我的 Windows 2008R2 服务器报告以下错误:
磁盘上的文件系统结构已损坏且无法使用。请在卷\Device\HarddiskVolume2上运行 chkdsk 实用程序。
使用 Powershell 和 WMI 在查询时如何识别这是哪个卷Win32_Volume。
例如,如果我这样做:
Get-WmiObject Win32_Volume

我得到了服务器上所有卷的列表,但是没有一个Win32_Volume类属性使用(看起来是)这个“友好”名称 - \Device\HarddiskVolume2。我可以看到有一个DeviceID属性返回如下值:
DeviceID : \\?\Volume{4bc3df2a-65c7-11e0-9c33-806e6f6e6963}\

还有一个Name属性,但这只是分配给卷的驱动器号。其他属性的值都与事件日志中报告的值相差甚远。
fltmc volumes我知道我可以解析或 的输出来DISKPART获取此信息,但必须有一种方法可以在 PowerShell 脚本中使用 WMI 来获取此信息。
我还查看了Win32_DiskDrive,Win32_DiskPartition和Win32_LogicalDisk类,但没有提到类似的属性值\Device\HarddiskVolume2。

看看这段代码:http://poshcode.org/4768它似乎做了你需要的转换,看看你想要什么,你也许可以调整它以满足你的需要,如果你需要帮助,请告诉我但我认为你可以自己弄清楚。
function Get-DevicePath
{
<#
.SYNOPSIS
Returns the device paths for each volume.

.DESCRIPTION
Get-DevicePath returns the corresponding device path for each drive letter. This is useful for converting device paths to drive letters.
.EXAMPLE
Get-DevicePath
DevicePath DriveLetter
---------- -----------
\Device\HarddiskVolume2 D:
\Device\HarddiskVolume4 C:
.OUTPUTS
PSObject[]
For each mount point, a PSObject is returned representing the drive letter and device path.
