3.6. 准备只导入的迁移

流程

1. 创建 JSON 文件：

   示例

   [ceph: root@rbd-client /]# cat testspec.json
    {
      "type": "raw",
       "stream": {
           "type": "s3",
           "url": "http:10.74.253.18:80/testbucket1/image.raw",
          "access_key": "RLJOCP6345BGB38YQXI5",
          "secret_key": "oahWRB2ote2rnLy4dojYjDrsvaBADriDDgtSfk6o"
     }

2. 准备仅导入实时迁移过程：

   语法

   rbd migration prepare --import-only --source-spec-path "JSON_FILE" TARGET_POOL_NAME

   示例

   [ceph: root@rbd-client /]# rbd migration prepare --import-only --source-spec-path "testspec.json" targetpool1

   注意

   rbd migration prepare 命令接受与 rbd create 命令相同的所有镜像选项。

3. 您可以检查仅导入实时迁移的状态：

   示例

   [ceph: root@rbd-client /]# rbd status targetpool1/sourceimage1
   Watchers: none
   Migration:
   source: {"stream":{"access_key":"RLJOCP6345BGB38YQXI5","secret_key":"oahWRB2ote2rnLy4dojYjDrsvaBADriDDgtSfk6o","type":"s3","url":"http://10.74.253.18:80/testbucket1/image.raw"},"type":"raw"}
   destination: targetpool1/sourceimage1 (b13865345e66)
   state: prepared
