Error in some VMware backups snapshots - (4275) Unable to consolidate Virtual Machine Disks

We are running a Netbackup Server 8.2 and two virtual machines presents  (4275) Unable to consolidate Virtual Machine Disks  error daily. 

Is this a Netbackup or a VMware issue?

The VMware version is 6.7.

 

  • Hello everybody

    Thanks for all contributions.

    The case was solved using this vwmare kb:

    https://kb.vmware.com/s/article/84475

    a- It could be vpxa-worker ----> this can be fixed by restart vpxa agent using the below commands:

    # /etc/init.d/vpxa stop

    # /etc/init.d/vpxa start

    b- It could be hostd or hostd-profiler ---> this can be fixed by restarting hostd agent using the below commands:

    # /etc/init.d/hostd stop

    # /etc/init.d/hostd start

     

  • Hello

    This is VMWARE related issue - ask your VM admins to deal with it.

  • Hello,

    Well, regarding the error, it says that the consolidation fails, which is in general because there are some snapshot locks somewhere, sometimes, there are "stuck" lock files on the backups host under /tmp/vmware-root/ or C:\Windows\TEMP\vmware-SYSTEM , make sure there is no lock file there for the specific VM, if yes, delete them and re-run your backup..

    digging into logs may, for example vxms at high verbosity, help you identify which file is causing the problem.

      I've seen where VM's are still locked even when there are no stale snapshots sitting in /tmp/vmware-root/ and there are no hung processes on the backup host as well. It's only a happened a few times but I needed to reboot the backup host.

  • Hi andrich2016 ,

    In addition to Hamza_H comment, also verified there are no stale snapshots. you can verify this by right clicking affected VM, point to snapshot manager and ensure there not stuck snapshots showing. 

    Let us know the outcome of your troubleshooting. Thanks
