Hi,
I'm having some trouble getting the parallel hdf5 tests to pass using
mpich2 and pvfs2. Below is the result of the following commands which
runs the hdf5 tests:
export HDF5_PARAPREFIX=pvfs2:/mnt/pvfs2
./testphdf5
Testing -- fapl_mpio duplicate (mpiodup)
Testing -- fapl_mpiposix duplicate (posixdup)
Testing -- dataset using split communicators (split)
Testing -- dataset independent write (idsetw)
Testing -- dataset independent read (idsetr)
Testing -- dataset collective write (cdsetw)
Testing -- dataset collective read (cdsetr)
Testing -- extendible dataset independent write (eidsetw)
Testing -- extendible dataset independent read (eidsetr)
Testing -- extendible dataset collective write (ecdsetw)
Testing -- extendible dataset collective read (ecdsetr)
Testing -- extendible dataset independent write #2 (eidsetw2)
Testing -- chunked dataset with none-selection (selnone)
Testing -- parallel extend Chunked allocation on serial file (calloc)
Proc 0: *** PHDF5 ERROR ***

Ok; all servers understand fs_id 1470828028

Root handle: 1048576
Ok; root handle is owned by exactly one server.
=============================================================
The PVFS2 filesystem at /mnt/pvfs2 appears to be correctly configured.
My build procedure is as follows:
PVFS2 (2.7.0)
./configure --prefix=/home/tbrandvik/pvfs2
MPICH2 (1.0.6p1)
./configure -prefix=/home/tbrandvik/mpich2
--with-pvfs2=/home/tbrandvik/pvfs2/ --enable-sharedlibs=gcc
HDF5 (1.6.6)
./configure -prefix=/home/tbrandvik/hdf5 --enable-parallel
--enable-shared CC=mpicc CXX=mpicxx
This is all on CentOS 5.
There was a thread on the list a while back dealing with the same
issue, but with different tests failing:

Does anyone have any ideas about why the tests are failing?
Tobias.
