You create volumes and attach them to instances to provide persistent storage.

前提条件

  • If you want to create a volume from an image, upload the desired image. See 导入映像.
  • If you want to create an FCD-backed volume, verify that you have added at least one Cinder host using the FCD back end. Then create a volume type and set its vmware:backend_name extra spec to the name of the FCD back end. Select this volume type during the volume creation process. For information about volume types, see 创建卷类型.
