VMWare Workstation 12 Pro --- How to repair the vmdk disk if the defragmentation fail

I am not sure why the defragment fail when want to defrag the VMDK disk on the VMWare Workstation. It just tell me that the specified vritual disk needs repair!

How to do it?
As before, I will please Google help to search the related information for resolving this problem. Thanks Google let me to find out one KB on the VMWare Official Web. That is KB --- Repairing a virtual disk in Workstation (2019259)

According to this content, it clearly teach us to do the following command# /usr/bin/vmware-vdiskmanager -R <path of the vmdk(virtual disk)>
        Note: Where < path of the vmdk(virtual disk)> is the folder path to the virtual disk that appeared in the error.

Once the above process finish successfully, we can do the defragment virtual disk now.
