Exchange database files are being written to a non-NTFS partition
Topic Last Modified: 2010-07-26
The Microsoft® Exchange Best Practices Analyzer Tool queries the Win32_Directory Microsoft Windows® Management Instrumentation (WMI) class to determine the value of the FSName key for the Exchange database file path. If the Exchange Server Analyzer determines that the value for the FSName key does not equal NTFS File System, an error is displayed.
Microsoft does not support the storage of Exchange data files on non-NTFS volumes. The Exchange data files include all the following files:
If you see this error, you must move the database files to a folder on an NTFS drive. Alternatively, if the drive on which the database files are stored is formatted as a FAT drive, you can use the convert.exe command-line tool to convert the drive to NTFS.
Open Exchange System Manager.
Expand Administrative Groups, expand your administrative group, expand Servers, expand your server, expand your storage group, right-click Mailbox Store, and then click Properties.
On the Database tab, under Exchange database, or Exchange streaming database, click Browse, type the path location to a folder on an NTFS volume, and then click OK.
Click OK or Apply to apply your changes, or click Cancel if you do not want to apply your changes.
If you clicked OK or Apply, you receive the following warning message:
Note You are about to perform the following operation(s)
change the Exchange database location
change the Exchange streaming database location
To perform the requested operation(s), the store must be dismounted which will make it inaccessible to any users.
Do you want to continue?
Note: Only the operations that you have chosen are listed in the warning message. The warning message contains a Yes and a No button.
- change the Exchange database location
Click Yes if you are ready to proceed, otherwise click No.
If you clicked Yes, the stores (databases) are dismounted, moved, and remounted. When these procedures are successfully completed, you receive the following informational message:
The database files have been moved successfully
Follow the guidance in the core Exchange Server 2007 documentation, "How to Move a Storage Group Path" (http://go.microsoft.com/fwlink/?LinkID=80747 )
Follow the guidance in the Exchange Server 2010 documentation, Move-DatabasePath
If the drive on which the files are stored is formatted as a FAT drive, you can also use the convert.exe command-line tool to convert the drive to NTFS. For information about how to use the convert.exe command-line tool to convert a FAT partition to an NTFS partition, see Microsoft Knowledge Base article 214579, How to Use Convert.exe to Convert a Partition to the NTFS File System.
