我们去查看iozone的man手册可以看到，这一段

-+m filename
              Used to specify a filename that will be used to specify the clients in a distributed measurement. The  file contains  one  line for each client. The fields are space delimited. Field 1 is the client name. Field 2 is the working directory, on the client, where Iozone will run. Field 3 is the path to the  executable  Iozone on the client.

由上述信息可知，配置文件有三行信息，第一行是机器名或者IP；第二行是挂载目录；第三行则是iozone的执行路径

[Clinet]    [mount_directory]   /usr/bin/iozone

而且在测试开始前，客户端之间要配置免密登录，配置完免密登录后，我们可以创建一个配置文件host.cfg

storage01  /mnt/  /opt/iozone
storage02  /mnt/  /opt/iozone
storage03  /mnt/  /opt/iozone
storage04  /mnt/  /opt/iozone

配置完，就可以开始测试了

export RSH=ssh

/opt/iozone -ceIT -i0 -i1 -i2 -+n -r 4k -s1g  -+m host.cfg -t4 -Rb /root/4k_distributed_performance_test.xls

执行完应该会输出下述信息

root@storage01:~# /opt/iozone -ceIT -i0 -i1 -i2 -+n -r 4k -s1g  -+m host.cfh -t4 -Rb /root/4k_distributed_performance_test.xls
