Azure scratch VHDX corruption? RRS feed

  • Question

  • Hello

    DPM 2016 with MBS, Server 2016, MARS Agent 9077 - Protection of a Server 2012 R2 volume with dedup enabled.

    My online recovery points have suddently stopped working with the following error:

    Online recovery point creation jobs for Volume J:\ on XXXXXX have failed 1 times. (ID 3188)
    Unable to find changes in a file. This could be due to various reasons. Please retry the operation. (ID 32504)

    Upon lots of searching and troubleshooting I have dug as deep as mounting the Azure scratch VHDX and upon running chkdsk recieve the following:

    Stage 1: Examining basic file system structure ...
    Attribute record (80, "") from file record segment 1E48
    is corrupt.
    Attribute record (80, "") from file record segment 4CCB


    Errors found.  CHKDSK cannot continue in read-only mode.

    I am unable to run CHKDSK with the /F as the volume is write protected, the VHDX IS NOT mounted in read-only mode.

    Any advice on what to do next please?

  • I have disabled deduplication on the protected volume (from the source server) and run an unoptimization job. The protection group has synced and I have run a consistency check. It seems the local replica's are working fine but the online recovery points are still failing with the same errors.

    I can see lots of errors in the CBEngineCurr.errlog relating to the volumes relating to this data and the ID32504 error.

    Any help appreciated.
