端环境文件

用于定义原生 CephFS 后端 manila-cephfsnative-config.yaml 的环境文件位于 undercloud 节点的以下路径中： /usr/share/openstack-tripleo-heat-templates/environments/manila-cephfsnative-config.yaml。

manila-cephfsnative-config.yaml 环境文件包含与部署共享文件系统服务相关的设置。后端默认设置应该适用于大多数环境。

示例显示了 director 在部署共享文件系统服务过程中使用的默认值：

[stack@undercloud ~]$ cat /usr/share/openstack-tripleo-heat-templates/environments/manila-cephfsnative-config.yaml

# A Heat environment file which can be used to enable a
# a Manila CephFS Native driver backend.
resource_registry:
  OS::TripleO::Services::ManilaApi: ../deployment/manila/manila-api-container-puppet.yaml
  OS::TripleO::Services::ManilaScheduler: ../deployment/manila/manila-scheduler-container-puppet.yaml
  # Only manila-share is pacemaker managed:
  OS::TripleO::Services::ManilaShare: ../deployment/manila/manila-share-pacemaker-puppet.yaml
  OS::TripleO::Services::ManilaBackendCephFs: ../deployment/manila/manila-backend-cephfs.yaml

parameter_defaults:
  ManilaCephFSBackendName: cephfs 1
  ManilaCephFSDriverHandlesShareServers: false 2
  ManilaCephFSCephFSAuthId: 'manila' 3
  ManilaCephFSCephFSEnableSnapshots: true 4
  ManilaCephFSCephVolumeMode: '0755'  5
  # manila cephfs driver supports either native cephfs backend - 'CEPHFS'
  # (users mount shares directly from ceph cluster), or nfs-ganesha backend -
  # 'NFS' (users mount shares through nfs-ganesha server)
  ManilaCephFSCephFSProtocolHelperType: 'CEPHFS'  6

parameter_defaults 标头表示配置的开头。具体来说，此标头中的设置可让您覆盖 resource_registry 中设置的默认值。这包括 OS::Tripleo::Services::Services::ManilaBackendCephFs 设置的值，它为 CephFS 后端设置默认值。
