perfSONAR User Q&A and Other Discussion

["Garnizov, Ivan" <>]

Hello Alan,

 

From your message it does not become clear if there were any issues during the installation. I would assume there might have been warning and/or errors for you to end up with a non-operational perfSONAR system after a clean install on Debian 9.

 

I would suggest you to:

-           start pscheduler in a debuging mode: pscheduler debug on

-          Run a troubleshoot command: pscheduler troubleshoot

-          Stop pscheduler debug mode: pscheduler debug off

-          Review the pscheduler logs: /var/log/pscheduler/pscheduler.log

 

 

Regards,

Ivan Garnizov

on BeagleBone Black, pscheduler did not, in general, function. Typical response when asking for apparently-any task is:

 

>localhost: Process took too long to run.

 

After copying pscheduler auth rules from a working toolkit to /etc/postgresql/9.6/main/pg_hba.conf and also copying the limits file from a CentOS toolkit, I am able to run tests to the Beaglebone from a remote pscheduler host, but still unable to intitate tests from the Beaglebone itself.

'troubleshoot' gets:

Does anyone recognize a symptom, or know of a shortcoming that prevents the pscheduler command line from working here?
