40 echo "usage of $PROG:"
42 -h : Show this help & exit
43 -c : Enable cached-based IOs
45 -a : Run sequential test then parallel one
47 -s : Run sequential test (default value)
48 one test after another then one disk after another
50 -p : Run parallel test
51 one test after anoter but all disks at the same time
53 -D iodepth : Run with the specified iodepth
55 -d disk1[,disk2,disk3,..] : Run the tests on the selected disks
56 Separated each disk with a comma
57 -r seconds : Time in seconds per benchmark
58 0 means till the end of the device
59 Default is $RUNTIME seconds
60 -b blocksize[,blocksize1, ...] : The blocksizes to test under fio format (4k, 1m, ...)
61 Separated each blocksize with a comma
62 Default is $BLOCK_SIZE
63 -m mode1,[mode2,mode3, ...] : Define the fio IO profile to use like read, write, randread, randwrite
65 -x prefix : Add a prefix to the fio filename
66 Useful to let a context associated with the file
67 If the prefix features a / (slash), prefix will be considered as a directory
68 -A cmd_to_run : System command to run after each job (exec_postrun in fio)
69 -B cmd_to_run : System command to run before each job (exec_prerun in fio)
