I know what you mean. I just gave the example, in the case the path of
iozone is incorrect, what would happen, And the result is the error
below will be print out:
>> bash: /tmp/iozone: No such file or directory
I just tried to proved that the path of iozone in my nodes is correct.

Now, I almost gave up iozone. I have tried iometer, which is better at
testing parallel fs as I know. It's very easy to config and run.
