SYMPTOMS

On a Windows Server 2003 R2-based Distributed File System Replication (DFSR) server, you try to update a file that has a newer version on the DFSR downstream member. The operation fails. Event 4412 and event 4502 are logged in the DFS Replication event log. Event 4412 indicates a conflict, and event 4502 indicates a disk full situation. Also, the file is deleted from the replication partners. Therefore, the file disappears on the DFSR upstream member.

Event 4412 resembles the following event:

Event Type: Information
Event Source: DFSR
Event Category: None
Event ID: 4412
Date: Date
Time: Time
User: N/A
Computer: Computer name
Description: The DFS Replication service detected that a file was changed on multiple servers. A conflict resolution algorithm was used to determine the winning file. The losing file was moved to the Conflict and Deleted folder.

Additional Information:
Original File Path: File path
New Name in Conflict Folder: Folder name

Replicated Folder Root: Folder name
File ID: File ID
Replicated Folder Name: Folder name
Replicated Folder ID: Folder ID

Member ID: Member ID

Event 4502 resembles the following event:

Event Type: Warning
Event Source: DFSR
Event Category: None
Event ID: 4502
Date: Date
Time: Time
User: N/A
Computer: Computer name
Description: The DFS Replication service encountered errors replicating one or more files because adequate free space was not available on volume Volume Name:. This volume contains the replicated folder, the staging folder, or both. Please make sure that enough free space is available on this volume for replication to proceed. The service will retry replication periodically.

Note Event 4502 occurs even if there is sufficient free space in the volume where you have the DFSR Staging folder and the Replicated folders.

CAUSE

The DFSR service may delete existing files when it tries to update these files after the service receives an ERROR_DISK_FULL error. This disk full error may be caused by insufficient real disk space or by some disk quota software.

This problem occurs because the earlier version of the file is moved into the DfsrPrivate\Deleted folder. However, the new version of the file cannot be moved from the DfsrPrivate\Installing folder to the target directory because of the disk full error. Therefore, the processed deletion of the file is confirmed as a local file change, and then replicated on the replication partners.

WORKAROUND

To work around this problem, do not use disk quota software together with hard quota limits on the volumes that contain the DFSR Staging folder and the Replicated folders.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

If you use hard quota limits together with DFSR, the DFSR service may still be able to replicate a file, stage the file accordingly, and then prepare it in the DFSRPrivate\Installing folder for the final move. However, the file may not be moved to the target folder. In this case, the ConflictAndDeletedManifest.xml file may become corrupted.
