Hi -

Like Becky and I mentioned, you'll also need to start the pvfs2-client
daemon to be able to access the pvfs2-fs via the kernel module, only
then will you able to mount it.

So far all you've done is start up a metadata and io server, in the
typical client/server context this only amounts to starting the
server.

In order to access it via a 'client'-mode you need to load the
pvfs2.ko kernel module and the pvfs2-client
http://www.pvfs.org/cvs/pvfs-2-8-branch-docs/doc//pvfs2-quickstart.pdf
  check out ch5.4.1
