sudo salt --no-color 'worker40*' grains.get 'ip4_interfaces' shows

worker40.oqa.prg2.suse.org:
    ----------
    br1:
    erspan0:
    eth0:
    eth1:
    gre0:

I think there should be some entries populated

I ran 'salt 'worker29.oqa.prg2.suse.org' cp.get_template salt://openqa/openvswitch.sls /tmp/openvswitch' to check the content of our state which renders like this:

# Worker for GRE needs to have defined entry bridge_ip: <uplink_address_of_this_worker> in pillar data
/etc/wicked/scripts/gre_tunnel_preup.sh:



  file.managed:
    - user: root
    - group: root
    - mode: "0744"
    - makedirs: true
    - contents:
      - '#!/bin/sh'
      - action="$1"
      - bridge="$2"
      - '# enable STP for the multihost bridges'
      - ovs-vsctl set bridge $bridge stp_enable=false
      - ovs-vsctl set bridge $bridge rstp_enable=true
      - for gre_port in $(ovs-vsctl list-ifaces $bridge | grep gre) ; do ovs-vsctl --if-exists del-port $bridge $gre_port ; done
































      - 'ovs-vsctl --may-exist add-port $bridge gre8 -- set interface gre8 type=gre options:remote_ip=10.145.10.8 # worker35'

Yes. I was debugging that script by inserting commands like

{%- do salt.log.error('testing jinja logging') -%}

on OSD and executing salt commands against one worker and checking the minion log on that worker. That revealed that remote_bridge_interface for host worker40: [] so an empty list for remote_bridge_interface apparently? Then I called the command from #160646-2 and could confirm that there are no entries for IP address showing up. But after merging my workaround https://gitlab.suse.de/openqa/salt-pillars-openqa/-/merge_requests/814 which does not directly change any of those parameters still now again valid values show up. My current hypothesis is that during the last time the salt high state was applied the grains did not have valid data and our config was created with empty gre setup scripts.

Actually reading our jinja template to generate gre_tunnel_preup.sh and taking https://progress.opensuse.org/issues/160646#note-5 into consideration, I think that either our grains went missing on the hosts and therefore populated a wrong mine on each minion or the mine was producing wrong output.

After checking a possible place to fail, I came across a check introduced with: https://progress.opensuse.org/issues/130835#note-1 - I think without it we would have seen a failing pipeline. Anyhow, just removing it won't cut it because it describes a valid scenario to disable a salt-minion (blacklist its key on OSD) but have the data still present in the workerconf.sls

Could we please merge solution? I think thanks to limitation to one worker we have pending jobs for 3 days like https://openqa.suse.de/tests/14398639.

https://gitlab.suse.de/openqa/salt-states-openqa/-/merge_requests/1196 was merged, and we're monitoring the results now

I run a Statistical analysis

https://openqa.suse.de/tests/14517120

All jobs passed.
I see that @nicksinger has applied some changes but I am not sure how this solved the problem. Or whether was resolved by another ticket with some other resolution (for instance https://progress.opensuse.org/issues/161381).

I think most of the ACs are covered but I cant tell if Prevent the same and similar problems in the future is satisfied.
