39 echo "usage of $PROG:"
41 -h : Show this help & exit
42 -c : Enable cached-based IOs
44 -a : Run sequential test then parallel one
46 -s : Run sequential test (default value)
47 one test after another then one disk after another
49 -p : Run parallel test
50 one test after anoter but all disks at the same time
52 -D iodepth : Run with the specified iodepth
54 -d disk1[,disk2,disk3,..] : Run the tests on the selected disks
55 Separated each disk with a comma
56 Disk name shall be "sdxx", /dev/ shall NOT be used here
57 -r seconds : Time in seconds per benchmark
58 0 means till the end of the device
59 Default is 300 seconds
60 -b blocksize[,blocksize1, ...] : The blocksizes to test under fio format (4k, 1m, ...)
61 Separated each blocksize with a comma
63 -m mode1,[mode2,mode3, ...] : Define the fio IO profile to use like read, write, randread, randwrite
64 Default is "write,randwrite,read,randread"
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
