How to add storage to Clustered Shared Volumes in Windows Server 2012

First published on MSDN on Apr 06, 2012

In  2012 Cluster Shared Volumes (CSV) has been more tightly integrated into the Clustering feature. The process for a cluster Physical Disk Resource (PDR) to be enabled for CSV has been simplified and streamlined. In this blog, I will show you the new experience of adding from the


pool of your cluster to Clustered Shared Volumes. The


pool contains disks that have been added to your cluster but not assigned to a specific use in your cluster.

Cluster Manager

To add storage to Clustered Shared Volumes follow these steps:

1)      Launch the

Cluster Manager


2)      Select the



3)      Select the Disks that you want to add to Clustered Shared Volumes.

Note:  A great new Failover Cluster Manager feature in  2012 is support for multi-select and the ability to enable CSV across a number of disks all at once!

4)      Right click on your selection and choose the

Add to Cluster Shared Volumes


5)      Your disks are now added to Clustered Shared Volumes! Yes, it is that easy in 2012!

CSV provides a single consistent file name space. Files have the same name and path when viewed from any node in the cluster. CSV volumes are exposed as directories and subdirectories under the “


” root directory:

CSV enabled volumes now appear as “CSVFS”. CSVFS is the NTFS file system under the covers and volumes are still formatted with the NTFS file system. However, this change enables applications to be aware that they are running on CSV and allows them to ensure compatibility.


You can also use the Failover Clustering Windows PowerShell® cmdlet,


, to add storage to Clustered Shared Volumes. This cmdlet accepts disks from the

Available Storage


Note:  Another awesome Windows Server 2012 Failover Clustering PowerShell® feature is the support for Wildcard characters! The screenshot above shows you an example of how you can use wildcards to select multiple PDRs to add to CSV at once.
