  19 # Description:
  20 # Trigger fio runs using the random_writes job file. The number of runs and
  21 # data collected is determined by the PERF_* variables. See do_fio_run for
  22 # details about these variables.
  23 #
  24 # Prior to each fio run the dataset is recreated, and fio writes new files
  25 # into an otherwise empty pool.
