Shared volume backup crashes DPMRA agent RRS feed

  • Question

  • Hello,

    currently a backup of one of my shared volumes on a clustered fileserver crashes the DPMRA agent and would like some pointers what could be the issue.

    I am backing up a shared volume (located in a 2012R2 Fileserver cluster) using DPM 2012R2.
    The volume is a shared VHDX, attached to 2 the 2 cluster nodes. Backup happens from with the VM.
    The cluster has 2 shared volumes: One can be backed up without issue, but the other one causes the DPMRA service to crash.

    I checked the agent errlog, but that gave me nothing.
    Here the last few lines:

    I tried:

    • Consistency check
    • Removing the drive from the protection group and re-adding it
    • Restarting the server nodes of the cluster
    • Restarting DPM

    None of these steps solved the issue.

    I would very much appreciate some suggestions as to what could be causing the issue.

    Thanks in advance
