aws-cloudformation - 创建卷 DeleteOnTermination=true 的实例失败

Question

我有如下所示的云形成模板。这里我想让卷全部DeleteOnTermination为true。为了实现这一点，我添加了 BlockDeviceMappings 部分，仅允许为 DeleteOnTermination 设置值。但我收到错误: unixDevice 的值“/dev/sdf”无效。连接点/dev/sdf 已在使用

我做错了什么？我应该从卷部分删除/dev/sdf 并将其仅保留在 BlockDeviceMappings 中吗？

在模板中仅保留一个/dev/sdf。 “AWS::EC2::Volume”或来自 BlockDeviceMappings 或更改一个驱动器的名称。您不能保留两个同名的卷。
