Amazon web services 如何在AWS EC2上的Windows中查找驱动器的EBS卷ID

我们有几个EC2实例，都有几个驱动器。当有多个驱动器同时存在时，在AWS控制台中监视哪个驱动器是正确的驱动器会变得很混乱

命名约定可以在一定程度上帮助实现这一点

但是，是否有办法在EBS磁盘的windows中获取卷id（或某些标识符），以便在AWS控制台中找到该卷？

您可以使用该方法查询连接到给定实例的所有卷。下面是一个例子：

# Specify your instance's ID
$instance = "i-1234abcd"

# Get a collection of all volumes attached to the instance
$volumes = @(get-ec2volume) | ? { $_.Attachments.InstanceId -eq $instance}

# Get a collection of each volume's ID property
$volumeNames = $volumes | % { $_.VolumeId}

这将调用cmdlet，并为连接到运行实例的每个卷返回一个对象。从那里，您可以提取如上所述的卷名

如果您是从EC2实例本身运行此操作，请尝试从EC2 web服务中提取实例ID：

# Get Instance ID from the EC2 metadata web service
$instanceID = (New-Object System.Net.WebClient).DownloadString("http://169.254.169.254/latest/meta-data/instance-id")

我使用下面的脚本。此脚本将迭代所有EBS卷，并根据其磁盘标签向EBS添加标记。 您可以根据需要对其进行修改（如有其他块，请参阅底部）。 您的EC2需要正确的EC2写入IAM角色

Start-Transcript -Path C:\cfn\log\Tag-EBS-Volumes.ps1.txt -Append
        # Create a hash table that maps each device to a SCSI target
        $Map = @{"0" = '/dev/sda1'}
        for($x = 1; $x -le 25; $x++) {$Map.add($x.ToString(), [String]::Format("/dev/xvd{0}",[char](97 + $x)))}
        for($x = 78; $x -le 102; $x++) {$Map.add($x.ToString(), [String]::Format("/dev/xvdc{0}",[char](19 + $x)))}

    Try {
        # Use the metadata service to discover which instance the script is running on
        $InstanceId = (Invoke-WebRequest '169.254.169.254/latest/meta-data/instance-id').Content

        $Region = $AvailabilityZone.Substring(0, $AvailabilityZone.Length -1)

        # Get the list of volumes attached to this instance
        $BlockDeviceMappings = (Get-EC2Instance -Region $Region -Instance $InstanceId).Instances.BlockDeviceMappings
    }
