How to enumerate local windows volumes, excluding cluster volumes using Powershell?

I have tried get-volume, wmi/cim etc, but every example I've tried lists all volumes. What I need is a list of only the local volumes, not any cluster volumes.

Solved - code below: $myDisks = Get-CimInstance -ClassName Win32_LogicalDisk | Where-Object –FilterScript {$.DriveType -Eq 3} | Select-Object DeviceID, VolumeName, Size, FreeSpace, @{Name="UsedSpace"; Expression={$.Size - $_.FreeSpace}} | Sort-Object -Property DeviceID $myServer = (Get-Content env:COMPUTERNAME).ToUpper() Import-Module FailoverClusters $myCluster = $(Get-Cluster).Name $myClusterDisks = Get-CimInstance -Namespace Root\MSCluster -ClassName MSCluster_Resource -ComputerName $myCluster | Where-Object –FilterScript {($.Type -eq 'Physical Disk') -and ($.OwnerNode -eq $myServer)} $myClusterVolumes = $myClusterDisks | %{Get-CimAssociatedInstance -InputObject $_ -ResultClassName MSCluster_DiskPartition} | Select-Object Path, VolumeLabel, TotalSize, FreeSpace, @{Name="UsedSpace"; Expression={$.TotalSize - $.FreeSpace}} | Sort-Object Path $myLocalVolumes = $myDisks | Where {$_.DeviceId -notin @($myClusterVolumes.Path)}

Welcome to SO. Can you exclude cluster shared volume file systems (CSVFS)? For example, Get-Volume | where {$_.FileSystem -ne 'CSVFS'} | ft or perhaps Get-Volume | where {$_.FileSystem -in @('NTFS','FAT32','ReFS')} | ft – leeharvey1
Hmmm, not sure what "CSVFS" is, all the cluster vols are NTFS or ReFS. – SSchaub
Lee, you put me on the right track with your "where -in" clause. I basically had to get all disks, then get only cluster disks, then pull all disks that were -notin the cluster disks. Not as straight-forward as I would have hoped from Powershell, but it gets the job done. Thanks. – SSchaub

In some cases, local disks have a Disk Number, non-local ones do not. Therefore, to get the volumes for only the disks which exist on the local cluster, exclude the disks where the DiskNumber returned by Get-Partitions is null. In other cases, the 'AccessPaths' for the cluster volumes are null, so you can exclude the partitions with a filter on that. Then you can get the volumes matching those partitions.

$parts = Get-Partition | Where-Object -Property 'DiskNumber' -ne $null
$parts | Format-Table -AutoSize -Property 'OperationalStatus', 'Type', 'DiskNumber', 'DriveLetter', 'IsActive', 'IsBoot', 'IsHidden', 'IsOffline', 'IsShadowCopy', 'IsSystem', 'MbrType', 'NoDefaultDriveLetter', 'Offset', 'PartitionNumber', 'Size', 'TransistionState', 'AccessPaths'
$vols = Get-Volume -Path ( $parts.AccessPaths -match '^\\\\\?\\Volume{' )
$vols | Format-Table -AutoSize -Property 'OperationalStatus', 'HealthStatus', 'DriveType', 'FileSystemType', 'FileSystemLabel', 'AllocationUnitSize', 'DriveLetter', 'Size', 'SizeRemaining'

To return only volumes with drive letters, add this to the end of the first line above:

 | Where-Object -Property 'DriveLetter' -ne 0x00
