在 Azure VM 上访问 DSC 中新连接的磁盘时出现问题

Question

我尝试使用 DSC 配置在 Azure VM 上安装和运行 mongo 服务时遇到问题。

当 DSC 运行初始部署 VM 时，辅助磁盘 'F' 已成功附加并格式化，但是...我在尝试创建目录时收到错误新磁盘：

Error message: \"DSC Configuration 'Main' completed with error(s).
Cannot find drive. A drive with the name 'F' does not exist. 
The PowerShell DSC resource '[Script]SetUpDataDisk' with SourceInfo 'C:\Packages\Plugins\Microsoft.Powershell.DSC\2.73.0.0\DSCWork\MongoDSC.0\MongoDSC.ps1::51::2::Script' threw one or more non-terminating errors while running the Set-TargetResource functionality.

这是我的 DSC 脚本：

Configuration Main
{

Param ( [string] $nodeName )

Import-DscResource -ModuleName PSDesiredStateConfiguration
Import-DscResource -ModuleName xStorage

Node $nodeName
{
    xWaitforDisk Disk2
    {
        DiskId = 2
        RetryIntervalSec = 60
        RetryCount = 60
    }
    xDisk FVolume
    {
        DiskId = 2
        DriveLetter = 'F'
        FSLabel = 'MongoData'
        DependsOn = "[xWaitforDisk]Disk2"
    }
    Script SetUpDataDisk{
        TestScript ={
            return Test-Path "f:\mongoData\"
        }
        SetScript ={
            #set up the directories for mongo

            $retries = 0
            Do{
                $mountedDrive = Get-Volume | Where DriveLetter -eq 'F'
                if($mountedDrive -eq $null)
                {
                    Start-Sleep -Seconds 60
                    $retries = $retries + 1
                }
            }While(($mountedDrive -eq $null) -and ($retries -lt 60))

            $dirName = "mongoData"
            $dbDirName = "db"
            $logDirName = "logs"

            ##! ERROR THROWN FROM THESE LINES
            New-Item -Path "F:$dirName" -ItemType Directory
            New-Item -Path "F:$dirName$dbDirName" -ItemType Directory
            New-Item -Path "F:$dirName$logDirName" -ItemType Directory
        }
        GetScript = {@{Result = "SetUpDataDisk"}}
        DependsOn = "[xDisk]FVolume"
    }
  }
}

烦人的是，如果我运行再次部署，一切正常，没有错误，我已经放入一个循环来尝试等待磁盘准备就绪，但这仍然会引发错误。我是 DSC 的新手，所以任何指示都会有所帮助。

似乎 xDiskAccessPath 可以用于：

<#
    .EXAMPLE
        This configuration will wait for disk 2 to become available, and then make the disk available as
        two new formatted volumes mounted to folders c:\SQLData and c:\SQLLog, with c:\SQLLog using all
        available space after c:\SQLData has been created.
#>
Configuration Example
{

    Import-DSCResource -ModuleName xStorage

    Node localhost
    {
        xWaitforDisk Disk2
        {
             DiskId = 2
             RetryIntervalSec = 60
             RetryCount = 60
        }

        xDiskAccessPath DataVolume
        {
             DiskId = 2
             AccessPath = 'c:\SQLData'
             Size = 10GB
             FSLabel = 'SQLData1'
             DependsOn = '[xWaitForDisk]Disk2'
        }

        xDiskAccessPath LogVolume
        {
             DiskId = 2
             AccessPath = 'c:\SQLLog'
             FSLabel = 'SQLLog1'
             DependsOn = '[xDiskAccessPath]DataVolume'
        }
    }
}
