FIO is very flexible io generator, i would call it IO swiss knife. Currently we have tonns of hardcoded application which reproduces some predefined scenario. This approach has obvious dissadvantages 1) Lack of flexability: one written it is hard to modify it in future 2) Code base is large, many routines written again and again At the same time add new fio based tast is just add simle INI file. This greatly simplify code review. I do beleve that some day we will replace most of hardcoded io binaries with fio. One who is planning to run $FIO_PROG should first check that system contains appropriate version which is able to handle jobfile for example: _require_fio 286-job.fio Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> --- common.config | 1 + common.rc | 15 +++++++++++++++ 2 files changed, 16 insertions(+), 0 deletions(-)
