Description:

Cluster Shared Volumes (CSV) are shared drives holding an NTFS volume that can be written to by all cluster nodes in a Windows Server Failover Cluster.

They are especially important for Microsoft Hyper-V virtualization, because all host servers can see the same volume and can store multiple Virtual Machines on that volume. Using CSVs will allow Windows to perform Live Migration with less timeouts.

Unfortunately, many third party applications do not support CSVs. In addition, CSVs can be much harder to troubleshoot.

Instructions:

If you need to disable CSVs, use the following command in PowerShell:

Get-Cluster | %{$_.EnableSharedVolumes = “Disabled”}
