one test after anoter but all disks at the same time
Enabled by default
-D iodepth : Run with the specified iodepth
- Default is 32
+ Default is $IODEPTH
-d disk1[,disk2,disk3,..] : Run the tests on the selected disks
Separated each disk with a comma
- Disk name shall be "sdxx", /dev/ shall NOT be used here
+-z filesize : Specify the working file size, if you are passing filepaths to -d
+ Disabled by default
-r seconds : Time in seconds per benchmark
0 means till the end of the device
- Default is 300 seconds
+ Default is $RUNTIME seconds
-b blocksize[,blocksize1, ...] : The blocksizes to test under fio format (4k, 1m, ...)
Separated each blocksize with a comma
- Default is 4k
+ Default is $BLOCK_SIZE
-m mode1,[mode2,mode3, ...] : Define the fio IO profile to use like read, write, randread, randwrite
- Default is "write,randwrite,read,randread"
+ Default is "$MODES"
-x prefix : Add a prefix to the fio filename
Useful to let a context associated with the file
If the prefix features a / (slash), prefix will be considered as a directory
+-A cmd_to_run : System command to run after each job (exec_postrun in fio)
+-B cmd_to_run : System command to run before each job (exec_prerun in fio)
Example:
-$PROG -d sdb,sdc,sdd,sde -a -b 4k,128k,1m -r 100 -a -x dellr720-day2/
+$PROG -d /dev/sdb,/dev/sdc,/dev/sdd,/dev/sde -a -b 4k,128k,1m -r 100 -a -x dellr720-day2/
Will generate an fio file that will run
- a sequential bench on /dev/sdb /dev/sdc /dev/sdd /dev/sde for block size = 4k with write,randwrite,read,randread tests
