Step 1 Find out which volume is the CSV

Open up a Windows PowerShell session.
Run "List Volume" | diskpart.

Note down the CSVFS Volume path. In the example below, the path is "C:\ClusterStorage\Volume1\".

Note:

If you have multiple Clustered Shared Volumes across a large number of Windows Server Failover Clusters, the following PowerShell can be used to determine the CSVs on each of the individual clusters from one centralized PowerShell script.


Import-Module FailoverClusters
$Volumes = @()
$ClusterName = "<CLUSTER_NAME>"

$CSV = Get-ClusterSharedVolume -Cluster $ClusterName
ForEach ($CSV in $CSVS) {
  $CSVInfo = $CSV | Select -Property Name -ExpandProperty SharedVolumeInfo
  ForEach ( $CSVInfo in $CSVInfos ) {
    $Volumes = New-Object PSObject -Property @{
       Path = $CSVInfo.FriendlyVolumeName
    }
    $Volumes.Path
  }
}
