无法检索群集可用存储的物理大小 [英] Unable to retrieve physical size of available storage for cluster

问题描述

我的工作已经进行到一半，现在卡住了。

I am half way down with my work and now stuck.

我正在尝试获取有关群集的可用存储设备的信息。
我能够获取可用存储设备的列表，但无法检索这些可用存储的物理磁盘，可用空间等。

I am trying to fetch information about available storage devices for a cluster. I am able to fetch the list of available storage devices but unable to retrieve the physical disk, available free space, etc of these available storage.

我想要像这样。是否有任何命令可以从群集磁盘名称中获取物理磁盘名称，或者可以直接获取磁盘详细信息。
对于共享磁盘，我可以检索详细信息（ Get-ClusterSharedVolume ），但不适用于非共享磁盘。
我想要执行powershell或WMI脚本。

I want like this. Is there any command to fetch physical disk name from Cluster Disk Name or directly can I get the disk details. For Shared Disk I am able to retrieve the details (Get-ClusterSharedVolume) but not for a non-shared disk. I want powershell or WMI script for doing so.

推荐答案

您可以从WMI获取此信息，但需要执行以下几个步骤：

You can get this information from WMI, but it takes a couple steps:

$resources = Get-WmiObject -namespace root\MSCluster MSCluster_Resource -filter "Type='Physical Disk'"
$resources | foreach {
    $res = $_
    $disks = $res.GetRelated("MSCluster_Disk")
    $disks | foreach {
        $_.GetRelated("MSCluster_DiskPartition") |
            select @{N="Name"; E={$res.Name}}, @{N="Status"; E={$res.State}}, Path, VolumeLabel, TotalSize, FreeSpace 
    }
} | ft

这将为您提供如下输出：

That will give you output like the following:

Name                  Status Path  VolumeLabel  TotalSize  FreeSpace
----                  ------ ----  -----------  ---------  ---------
Cluster Disk 2             2 K:    New Volume        5220       5163
SQL - FAS3070 SiteB        2 S:    MC_SQL            5597       5455
SM Test                    2 M:    SM Test           1024        992
DTC - FAS3070B             2 F:    MC_WITNESS        5346       5289
Cluster Disk Witness       2 E:    New Volume        5322       5267
Cluster Disk 1             2 G:    MC_DTC            5088       5035
Cluster Disk 3             2 T:    SQL               5119       4999

如果您不关心资源名称/状态，您可以跳过这些步骤而直接跳到分区（它将运行得更快）：

If you don't care about the resource name/status you can skip those steps and jump straight to the partition (and it'll run much quicker):

gwmi -namespace root\MSCluster MSCluster_DiskPartition | ft Path, VolumeLabel, TotalSize, FreeSpace

编辑：请注意，大小以MB为单位，状态为 2表示磁盘处于联机状态。

Note that the size is in MB and a Status of "2" means that the disk is online.
