If the cluster cannot be taken offline to backup your vRealize Operations Manager multi-node cluster by using vSphere Data Protection or other backup tools, disable quiescing of the file system.

Procedure

  1. Log in to the ESXi host with an SSH session, and power off all nodes.
  2. Navigate to the /vmfs/volumes/virtual_machine_datastore/ virtual_machine/ directory, and open the virtual_machine.vmx file for editing.
  3. Set the disk.EnableUUID parameter to false.
    You may have to add the disk.EnableUUID parameter to the virtual_machine.vmx file.
  4. Save and close the file.
  5. Power on all nodes.
  6. Open a console session to the virtual machine, and log in to each node.
  7. Navigate to the /etc/vmware-tools directory, and open the tools.conf file for editing.
    If you cannot locate the tools.conf file, run the vi tools.conf command to create a file.
  8. Add these parameters to the file. 
    [vmbackup] 
enableSyncDriver = false
    This runs a synchronization operation before the snapshot, and does not run a freeze on the file system.
  9. Save and close the file.
