At first Thank you very much for your time. "--with-file-system=pvfs2+ufs+nfs" didnt help. But if find (by google) some part of orangefs test. I dont know what is this exactly doing, but when I edited source code of OpenMPI like doing this line, all seems that it is working now. (changing ADIOI_PVFS2_IReadContig and ADIOI_PVFS2_IWriteContig to NULL in file ad_pvfs2.c) http://www.orangefs.org/trac/orangefs/browser/branches/OFSTest-dev/OFSTest/ OFSTestNode.py?rev=10645#L1328 Other tests I will do tomorrow.
