Hi Tobias

I'm super-excited to see someone else besides a ROMIO developer use
the file system prefix!

Do you happen to have PVFS mounted also?

I strongly suspect that the HDF5 test here assumes that it can do
'open(/mnt/pvfs2/filename)' -- i.e. access the HDF5_PARAPREFIX
directory through the VFS.  I hammer those guys on this point time and
time again.  It looks like this new test is buggy with respect to
ROMIO filenames.  

I'll take this up with the HDF5 guys and we'll see if we can get a fix
to you.  In the meantime, try running all the other tests (run with
-exclude calloc)  and let us know if all the other tests still pass.

Thanks!
