perfSONAR User Q&A and Other Discussion

[Emanuel Gull <>]

Hi,

I have a beginner user’s question: after following the docker instructions here:

http://docs.perfsonar.net/release_candidates/4.1b1/install_docker.html

And getting great results on a MacBook Pro, I reran the same commands on a Synology disk station with docker and got the following output:

[root@fermi /]# pscheduler task throughput --dest perfsonar-dc-macc.umnet.umich.edu

Traceback (most recent call last):

  File "/usr/libexec/pscheduler/commands/task", line 504, in <module>

    timeout=10

  File "/usr/lib/python2.7/site-packages/pscheduler/psurl.py", line 103, in url_get

    return curl(json, throw)

  File "/usr/lib/python2.7/site-packages/pscheduler/psurl.py", line 81, in __call__

    return (status, json_load(text))

  File "/usr/lib/python2.7/site-packages/pscheduler/psjson.py", line 123, in json_load

    raise ValueError("Invalid JSON: " + str(ex))

ValueError: Invalid JSON: No JSON object could be decoded

Is this a known problem documented somewhere? Am I doing something obviously wrong?

Best regards,

Emanuel
