converting the RO to an RW Volume consists mainly of three parts:
- converting the volume special files, e.g. the content of the info file=20
  and a kind of renaming of the all special files =20
- converting the volume header file, which contains the inodes of the=20
  volume special files=20
- replacing the vldb entry for the volume

I have only dealt with the namei fileserver because
- it was part of Hartmut's changes to MR-AFS
- we don't need it for non-namei fileservers.

I have no idea how difficult it would be to implement it for non-namei=20
servers, but I think, it shouldn't be expensive.
