Hi Nachiappan, I don't believe there is a full guide explaining PVFS with MPICH2. A first step may be to take PVFS2 out of the equation and make sure you have a working MPICH2 environment and then add PVFS2 back. It appears you're following the right install guides so your setup may just need a little tweaking. I know there are several people on the list with lots of MPICH2/PVFS experience who may be able to provide some more specific pointers.
