  • 1.  topology-merge and topology-search pods in CrashLoopBackoff state

    Posted 04/02/21 02:45 PM
    Watson AIOps 2.0 Event Manager installed on OpenShift 4.7.

    The topology-search and topology-merge pods keep restarting and can be seen in a CrashLoopBackoff state. Why I found this is when I go to Topology from NOI, I get an error:

    (Critical Failed to connect to the Search Service. The application configuration may be incorrect, or the ASM backend services may not be running.)

    That's why I looked at the status of the pods. These two pods have restarted 47 times since I installed NOI 2 hours ago.

    Any pointers? Running 'oc describe pod <pod_name>' doesn't show any errors. There is a warning that neither pod can get to the healtcheck URL, but that's the only error.

    Hi Frank,

    usually its because the *topology-topology* pod is not started or unavailable..

    anything in the logs ?

    Thanks for the reply, Mario. It turns out that the OpenShift version is the problem. I have reinstalled at OpenShift 4.6.17 and now topology search works (and the topology-search pod stays alive). However, it looks like I should have installed OpenShift 4.6.16 to avoid another problem. Thanks again for the reply.

    OpenShift 4.6.16 doesn't work as well as 4.6.17. Topology search fails (and the pod is in CrashLoopBackoff). Is there a known good version of OpenShift that I can install on that will allow all the pods to run correctly when run on vSphere 6.7 with Installer Provisioned Infrastructure?

    So far I've tried the following OpenShift versions:

    4.6.16 - topology search doesn't work (there's no healthcron pod, so I'm assuming it worked)
    4.6.17 - topology search works, but the healthcron pod can't be created
    4.6.23 - too unstable to even install Watson AI Ops
    4.7- topology search doesn't work
