I guess I understand when fio "stops" when using 1 file per job: after `io_size` IOs, which is usually the same as `size` if `io_size` has not been specified explicitly. When size == io_size, this means that all blocks of the files are written exactly once with linear or random writes, except if norandmap=1, in which case some blocks will likely be written 0 times and others 2 or more times. How does this work for nrfiles > 1 and linear writes (rw=write) and file_service_type set to one of the random ones? For the non-uniform distributions some files will be written at a higher rate than others: does the write pointer just loop when it gets to the end of the file? So io_size writes will still be done, but some files will not be completely written while others may be written more than once? Travis
