Backup failing with Unexpected error 0x54e on GlobalClusterLatest.4096.dat RRS feed

  • Question

  • Hi,

     

    All backups started failing since yesterday evening with the following repeated error messages:

     

    Code Block

    Event Type: Error
    Event Source: HomeServer
    Event Category: Backup
    Event ID: 272
    Date:  07.12.2007
    Time:  01:29:36
    User:  N/A
    Computer: HOME
    Description:
    Unexpected error 0x54e from OpenOldGlobalClusterLatestFile on D:\folders\{00008086-058D-4C89-AB57-A7F909A47AB4}\GlobalClusterLatest.4096.dat: Unable to complete the requested operation because of either a catastrophic media failure or a data structure corruption on the disk.

    This was preceded by another error message a few hours earlier:


    Code Block

    Event Type: Error
    Event Source: HomeServer
    Event Category: Backup
    Event ID: 272

    Disks are fine, chkdsk OK, the server-storage diagnostics found a few "Permission is not consistent with Tombstone. Tombstone-Shadow mismatch" errors, but nothing significant.

     

    There is an "1th Ace Sidstart mismatch. Permission is not consistent with Tombstone. Tombstone-Shadow mismatch" error on "GlobalClusterLatest.4096.dat", but this error seems to exist on many other files...

     

    This is a plain-vanila OEM WHS, will all the latest patches, running two plugins: "Duplication Info 1.1.0.0" and "KeepVault 2.15". I now also has the "Windows Home Server Toolkit"...

     

    If I understand things correctily, GlobalClusterLatest.4096.dat is the file that contains all the cluster hashes.

     

    Does anyone have an idea what would happen if I erased this file? Would Backup rebuild it or will this hose all the backups?

     

    Any suggestions?

  • SErmann, are you still experiencing this issue? At present there is no tool to rebuild the backup database. A few errors can be fixed manually, but for the most part you will have to delete your backup database and start over for the time being.

  • Hello Ken,

     

    Thank you for following up. I tried various techniques, but nothing worked, except deleting the backup database and start again.

     

    Best regards,

  • Hi,

     

    Erasing the GlobalClusterLatest.4096.dat file stops the WHS Backup crashing and backups now seem to run normally, but

    • There is still an "Backup Server Error: A possible database consistency problem has been detected in the backup database" error in the Home Network Health dialog;
    • Backup Cleanup does not work: it starts and stops very quickly (23 seconds), old backups are not removed

    Any suggestions about how to rebuild the backup database?
