Error creating database on new storage in SQL Server 2008 R2 Failover Cluster Via the Failover Cluster Manager, I recently added a new disk to an existing SQL Server 2008 R2 Cluster, running on Windows Server 2012 R2.

When attempting to create a database on this new storage, I get the following error:

Msg 5123, Level 16, State 1, Line 1
CREATE FILE encountered operating system error 5(failed to retrieve text for this error. Reason: 15105) while attempting to open or create the physical file 'J:\DATA\mydatabase.mdf'.
Msg 1802, Level 16, State 4, Line 1
CREATE DATABASE failed. Some file names listed could not be created. Check related errors.



I can manually add a file to J:\data
The new storage can be moved between nodes without any errors
The SQL Server Service Account has full control over the entire J:\ drive
The SQL Server Service Account has full control over the J:\DATA 
Here is a layout of the drive, you will notice that DATA is a seperate volume mounted inside J:\




Can someone please help me figure out why I am getting this error?

Update

From James, if I add a subdirectory to data, then the create database command works

CREATE DATABASE [MCO_DB] ON  PRIMARY 
( NAME = N'MYDATABASE_DB', FILENAME = N'J:\DATA\MYDATABASE\MYDATABASE_DB.mdf' , SIZE = 3072KB , FILEGROWTH = 1024KB )
 LOG ON 
( NAME = N'MYDATABASE_DB_log', FILENAME = N'J:\TRN\MYDATABASE_DB_1.ldf' , SIZE = 1024KB , FILEGROWTH = 10%)
GO
Operating system error 5 is a simple Access is denied you can always check those errors in the command prompt net helpmsg 5. 

Now Volume mount points are sometimes a bother. In Windows server 2000 the calcs.exe had an error and could not set the permissions on the underlying drive and the only way to do it was to mount the volume using a drive letter, set permissions on the root folder and then create a mountpoint. 

Later versions of windows should be able set the permissions on the mountpoint by using the /M switch so that


  cacls j:\data /g DOMAIN\ACCOUNT:f /M /E


Will grant the domain\account full permissions on the root of the drive mounted at j:\data, I still haven't leard to do this with icacls.exe and a comment how to do so will be well appriciated. 

As you have found out creating a subfolder on the mount point makes it possible for you to create an accesslist for that folder but there still seem to be issues with setting permissions on the root folder of the drive using the GUI.

Usually I dont bother with the calcs command and if I need to set permissions on the root I'll add a driveletter, set the permissions using the GUI and then remove the drive letter.
