如何为我的gp2 EC2实例配置EC2引导卷？

Question

我想使用新的"gp2“卷类型作为我的.NET实例的启动卷，其中包括来自亚马逊的开箱即用的Windows (例如ami-527b823a)，以及用于.NET的AWS (v2.1.7 -最近的版本为2014年7月9日)。如何配置运行实例请求？

基于AWS博客上的文章，我尝试设置一个BlockDeviceMapping：

new RunInstancesRequest {
    ...
    BlockDeviceMappings = {
        BlockDeviceMapping {
            DeviceName = "sda1",
            Ebs = new EbsBlockDevice { VolumeType = VolumeType.Gp2 }
        },
        new BlockDeviceMapping {
            DeviceName = "xvdf",
            Ebs = new EbsBlockDevice {
                SnapshotId = SNAPSHOT_ID
                DeleteOnTermination = true,
                VolumeType = VolumeType.Gp2
            }
        }
        ...
    }
}

但这不管用，我有一个不令人意外的例外：

Amazon.EC2.AmazonEC2Exception: The device 'sda1' is used in more than one
block-device mapping ---> System.Net.WebException: The remote server
returned an error: (400) Bad Request.
   at System.Net.HttpWebRequest.GetResponse()
   ...

是否可以将windows实例的引导(根)卷设置为gp2？还是我需要等待稍后发布的SDK？

使用用于.NET的AWS的以下代码和2.1.7版本，我能够成功地使用GP2 EBS根卷启动：

BlockDeviceMapping mapping = new BlockDeviceMapping
{
    DeviceName = "/dev/sda1",
    Ebs = new EbsBlockDevice
    {
        VolumeType = VolumeType.Gp2,
        VolumeSize = 30
    }
};
var request = new RunInstancesRequest
{
    BlockDeviceMappings = { mapping },
    ImageId = "ami-527b823a",
    InstanceType = InstanceType.M1Small,
    MinCount = 1,
    MaxCount =1
};
var ec2Client = new AmazonEC2Client(RegionEndpoint.USEast1);
ec2Client.RunInstances(request);
