fio [options] [job options] <job file(s)>
--debug=options Enable debug logging. May be one/more of:
process,file,io,mem,blktrace,verify,random,parse,
diskutil,job,mutex,profile,time,net,rate

--terse-version=x Set terse version output format to 'x'
--version Print version info and exit
--help Print this page
--cpuclock-test Perform test/validation of CPU clock
--crctest Test speed of checksum functions
--cmdhelp=cmd Print command help, "all" for all of them
--enghelp=engine Print ioengine help, or list available ioengines
--enghelp=engine,cmd Print help for an ioengine cmd
--showcmd Turn a job file into command line options
--eta=when When ETA estimate should be printed
May be "always", "never" or "auto"
--eta-newline=time Force a new line for every 'time' period passed
--status-interval=t Force full status dump every 't' period passed
--readonly Turn on safety read-only checks, preventing writes
--section=name Only run specified section in job file
--alloc-size=kb Set smalloc pool to this size in kb (def 1024)
--warnings-fatal Fio parser warnings are fatal
--max-jobs=nr Maximum number of threads/processes to support
--server=args Start a backend fio server
--daemonize=pidfile Background fio server, write pid to file
--client=hostname Talk to remote backend fio server at hostname
--idle-prof=option Report cpu idleness on a system or percpu basis
(option=system,percpu) or run unit work
calibration only (option=calibrate)

可以使用之前写的脚本：

脚本入参说明：
- 第一个参数：datadir，fio测试文件的目录
- 第二参数：runtime， 单个测试项的持续时长，单位：秒
- 第三个参数：filesize，测试文件的大小，默认为
10GB
切记：
- 理解脚本内容后，方可在现场环境执行。
- 如果要执行fio命令的file参数为磁盘路径，谨记不要在系统盘、有数据的磁盘上直接测试。
脚本对如下场景进行测试：
- 随机读
- 顺序读
- 顺序写
- 随机写
- 读写混合，写占30%
- 读写混合，写占70%
测试结果示例如下：
| 测试项 | 指标 | adb01 |
|---|---|---|
| 随机读 | bw | 13409KB/s |
| iops | 1676 | |
| 顺序读 | bw | 1108.2MB/s |
| iops | 141950 | |
| 顺序写 | bw | 145554KB/s |
| iops | 18194 | |
| 随机写 | bw | 14209KB/s |
| iops | 1776 | |
| 混合随机读写 （写占 30%） 上读下写 | bw | 11491KB/s |
| iops | 1436 | |
| bw | 4961.9KB/s | |
| iops | 620 | |
| 混合随机读写 （写占 70%） 上读下写 | bw | 4641.8KB/s |
| iops | 580 | |
