DFS Replication Database Corruption

Question

_{Friday, November 14, 2008 7:46 PM}

I am trying to setup a several remote servers to replicate their data back to one central server.  The central server is a cluster node but the volume that I am replicating to is not shared storage for the cluster.  I keep getting  the following error message when I run the replication diagnostics report.

**A database problem is blocking replication on volume N:.  

  Affected replicated folders: All replicated folders on this server. 

  Description: The DFS Replication service was unable to recover from an internal database error on volume N:. Replication has stopped for all replicated folders on this volume until the database is automatically rebuilt. If the database is rebuilt successfully, replication will resume after the rebuilding is complete. If the database cannot be rebuilt, a separate event is generated. If you are seeing this error more than two times in seven days, we recommend that you run Chkdsk on the volume that contains the database. Event ID: 2104 

  Last occurred: Monday, November 10, 2008 at 4:42:20 PM (GMT-8:00) 

  Suggested action: For information about troubleshooting this problem, see The Microsoft Web Site.**  
 
I have removed the central server from the replication groups and recreated the replication groups a few times and I can't seem to get rid of this error.  My question is, is there a way to repair the DFSR database?? or maybe just wipe it out so I can start out fresh.....

Hi,

According to the following article, this error may be caused by lack of disk space or corrupt DFSR files.

Error event IDs 2014 and 2004 and other Error events may be logged when you try to perform a replication on a Windows Server 2003 R2-based server that has DFSR installed

1.       Please check the size of replicated folder and free space of the central server.

2.       Please check if the NT AUTHORITY\System account has Full Control permissions on "System Volume Information" folder.

3.       If there are enough free space, let’s try to delete the DFSR folder for troubleshooting.

a.        Stop the "DFS Replication" service on problem server.

b.       On the system drive on problem server, show hidden files and system protected files. Give all permission on "System Volume Information" folder to you.

c.        Double-click "System Volume Information", we should find DFSR folder. Backup this folder to avoid data loss.

d.       Delete all "DfsrPrivate" folder in DFSR if there are several subfolder.

Start "DFS Replication" service and test.

4.       If the error still occurs, please check the Hard Disk to make sure there is no Hard Failure. Run command "chkdsk e: /r" (without quotation mark).

5.       At the same time, please try to replicate without this server and let us know the result.

Thanks
