  • Unable to quiesce guest file system during snapshot creation
    Posted: 01-24-2017, 10:00 AM

    Hello -

    Currently there is a virtual server agent type backup job which runs on a client and I am seeing for some machines the following error (status - Partially completed) - failed unable to quiesce guest file system snapshot creation. 

    I took the following steps outside of the Commvault 11 SP6 product, I took a manual snapshot of the VM in our VCenter ESXi 6 environment. Unchecked the snapshot the virtual machine memory and then checked Quiesce the guest file system (needs vmware tools installed). It still did not work and I got a quiescing error in VMware. 

    I reached out to Vmware support for assistance and resolved the issue ( i can now run quiesce snapshots in VMware with the VMware Snapshot Provider service disabled) start the Windows Virtual Disk service:

    1. Log in to the Windows operating system as an Administrator.
    2. Click Start, type services.msc, and press Enter.
    3. Right-click the Virtual Disk service and click Start.
    If this does not resolve the issue, disable VMware snapshot provider in the affected virtual machine:
    1. Disable the VMware Snapshot provider service in the guest operating system.
    2. Restart the Volume shadow copy service
    My only question regarding this is will commvault have an issue backing up the machine if the VMware Snapshot Provider service is disabled?

    Hi Shan, may impact restores.  

    After the fix from VMWare, is it still failing to backup in CV?

    After applying the fix, the backup completes successfully in CV without the following message "Unable to quiesce guest file system during snapshot creation"

    Hi ShanRay,


    This usually works for us although some of the VMs it will work for a few days and then revert back to quiescing errors


    1. Login to VM.

    2. Open services

    3. Restart the COM+ Event System. This will restart 3 to 4 services.

    4. After COM+ finishes, start or restart the Volume Shadow Copy service
