Description Pedro Amoedo 2020-03-31 21:07:24 UTC
Description of problem:

An OCP 4.3 cluster was freshly installed over OpenStack 13 using IPI method. 
After that, certificates for API and *.apps were installed according to the documentation.
No other noticeable configuration actions were performed.

Operator Package Server (0.13.0) is in 'Cannot update' status.
Event log contains multiple installation attempts and events "APIServices not installed". 
At the same time, Package Server appears to be fully operational. Nothing suspicious in the pods, operator manifests properly loaded and rendered from all sources.

OLM pod log has multiple entries:

```time="2020-03-21T02:06:49Z" level=info msg="checking packageserver"
time="2020-03-21T02:06:49Z" level=info msg="Labels updated!" labels="olm.api.4bca9f23e412d79d=provided,olm.clusteroperator.name=operator-lifecycle-manager-packageserver,olm.version=0.13.0"

`v1-packages-operators-coreos-com` service has multiple ownerReferences with identical uid, the number grows over time.

Version-Release number of selected component (if applicable):

OCP 4.3.8
Package Server (0.13.0)

How reproducible:
Unknown (fresh install)

Steps to Reproduce:
1. OSP 13
2. OCP 4.3.x IPI

Actual results:

Strange operator behavior.

Expected results:

Avoid those error messages if the operator is properly running.

Additional info:

There is a related KCS[1] that states the following:

The Package Server Operator is applied as a ClusterServiceVersion that Operator Lifecycle Manager does install directly without a Subscription or CatalogSource. The application of this ClusterServiceVersion is handled by ClusterVersionOperator, so upgrades to it occur with regular Red Hat OpenShift Container Platform - update and won't be an issue.

Comment 14 Fran Kemp 2020-05-19 18:14:40 UTC
Having a very similar situation to this on an OpenShift cluster installed using IPI on the IBM Cloud last week.

OCP 4.3.12 was installed initially - since upgraded to 4.3.18 and seems to be operating normally otherwise.

There is 1 thing I'm seeing that is not listed in this bug:  The Control Plane is listed as "Not Available" on the Administrator Dashboard.
Is that caused by this bug also or do I have another problem?

>  The Control Plane is listed as "Not Available" on the Administrator Dashboard.

That indicates a more fundamental problem - in general, cluster components being unavailable (discovery in particular) can cause packageserver to report unhealthy, because OLM uses discovery to confirm the health of the apiservice.

Given that the objects in the current report show that the packageserver is healthy and we haven't heard back, I'm going to close this again. Please re-open with additional information describing the failure if one still exists (it is not apparent that there is an error from the current report).

Comment 33 Jian Zhang 2020-11-11 06:34:28 UTC
I find the fixed PR only for the packageserver ownerReferences issue. And, only one ownerReferences uid, LGTM, I'm going to verify this 4.7 bug. 

1, Create the 4.7 cluster
[root@preserve-olm-env data]# oc get clusterversion
NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.7.0-0.nightly-2020-11-11-033756   True        False         78m     Cluster version is 4.7.0-0.nightly-2020-11-11-033756
[root@preserve-olm-env data]# oc adm release info registry.svc.ci.openshift.org/ocp/release:4.7.0-0.nightly-2020-11-11-033756 --commits|grep lifecycle
  operator-lifecycle-manager                     https://github.com/operator-framework/operator-lifecycle-manager            161c86b215ceae325d7bf8f7f351406a0303ca27

2, Check the packageserver service
[root@preserve-olm-env data]# oc api-resources|grep packages
packagemanifests                                       packages.operators.coreos.com         true         PackageManifest

[root@preserve-olm-env data]# oc get service packageserver-service -n openshift-operator-lifecycle-manager -o yaml
apiVersion: v1
kind: Service
  - apiVersion: operators.coreos.com/v1alpha1
    blockOwnerDeletion: false
    controller: false
    kind: ClusterServiceVersion
    name: packageserver
    uid: 443dba6c-1561-4e30-8faa-f4c0fdd4b9d3
  resourceVersion: "8082"
  selfLink: /api/v1/namespaces/openshift-operator-lifecycle-manager/services/packageserver-service
  uid: 48e27560-80b7-4116-a6d3-dac24cce9bcc

[root@preserve-olm-env data]# oc get csv -n openshift-operator-lifecycle-manager packageserver -o yaml
apiVersion: operators.coreos.com/v1alpha1

  name: packageserver
  namespace: openshift-operator-lifecycle-manager
  resourceVersion: "59704"

  uid: 443dba6c-1561-4e30-8faa-f4c0fdd4b9d3

3, The upgrade to 4.7 from 4.6 works well. I couldn't reproduce the origin issue. Please let me if I missed something, thanks!
