Description

Some LTP tests trigger large amounts of kernel log messages and then upload journalctl logfile to OpenQA. In this example, shutdown_ltp-journalctl.txt log file contains 18MB of data and the upload took 111 seconds (upload speed: ~168KB/s, upload timeout: 100s).
https://openqa.suse.de/tests/16073659#step/shutdown_ltp/55

The PowerVM SUT (upload source) is nessberry-2, the OpenQA controller host (upload destination) is worker29.oqa.prg2.suse.org. What is the expected bandwidth between the machines?

Acceptance criteria

  • AC1: A sufficiently high bandwidth is ensured between usual OSD involved testing machines, e.g. ~1GBit/s

Suggestions

  • Follow and respond on https://sd.suse.com/servicedesk/customer/portal/1/SD-175581
  • Check bandwidth between various hosts, e.g. with iperf, and comment back in the SD ticket
    • And use -4 and -6 to check IPv4 vs. IPv6
  • Depending on how the problem can be reproduced, e.g. which hosts are affected, investigate/mitigate/solve the underlying issue, e.g. anything in the range from "just trigger a reboot to the HMC or switch" to work in a task force with IT to identify misbehaving systems severly impacting the available bandwidth
  • Also be aware about #133700 and shove it in the face of IT
  • Don't just bump timeouts here

hi, as suggested in https://suse.slack.com/archives/C02CANHLANP/p1734001300419849?thread_ts=1733757997.878699&cid=C02CANHLANP

I doubt we have the necessary observables accessible to us to help here. I suggest you start a discussion with IT who are responsible for the underlying network infrastructure. As we all know about the limitations of Jira SD tickets I suggest you create a ticket in https://progress.opensuse.org/projects/openqa-infrastructure/ , create an SD ticket and link back to that progress ticket

so this is the progress ticket. Do you plan to create the Jira SD ticket accordingly or how do you recommend to proceed?

we should handle the open point from SD ticket in https://sd.suse.com/servicedesk/customer/portal/1/SD-175581

Could you please check connectivity with the servers
in the same segments as nessberry and worker29.oqa.prg2.suse.org
Those servers are in different network segments and must check speeds without routers and firewalls.
Could you please check it?
If speed isn't acceptable we will ask Network team's help.

I've conducted the wanted tests and found no issues between several hosts:

Looks fine. The machines are in the same chassis so I tested with storage as well and archived ~1Gbit/s - so all good here. Moving on into the qe.prg2.suse.org-domain I used ada to verify the speed to worker29:

Again everything seems fine into and out over this network-segment-border. My last try was with the actual 2 systems:

I think it should be noted that nessberry-2 -> worker29 transfer over IPv6 is almost 1000 times slower than all the other speed tests:

Oh yes you're absolutely right. I will look into that one and try to add another commend in SD before they close it. Thanks for catching that!
