perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi,

Looking through some of the tasks at "https://perfsonar2.ndsu.nodak.edu/pscheduler/tasks?expanded&pretty", the ones I don’t see displayed seem to have a mismatch of IPv4 and IPv6 addresses (e.g. source is an explicit IPv4 address and dest is an IPv6 address), or they have one side defined as an IPv6 address but have the ipv4-only flag set. Were all the tests defined through the GUI? Could you send me /etc/perfsonar/meshconfig-agent-tasks.conf?

Thanks,

Andy

We have two perfsonar boxes and after the automatic upgrade to 4.0 some graphs stopped updating.

It looks like the common variable for the graphs that do not update is that perfsonar lists the IPv6 address under the host name.

I verified that I can run the throughput tests manually over IPv6 with the pscheduler command.

I do see lots of these error messages but haven’t verified that they are related to the problem.

These are our two hosts that exhibit the problem.

Deleting the tests and adding them back with IPv4 set does not seem to result in working graphs either.


I also noticed the same problem on ps-border1-pt.lbl.gov to sites nersc-pt1-v6.es.net and bost-pt1-v6.es.net and sent email to the admin there and received a reply that they will add it to their list of issues to look into.
