could not get graph for a slice in Geni Desktop

[Gandhimathi Velusamy]

Hi,

My slice name is distlinc and  I am testing with Hadoop application  and when I tried to get graph,  it is not showing any graph.  Even I tired with Ping from one host to another and checked the icmp graph and not able to see it. So thought of testing with another slice and created a slice with simple two node topology and able to get graph. What might be the reason for not able to see any graph for the slice named distlinc. 

Thanks

Gandhimathi

Okay if it was not the clemson racks, that could be my answer to your problem. Can you try your same rspec at any other rack ? (the one that does not work.) I suspect that there is a problem at the clemson racks where in any node with a public IP cannot talk/connect/ping to other nodes in the same slice over the control network. I will contact the concerned person at the rack to figure out the problem.

cheers,

Is there any way to see the expired slices on the current project. I forgot the slice name but I have created it on the demo date on GEC-20. I have seen from my mail that it may be 'distributedlinc' from bbn instageni rack. In Portal the expired slices button is disable and I could not get rspec for that. 

Thanks.

I have replicated your problem and know whats causing it which i can currently blame on the rack. But i wanted to see the behaviour on the working one. Can you give me the rspec for the one that worked and the rack name you used it on ?

I am sorry, I forgot to tell you that the slice got expired. 

But the slice distlinc is now can be viewed in Geni-Desktop. It is not showing any error. but I am not getting any graph.

Thanks.

Which rack do you have resources on that works ? I suspect it is the rack at fault, but have to run more tests to confirm this theory .

Hi  Nasir,

As I am working on Hadoop, I took master and slave as raw PCs to run Hadoop application. I am able to login with master and slave nodes and able to run my experiment, then how do you say that there are no free raw PCs. I run several runs of the Wordcount problem on them and able to get output. I was trying to see the traffic going by the Software switch connecting them vis GENI-Desktop but coudn't able to get it. When I created the slice it was showing Geni desktop on next action field but now it is showing only FLACK and also it is showing no resources found. 

But now also I able to run the experiment on the master and slave nodes.

As you can I now change the rspec now and submit it again. Will it work, I know that in FLACK after resources have been allocated by clicking on the submit button we can't make any changes in slice and on allocated resources right. OR do you mean to say I need to create a new slice with modified rspec which contains VMs for master and slave?

Can't we get graphs from GENI-Desktop for a slice which is having PCs in them. OR something happen in the middle so that I am seeing 'No resources found' from Geni-Desktop. But right from the beginning I didn't get graph for this slice.

But I am having one more slice with the same topology with all VMs and able to get graph from Geni- desktop..

Thanks.

Hi Gandhimathi,
   Looking at your rspec i see that you have two raw nodes (Master, Slave). DId you change this to xen VMs becasue this rspec would never work as the racks do not have any free raw PCs.

Hi Nasir,

Please, find attached Rspec for the slice named distlinc for which I couldn't get any graph.

Thank you for your follow-up even though you are on vacation. No problem, I just want to know why for the particular slice I am not getting the graph and want to know whether  I  have missed anything.

Thanks.

Hello Gandhimathi,

Can you please also send us the rspec you had used ? Sorry i could not get back to you earlier since i am on vacation right now and will be out until end of next week (July 25) so i may not be able to get back to you soon on this.

I am also ccing the GEMINI Dev team just in case someone else can try this out and see why this fails.
