LUN Backup in progress, Redirected Access - all the time RRS feed

  • Question

  • Good morning everyone.


    I have a problem on my Hyper-v cluster, I have a LUN that is at all times with access redirected.


    1 Server with Microsoft Windows Server 2008 R2 SP1 + DPM 2010.
    4 Servers with Microsoft Windows Server 2008 SP1 + R2 Hyper-V Role

    I have been working perfectly with the environment to 6 months without any problems.

    At the end of last week came a warning event 1584 in one of the cluster members.

    "The backup application VSS snapshot initiated on Cluster Shared Volume 'Storage_FT' ('Cluster Disk 2 - FT') without Properly preparing for the snapshot volume. This May Be invalid snapshot and the backup May Not be usable for restore operations. Please contact your backup application vendor to verify compatibility with Cluster Shared Volumes "

    And after that DPM backups begin to fail.

    Some events appeared in the DPM 2010 server:

    Event ID - 10108 - Hyper-V-VMMS
    Event ID - 3114 - DPM-EM
    Event ID - 561 - Backup

    Has anyone gone through this problem??
