perfSONAR User Q&A and Other Discussion

["Garnizov, Ivan" <>]

Hi Johann,

 

Please check the current state with these commands:

 

-          curl http://perf-pwa.sanren.ac.za/pub/config/sanren_mesh_2019.json?format=psconfig

-          psconfig validate http://perf-pwa.sanren.ac.za/pub/config/sanren_mesh_2019.json?format=psconfig

 

I believe these should give you an idea of what’s wrong on the system.

 

 

Regards,

Ivan Garnizov

Subject: [perfsonar-user] Docker testpoint is not downloading the meshconfig file

 

Hi all

 

My docker testpoint is not downloading it's meshconfig file (verified with tcpdump on both the docker host and on my PWA server)

 

[root@ps-100-100g /]# psconfig remote list
=== pScheduler Agent ===
[
   {
      "bind-address" : "155.232.40.194",
      "url" : "http://perf-pwa.sanren.ac.za/pub/config/sanren_mesh_2019.json?format=psconfig"
   }
]

 

/var/log/perfsonar/psconfig-pscheduler-agent-tasks.log is empty

/var/log/perfsonar/psconfig-pscheduler-agent-transactions.log is empty

/var/log/perfsonar/psconfig-pscheduler-agent.log has the following error:
2022/06/07 07:46:27 ERROR pid=387 prog=main::__ANON__ line=131 msg=Died: /etc/perfsonar/psconfig/pscheduler.d watcher creation failed at /usr/lib/perfsonar/bin/psconfig_pscheduler_agent line 160

No errors in /var/log/messages

 

DNS inside the container is working fine and it can resolve perf-pwa.sanren.ac.za. 

Only forward DNS is configured for the container and it's working fine

[root@ps-100-100g /]# host ps-100-100g.perfsonar.ac.za
ps-100-100g.perfsonar.ac.za has address 155.232.40.194

 

ntpd is running on the docker host. 

lsregistration is working fine

The mesh config file is built on a PWA server. All my other servers + Maddash are happy with the mesh config file

I can download the meshconfig with "psconfig translate http://perf-pwa.sanren.ac.za/pub/config/sanren_mesh_2019.json?format=psconfig" and it looks fine.

 

My server setup:

Ubuntu 20.04.4, with a dual 100g Ethernet interface card

DNS + ntpd is running on the host. 

The container uses MACVLAN networking, on its own dedicated Ethernet adapter and it starts up using docker-compose

The testpoint image is set to image: perfsonar/testpoint:latest

The timezone is configured inside docker-compose.yml

 

Any ideas on how to debug this ?

 

Regards

Johann
