linux - aws 在 hvm 虚拟化中使用 Chef 附加 ebs 卷

Question

我有一个 Chef 配方，它尝试创建并附加 EBS 卷，但始终失败。它在我之前使用的所有半虚拟化类型的 AMI 上都运行良好。但是，当我尝试切换并使用 hvm 虚拟化时，它失败并告诉我挂载点已在使用中。但似乎并非如此。

我创建/附加卷的方法是从该资源中紧密复制的，作者在其中创建了单个 EBS 卷。 http://clarkdave.net/2013/04/managing-ebs-volumes-with-chef/#creating-the-ebs-volumes

@adam_Ocsvari 的方法是正确的。当我将设备从安装 /dev/sdb 切换到 /dev/sdf 时，一切立即正常工作。
