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.
