Re: [Gluster-devel] Need help with running bench test on Gluster cluster.

[Menaka Mohan]

Hello Nigel B,

Thank you so much for you reply. Recently, I have noticed few syntax errors on 
the code and I have corrected them. Kindly review the Pull request.

Since I do not have a laptop with good specifications, I am unable to use VMs. 
I tried and it crashed many times. So with the support of a college friend I 
have setup the environment in a lab and accessing it through Bitvise SSH 
client. With the process becoming more complex, I am learning more things.

I have thoroughly gone through Shyam's reply and working on it.

Regards,
Menaka M

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="192.168.0.1 192.158.0.2" SERVERS="192.168.0.3 192.168.0.3" python 
GlusterBench.py -s 64 -f 1 -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.

[Gluster-devel] Need help with running bench test on Gluster cluster.

[Menaka Mohan]

Hi,


I am Menaka M. I am interested in participating in this round of Outreachy 
under Gluster. I am new to this open source world. Kindly help me with the 
following query.


I have set up the Gluster development environment with two servers and one 
client. I am trying to run the basic bench test on the Gluster cluster from 
this GitHub 
repo. 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.

So, I learned more about IOZone and also the performance testing section in the 
Gluster docs. With that knowledge and to learn more, I have gone through the 
code and running iozone commands mentioned in the GlusterBench.py script 
individually.

If I am asking a very basic thing, apologies. I will quickly learn things.

Regards,
Menaka M
