    Description

      Description of problem:

      The [Jira:"Network / ovn-kubernetes"] monitor test pod-network-avalibility setup test is a frequent offender in the OpenStack CSI jobs. We're seeing it fail on 4.14 up to 4.16.

      Example of failed job.
      Example of successful job.

      It seems like the 1 min timeout is too short and does not give enough time for the pods backing the service to come up.

      Additional info:

      Please fill in the following template while reporting a bug and provide as much relevant information as possible. Doing so will give us the best chance to find a prompt resolution.

      Affected Platforms:

      Is it an

      1. internal CI failure
      2. customer issue / SD
      3. internal RedHat testing failure

      If it is an internal RedHat testing failure:

      • Please share a kubeconfig or creds to a live cluster for the assignee to debug/troubleshoot along with reproducer steps (specially if it's a telco use case like ICNI, secondary bridges or BM+kubevirt).

      If it is a CI failure:

      • Did it happen in different CI lanes? If so please provide links to multiple failures with the same error instance
      • Did it happen in both sdn and ovn jobs? If so please provide links to multiple failures with the same error instance
      • Did it happen in other platforms (e.g. aws, azure, gcp, baremetal etc) ? If so please provide links to multiple failures with the same error instance
      • When did the failure start happening? Please provide the UTC timestamp of the networking outage window from a sample failure run
      • If it's a connectivity issue,
      • What is the srcNode, srcIP and srcNamespace and srcPodName?
      • What is the dstNode, dstIP and dstNamespace and dstPodName?
      • What is the traffic path? (examples: pod2pod? pod2external?, pod2svc? pod2Node? etc)

      If it is a customer / SD issue:

      • Provide enough information in the bug description that Engineering doesn't need to read the entire case history.
      • Don't presume that Engineering has access to Salesforce.
      • Please provide must-gather and sos-report with an exact link to the comment in the support case with the attachment. The format should be: https://access.redhat.com/support/cases/#/case/<case number>/discussion?attachmentId=<attachment id>
      • Describe what each attachment is intended to demonstrate (failed pods, log errors, OVS issues, etc).
      • Referring to the attached must-gather, sosreport or other attachment, please provide the following details:
        • If the issue is in a customer namespace then provide a namespace inspect.
        • If it is a connectivity issue:
          • What is the srcNode, srcNamespace, srcPodName and srcPodIP?
          • What is the dstNode, dstNamespace, dstPodName and dstPodIP?
          • What is the traffic path? (examples: pod2pod? pod2external?, pod2svc? pod2Node? etc)
          • Please provide the UTC timestamp networking outage window from must-gather
          • Please provide tcpdump pcaps taken during the outage filtered based on the above provided src/dst IPs
        • If it is not a connectivity issue:
          • Describe the steps taken so far to analyze the logs from networking components (cluster-network-operator, OVNK, SDN, openvswitch, ovs-configure etc) and the actual component where the issue was seen based on the attached must-gather. Please attach snippets of relevant logs around the window when problem has happened if any.
      • For OCPBUGS in which the issue has been identified, label with "sbr-triaged"
      • For OCPBUGS in which the issue has not been identified and needs Engineering help for root cause, labels with "sbr-untriaged"
      • Note: bugs that do not meet these minimum standards will be closed with label "SDN-Jira-template"
