perfSONAR User Q&A and Other Discussion

["Garnizov, Ivan" <>]

Hello Murilo,

 

Here is a statement in the pS Doc about pScheduler running without any limits configuration:

http://docs.perfsonar.net/config_pscheduler_limits.html#installing-a-limit-configuration

 

Warning

 

If the configuration file does not exist, is removed or fails to load, pScheduler will enforce no limits and grant every task request it receives. For this reason, it is strongly recommended that configurations be verified as described in Checking Limit Configuration Files for Validity before they are installed.

 

I hope that clarifies the operation of pScheduler or at least leads you to the proper conclusions.

 

 

Regards,

Ivan Garnizov

Betreff: Re: [perfsonar-user] PSCHEDULER BUG: Pscheduler maximum limit amount of time to schedule a task

 

Hi Mark

 

To exemplify better what I was saying that it does not show server site test, I send the file attached.

 

Hope it helps to identify the problem.

 

Regards,

Hi Mark,

 

One thing that I was thinking about is that in our scenario, we are deleting file: /etc/pscheduler/limits.conf

 

The purpose of that was to bypass some limitations imposed by default restrictions.

 

We would like to run long time period tests. In the past, we already run this kind of test invoking directly iperf3 tool.

 

Do you think could it interfere in anything? If pscheduler does not find the limit file, are there default values it consider?

 

Bests,

Hi Mark,

 

As I could understood, long time tests in versions 4.2.* it is now outputing the results.

 

And in the versions 4.1.4 and 4.1 it is writing the results from client side, but the server side is not report anything.

 

Version 4.1 and 4.1.4, when trying to run:

 

pscheduler result --diags https://10.39.2.2/pscheduler/tasks/43b8933b-a910-4ed3-a031-73a315f094f5/runs/9c7a523f-2b40-4aa0-8d6d-ff927ccc0ac7

 

The server side outputs:

 

Diagnostics from 10.39.2.6:

    (No diagnostics)

 

Error from 10.39.2.6:

    iperf3 returned an error: 

    Process took too long to run.

 

The schedule tests:

 

[root@470fce348303 /]# pscheduler schedule -PT1H

2019-12-03T10:17:01-05:00 - 2019-12-04T10:07:03-05:00  (Finished)

Is something that I am missing?

Hi Mark,

 

We already tried to run this on perfsonar docker images:

- Latest (4.2.2)

- v4.2.1

 

Now I am going to try to run on 4.1.4 to see if it is going to have problem.

Do you know if it is a problem on newer version 4.2.*?

 

The code that covers this hasn’t changed since it was first written, so I would expect the behavior to be the same on all versions.  We’re planning a bugfix release in the next few weeks; whatever fix I come up with will likely ship with that.  I’ve been up to my neck in SC for most of the last month and now am up to my neck in TechEx, so your patience is appreciated.
