Limitations of NTFS volume mountpoints

Volume mountpoints in an NTFS environment, or on a server cluster have limitations with their creation, the supported clustered configuration, and placement with respect to the Quorum disk.

The NTFS volume mountpoints feature imposes the following limitations:

You can create volume mountpoints only on a dedicated disk or a shared cluster resource disk.
You cannot use volume mountpoints as storage locations for the Exchange Server 2003 binaries.
You cannot use volume mountpoints on a server cluster.
You cannot place volume mountpoints between clustered and nonclustered disks.
You cannot create mountpoints that refer to the Quorum disk.

Using server cluster mountpoints includes the following limitations:

The mounted volume must be of the same type as its root; that is, if the root volume is a shared cluster resource, the mounted volume must also be shared, and if the root volume is dedicated, the mounted volume must also be dedicated.
You cannot create mountpoints to the Quorum disk.
If you have a mountpoint from one shared cluster resource disk to another, ensure that the disks are in the same group and that the mounted disk resource is dependent on the root disk source.
