I am trying to run the basic bench test on the Gluster cluster from this GitHub repo<https://github.com/gluster/gbench/tree/master/bench-tests/bt-0000-0001>. I also have IOZone installed. While trying to run the provided script, i get the following error. I was trying to identify the cause of the error. Kindly help me with that.

Hi Menaka,

Thanks for taking a look at gbench. It appears that you have uncovered a bug in
our documentation and code.

Shyam is the expert here and I'll let him chime in. You need an environment
variable with CLIENTS and SERVER to get this working. So when you run this, you
need at least two machines (VMs would be best. Happy to guide you on how to set
this up if you'd like). It would look something like this:

CLIENTS="" SERVERS="" python GlusterBench.py -s 64 -f 10000 -n 5 -v

I'm making a lot of assumptions here. If there's anything that is confusing,
let me know and I'm happy to clarify. I'll let Shyam jump in later today (he's
in EST) to chime with anything else I've missed.
