When you build mpich2 it looks in the standard place for pvfs2. If
you installed pvfs2 elsewhere then you need to configure mpich2 using
'--with-pvfs2=<path>'
If mpich fails to build then apply the patch to mpich available
from the link below.

Hi Everybody,
I recently compiled and installed mpich2-1.0.8 and pvfs-2.8.0. I am
using pvfs in user mode.
I wrote a program to open a file in write only mode. Whenever I
try to
open the file in a pvfs2 file system,
(filename is pvfs2:/export/home/patrick/pvfs2-fs/testfile)
I get an error
0: file: io.c, function: main, line:68 error_code: Other I/O error ,
error stack:
0: ADIO_RESOLVEFILETYPE(742): Specified filesystem is not available
However, I am able to open a file in a normal filesystem (I think
ext3/nfs/ufs).
Any ideas why this problem may be happening?
I tried debugging, but all I get is that it enters the function
"src/mpi/romio/adio/common/ad_fstype.c":ADIO_ResolveFileType and
then
prints the error message from line 741. The error message is
enclosed
in #ifndef ROMIO_PVFS2 ... #endif.
I dont understand why it is entering this and printing the error
message. I even reconfigured the pvfs2 filesystem, but it does not
solve the problem.
I tried searching the net and found the thread
http://www.mail-archive.com/[email protected]/msg01483.html
I even tried touching the file in the pvfs2 filesystem, but it
does not
work.
Please help me!
Thanks,
Christina.
