   A meta volume should be created with RAW status that the volume was not formatted, when creating a separate volume. WDRBD accesses to a meta volume as a sector unit basically, therefore, some part of a sector may not accessible because those are protected because of result from request for an authority to write against a boot record area if the volume has been formatted through the particular file system such as NTFS type. Moreover, it would not be able to use as a meta disk for WDRBD because a meta area of the file system such as MFT is made. So it is recommended choosing the option for what the volume is not formatted when creating the initial volume.
