thanks for the bug report and the log.
There are some MPI-IO features that are not supported on PVFS:
- Shared file pointers requre explicit file locks, which PVFS does not
suport
- Orderd mode also relies on the shared file pointer, so that's not
supported either
Can you try out the tests in 'src/mpi/romio' ? you can just do a
"runtests -fname=/pvfs/whatever"
For the async I/O test we might have to get the orangefs guys
involved.
