>  3. Login to machine; create temp/test directories on data volume and write sample data into it
>  4. Snapshot the Volume
>  5. Create another Volume from snapshot
>  6. Mount/Attach volume to another VM
>  7. Now compare the data on the volume, data should match
> The directories and files created earlier exist on the volume, but the data in the files is garbage data instead of the data we have written into the volume earlier.
> Data is not matching.
