I want to mount a CBFS volume in another CBFS volume.
That means the mounting point of the second volume is inside the first volume.
I tried to do that but when I set the mounting point of the second volume as a folder of the first one, an exception is thrown with the error "incorrect function".

Is it possible to mount a CBFS volume inside another one?

This is not possible, neither it makes much sense. If both points are managed within one instance of one application, it makes sense to build the directory tree (thus adding extra directories) within your application and expose this directory tree using one piece of code.

If you want different processes to make a nested virtual filesystem, this won't work due to specifics of OS design.

Make sure your code is thread safe by using locks/mutexes. That helped us fix problems with mounting volumes being read from other CBFS volumes.
