8.5. 配置多个后端

流程

1. 打开 OpenStackControlPlane CR 文件 openstack_control_plane.yaml，并在 manila 模板中添加以下参数来配置后端。在本例中，有 CephFS-NFS 后端、原生 CephFS 后端和 Pure 存储后端：

   apiVersion: core.openstack.org/v1beta1
   kind: OpenStackControlPlane
   spec:
       ...
     manila:
       enabled: true
       template:
         manilaAPI:
           replicas: 3
           customServiceConfig: |
             [DEFAULT]
             debug = true
             enabled_share_protocols=nfs,cephfs,cifs
         manilaScheduler:
           replicas: 3
       ...

2. 为每个要使用的后端添加配置：

   • 为 CephFS-NFS 后端添加配置：

         ...
             customServiceConfig: |
             ...
             manilaShares:
               cephfsnfs:
                 networkAttachments:
                 - storage
                 customServiceConfig: |
                     [DEFAULT]
                     enabled_share_backends=cephfsnfs
                     [cephfsnfs]
                     driver_handles_share_servers=False
                     share_backend_name=cephfs
                     share_driver=manila.share.drivers.cephfs.driver.CephFSDriver
                     cephfs_auth_id=openstack
                     cephfs_cluster_name=ceph
                     cephfs_nfs_cluster_id=cephfs
                     cephfs_protocol_helper_type=NFS
                 replicas: 1
         ...

   • 为原生 CephFS 后端添加配置：

         ...
             customServiceConfig: |
             ...
             manilaShares:
               cephfsnfs:
               ...
               cephfs:
                 networkAttachments:
                 - storage
                 customServiceConfig: |
                   [DEFAULT]
                   enabled_share_backends=cephfs
                   [cephfs]
                   driver_handles_share_servers=False
                   share_backend_name=cephfs
                   share_driver=manila.share.drivers.cephfs.driver.CephFSDriver
                   cephfs_conf_path=/etc/ceph/ceph.conf
                   cephfs_auth_id=openstack
                   cephfs_protocol_helper_type=CEPHFS
                 replicas: 1
         ...

   • 为 Pure 存储后端添加配置：

         ...
             customContainerImages:
               manilaShareImages:
                 pure: registry.connect.redhat.com/purestorage/openstack-manila-share-pure:rhoso18
             manilaShares:
               cephfsnfs:
               ...
               cephfs:
               ...
               pure:
                 networkAttachments:
                 - storage
                 customServiceConfigSecret: |
                 - manila-pure-secret
                 customServiceConfig: |
                   [DEFAULT]
                   debug = true
                   enabled_share_backends=pure
                   [pure]
                   driver_handles_share_servers=False
                   share_backend_name=pure
                   share_driver=manila.share.drivers.purestorage.flashblade.FlashBladeShareDriver
         ...

3. 更新 control plane：

   $ oc apply -f openstack_control_plane.yaml -n openstack

4. 等待 RHOCP 创建与 OpenStackControlPlane CR 相关的资源。运行以下命令来检查状态：

   $ oc get openstackcontrolplane -n openstack

   Copy to Clipboard Toggle word wrap

   当状态为 "Setup complete" 时，会创建 OpenStackControlPlane 资源。

   提示

   将 -w 选项附加到 get 命令的末尾，以跟踪部署进度。
