DFSR Repliaktion Problem

Discussion in 'File Systems' started by André Heublein, Jun 5, 2007.

  1. Hi @ all,

    we have 3 Windows 2003 Sp2 R2 servers, 2 of that are the namespace-server.
    All 3 Servers are only member server, not DC.

    There are 6 folder targets, and the target referral per target are only
    active on 1 of the three servers.

    Problem: There are many files & folders, that are moved to the
    conflict&delete folder in DfsPrivate-Folder.

    In the event log the ID 4412 are logged:

    Event Type: Information
    Event Source: DFSR
    Event Category: None
    Event ID: 4412
    Date: 05.06.2007
    Time: 12:28:55
    User: N/A
    Computer: server02
    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: D:\data\xxxxxx\xxxxxxx
    New Name in Conflict Folder:
    xxxx-{657A4CE1-6830-4821-92B0-189BF7561348}-v89002
    Replicated Folder Root: D:\DATA
    File ID: {657A4CE1-6830-4821-92B0-189BF7561348}-v88878
    Replicated Folder Name: DATA
    Replicated Folder ID: EBB6D131-6831-4AFC-BBE4-7241AFAA4F77
    Replication Group Name: domain.intranet\dfs\data
    Replication Group ID: 5AE4DD7D-A7EE-4947-82D1-1BB4E40C70A1
    Member ID: E86CF603-FEC1-42CF-94BD-C80172EA540B


    This event are logged on all 3 servers, on the server, who was the referral
    server, most often as the other servers.

    Past 1 week we installed Service Pack 2 on this servers and a few days ago
    the error went away.
    Since 1-2 days the failure is coming back.

    On the servers we have not running a virus scanning application and i don´t
    know, which service/program are open/change the files, so the dfsr service
    thinks, the files are changed on both or 3 servers.
    This are only file-server.

    The clients are windows XP Sp2, on the same network, but in different
    subnet´s, routet via RoutingSwitch.

    Can anyone reconstruct this problem? Or has anyone the same problem and
    knows, how to "repair" it?

    Thanks for your help

  2. File conflicts (event ID 4412) are not an error condition. The event is an
    informational event telling you a file was updated on more than one member
    before the changes had time to replicate. Since you have three servers
    replicating with DFSR, and all three servers are accessible to users as DFS
    targets, it is possible that users themselves are causing this. If one user
    changes a file on server A at the same time another user changes it on
    server B, DFSR resolves the conflict for you and moves the conflict loser to
    ConflictAndDeleted.

    In the DFSR debug logs, the USN Consumer (USNC) entries have a Reason: field
    that shows what type of change was made to the file. To tell who/what made
    the change, you need to enable NTFS auditing on the folders you care about
    monitoring.

  3. I've seen that in a few cases:

    1. A bug - but you put SP2 on and that loophole is closed with the latest
    DFSR.EXE service executable.
    2. Poorly written anti-virus software - it was scanning the replicated
    folders, adding alternate data streams to files and causing conflicts and
    reanimations that led to conflicts.

    Buuuuut... you cut both of those out nicely. :)

    In order to troubleshoot this we will need access to your DFSR debug logs
    from all three servers, file system filter driver info, as well as the
    conflictanddeletedmanifest.xml data. I suggest opening a case with us here
    in PSS for deeper analysis - conflict cases like this are pretty much
    one-off's usually if not the above 2 things. If you have a Premier contract
    you can open through normal channels. If not, you can open a per-incident
    case with our Professional support here:

  6. Hey andre..

    m facing the similar issue here we have two server and replication from Primary to other server is not happing. i am getting multiple below events in event viewer

    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: E:\Data\DDOC1\Data\Opodo\data\r\rrieaaaa.b
    New Name in Conflict Folder: rrieaaaa.b-{3FA94DA0-079A-4A7A-88BC-29BF8AD5ECD7}-v2867669 The problem i am suspecting is that be have cleaned out primary folder some time ago and those contents still exist in other server. i belive that is making this issue..

    also the other server has Waiting for initial replication error in DFSR logs

    any help?
