This isn't really what he wants to do is it? I think he wants to what what is more or less impossible and that is take four distinct file systems and magically merge the meta data into a cohesive single MGS/MDS while retaining all the data.
Like I currently have /a and /b that use MGS1 and /c and /d that use MGS2. How can I combine MGS1 and MGS2 into MGS3 and retain the data of /a /b /c /d?
