Hi,
Try
and I might, I can't get Mount Points displayed properly in a Windows 2012 R2 cluster.
In Windows 2008 R2, I added them, and they appear under Storage, as for Example, Cluster Disk 7: Mounted Volume (S:\SYSDB). (I may have had to bring them offline/online).
in Windows 2012 R2, they are showing up as, for example, '\\?\Volume{7c636157-e7e9-11e4-80dc0005056873123}'
In the error log it shows up as :
Cluster disk resource 'Cluster Disk 7' contains an invalid mount point. Both the source and target disks associated with the mount point must be clustered disks, and must be members of the same group.
Mount point 'SYSDB\' for volume '\\?\Volume{7c636106-e7e9-11e4-80dc-005056873123}\' references an invalid target disk. Please ensure that the target disk is also a clustered disk and in the same group as the source disk (hosting the mount point).
Now I've checked the error, and in https://technet.microsoft.com/en-au/library/dd353925(v=ws.10).aspx it says
"The mounted disk and the disk it is mounted onto must be part of the same clustered service or application. They cannot be in two different clustered services or applications, and they cannot be in the general pool of Available Storage in the cluster."
So I have created a 'Other Server' Role. When I go right click on the Role and go to 'Add Storage', Cluster Disk 6 (the root volume) displays S:\, and Cluster Disk 9 (hosting the mountpoint) says Mount Point(s): (S:\SYSDB). I select both, and add, but alas, the Mount Point still shows up as '\\?\Volume{7c636106-e7e9-11e4-80dc-005056873123}\ (not S:\SYSDB or Cluster Disk 6: Mounted Volume (S:\SYSDB).) as I would expect.
They are both clustered disks (iSCSI). I would expect when it says in the "same group", both added to the same role would be in the same group.
