perfSONAR User Q&A and Other Discussion

Hi Experts!

 

I’m a perfsonar newbie and installed the pS-Toolkit-4.0-CentOS7-FullInstall-x86_64-2017Apr17.iso on an ESXi VM behind a lab firewall and cannot get the pscheduler archiver to run.

 

/var/log/pscheduler/pscheduler.log constantly restarts with the below error “OperationalError: FATAL:  role "pscheduler" does not exist”.  More detail log below.

 

The follow updates to the CentOS7 were done to handle firewall issues:

 

1)      /etc/profile.d/proxy.sh                 !!! set http_proxy/https_proxy to allow “only” http/https traffic on ports 80/443 to go thru firewall

2)      /etc/resolv.conf                                               !!! updated for DNS servers

3)      /etc/sysconfig/network-scripts/ifcfg-eth0  !!! updated for static IP, Gateway

4)      /etc/ntp.conf                                    !!! updated to use a lab NTP server (ntp is correctly working)

 

 

Running the same ISO using a laptop VMware Player VM on a corporate network that does not have a strict firewall policy initially had similar failures, but manually running “systemctl start pscheduler-archiver” restarted the archiver successfully and everything started to work. When a perfsonar VM runs in our lab network behind the stricter FW, the above error always occurs and archiver never starts, even after issue the “systemctl restart  pscheduler-archiver” several times

 

Any help is appreciated!

 

 

Here’s the detailed pscheduler.log with “pscheduler debug on”.

I did follow the Trouble Shooting link without any luck : http://docs.perfsonar.net/troubleshooting_overview.html
