What are Mount Points: A volume mount point can be placed in any empty folder of the host NTFS volume. The mounting is handled transparently to the user and applications. You can add volumes to systems without adding separate drive letters for each new volume, similar to the way Distributed file system (Dfs) links together remote network shares. Volume mount points are robust against system changes that occur when devices are added or removed from a computer.
Mount points used for: :
If you’re running out of drive letters, one trick is to use a mount point for each logical drive that you are going to bring into Windows; this way, performance can be contained to a logical drive and still conform to your drive letter standards.
There are many scenarios in which you would want a large number of drives, such as multiple databases for Microsoft SQL Server or Exchange Server installations. Exchange databases are notorious for needing their own drives per mailbox store
How to create Mount points in windows Cluster
1.Log on to the local computer by using administrative rights to the cluster node that hosts the mount point and the volume for the mount point.
2.On each node of the cluster, use the Disk Management console to make sure that only one node has each disk in the “online” state. The disks should be online on the same node and on only that node.
3.On the disk that will host the volume for the mount point, follow these steps:
a. In the middle pane of the Disk Management console, right-click the disk item where the disk number is shown, and then click Online if the disk is not already online.
b. Right-click the disk item again, and then click Initialize Disk if the disk is not already initialized.
C. If the disk does not have a volume.
d. Right-click some unallocated space, and then click New Simple Volume.
e. When the New Simple Volume Wizard starts, click Next.
f. Enter the volume size, and then click Next.
g. On the Assign Drive Letter or Path screen, click Mount in the following empty NTFS folder, and then click Browse.
h. Expand X:, where X represents the root drive that hosts the mount point. Select an empty folder or create a new folder, click OK, and then click Next.
i. Format the partition by using the NTFS file system, click Next, and then click Finish.
j. Make sure that the volume does not have a drive letter assigned to it.
k. Right-click the disk, click Change Drive Letter and Paths, and then click Add.
l. Click Mount in the following empty NTFS folder, and then click Browse.
m. Expand the root drive that hosts the volume for the mount point. Select an empty folder, or create a new folder, and then click OK two times.
5.Follow these steps to add the following disks to the cluster:
•The disk that contains the mount point
•The disk that hosts the volume for the mount point
a. Open the Failover Cluster Management snap-in. To do this, click Start, click Administrative Tools, and then click Failover Cluster Management. If the User Account Control dialog box appears, confirm that the action that it displays is what you want, and then click Continue.
b. In the navigation pane, click Storage.
c. In the Actions pane, click Add a Disk.
d. Select the disk that hosts both the mount point and the volume for the mount point, and then click OK. Disks now appear in the Available Storage area of the storage pane.
e. Right-click the disk resource that hosts the mount point, and then click Properties.
f. In the Resource column, click the Dependencies tab.
g. Click the root disk, click Apply, and then click OK. This dependency will cause the resource to come online after the disk resource that hosts the mount point is successfully brought online.
6.Right-click the newly added disk resources, and then click More actions.
7.Click Move this resource to Another Service or application to move the resource to the appropriate application or service group.
