H5D_FILL_TIME_IFSET Write fill values to the dataset when storage space is allocated only if there is a user-defined fill value, i.e., one set with H5Pset_fill_value. (Default)
My first interpretation was, that the fill value is written if it is defined. However, it is only written if it is defined and not the default value.

I tried with and without setting H5Pset_fill_time(h5p, H5D_FILL_TIME_NEVER) for chunked and continuous variables. There is no difference in the called MPI functions and the datasets contain zeros in both cases (according to h5dump). Does H5Pset_fill_time make a difference when MPI IO is used?By default the fill value is zero (see http://www.hdfgroup.org/HDF5/doc/RM/RM_H5P.html#Property-SetFillValue) so you may want to set it to another value to test this feature.
