This is a clone of https://bugzilla.redhat.com/show_bug.cgi?id=2106838 for backporting purposes

 
+++ This bug was initially created as a clone of
Bug #2015023
+++

Description of problem:
Tried to uninstall the operator and it worked. However, the operator custom resource doesn't gets deleted.
Strangely, it is getting recreated even after issuing "oc delete operator <name>"

Version-Release number of selected component (if applicable):
4.7.31

How reproducible:
100%

Steps to Reproduce:
1. Install any operator
2. Check operator resource
3. Uninstall the operator
4. Try to delete the "operator" resource.
5. List the operator resource. The operator resource will get recreated.

Actual results:
The operator resource is not getting removed even after deleting it.

Expected results:
After issuing "oc delete operator <name>", the operator resource should get removed.

Additional info:
Similar bug[1] was fix in 4.7.0 but looks like the issue is still there.

Hi Team

Let me know if you need any logs.

Sorry for the slow response!

@
dgautam@redhat.com
I'm going to need the status of the Operator resource after the deletion attempt is made. That status should show any remaining components. Without that info, I can only suspect that some cluster scoped resources still exist that reference the Operator – e.g. a CRD – since I have been unable to reproduce the issue myself.

A must-gather will help too.

Hi Nick

Must-gather is available in below google drive:

If required, we can try to reproduce the issue together.

Looking at `cluster-scoped-resources/operators.coreos.com/operators/cloud-native-postgresql.sandbox-kokj.yaml` in the must-gather shows that there are still resources related to the Operator on the cluster:

```

• apiVersion: rbac.authorization.k8s.io/v1
  kind: RoleBinding
  name: postgresql-operator-controller-manager-1-9-1-service-auth-reader
  namespace: kube-system

  reason: InitialNamesAccepted
  status: "True"
  type: Established
  kind: CustomResourceDefinition
  name: scheduledbackups.postgresql.k8s.enterprisedb.io
  ```

These must be deleted before the Operator resource can be.

I'm now fairly confident that this is not a bug. If you delete these resources then the Operator resource and it is still recreated, then please reopen this BZ.

Thanks!

Hi Nick

You got that absolutely right. The CRDs were not cleared due to which the operator resource was getting recreated.
This is not a bug.

Regards
Dhruv Gautam

— Additional comment from Nick Hale on 2021-12-14 15:57:11 UTC —

Looks like we're seeing cases with no components as well. I'm reopening this.

Just got out of a call with the related customer – they'll be posting a new must-gather soon.

Hi Dhruv,

Very sorry for the delayed response.

We have an upstream PR from an external contributor addressing this. I'm moving to get either get that in or create a patch myself.

Hopefully, there should be something merged upstream within the week – after that, I'll focus on getting it merged downstream, although I'm not sure if we can backport all the way to 4.7.z at this point. I'll follow up with the team and see what's possible.

I'll post my findings here later today.

— Additional comment from Nick Hale on 2022-02-10 15:26:05 UTC —

Current upstream PR:
https://github.com/operator-framework/operator-lifecycle-manager/pull/2582
— Additional comment from Nick Hale on 2022-02-10 16:16:50 UTC —

Okay, so it looks like we don't backport fixes for medium issues to 4.7.z. Have the customers upgraded to a newer version of OpenShift?

We can look into changing the severity if this issue is causing significant interruptions for users.

Here are the support phase dates for current OpenShift release:
https://access.redhat.com/support/policy/updates/openshift#dates
(that doc also has the phase SLAs as well)

— Additional comment from Dhruv Gautam on 2022-03-09 17:14:19 UTC —

Hi Nick

I understand your point about supportable phase and SLAs.

I would like to know:

• In which RHOCP version the fix will be made available ?
• Are there any tentative dates when the fix will be released ?

Dhruv,

An upstream fix for this – different than the one mentioned in my previous comment – has merged (see
https://github.com/operator-framework/operator-lifecycle-manager/pull/2697
).> - In which RHOCP version the fix will be made available ? If we can get the change synced to our downstream repository on time, it will be released in version 4.11.0.> - Are there any tentative dates when the fix will be released ?As of today, 4.11.0 is planned to go GA on July 13th 2022 (see
https://docs.google.com/spreadsheets/d/19bRYespPb-AvclkwkoizmJ6NZ54p9iFRn6DGD8Ugv2c/edit#gid=0

Hi Dhruv,

We've brought this change downstream on this PR:

I'll update this ticket to ON_QA

Hi,

My customer Telefonica is experiencing this problem (case linked) and requesting this backport to 4.8, as they are having this issue with multiple operators.

Could we have a backport schedule for this?

Thanks.

Best regards,
Raúl Fernández

Hello Team,

We have a customer with OCP 4.9.36 Baremetal and is facing this issue with Performance Addon Operator.
Easily reproducible: Installed the operator and Deleted it's resources:
~~~
$ oc delete csv performance-addon-operator.v4.8.8
$ oc delete ip install-flsns
$ oc delete sub performance-addon-operator
$ oc delete job.batch/77c159445752f625e1337c92dabd6cfdfc1eebcb7accbbfd5d1c7227656cec6 -n openshift-marketplace
$ oc delete configmap/77c159445752f625e1337c92dabd6cfdfc1eebcb7accbbfd5d1c7227656cec6 -n openshift-marketplace
$ oc get crd | grep performance
$ oc delete crd performanceprofiles.performance.openshift.io
$ oc scale deployment -n openshift-operator-lifecycle-manager olm-operator --replicas=0
$ oc delete operator performance-addon-operator.openshift-operators
$ oc scale deployment -n openshift-operator-lifecycle-manager olm-operator --replicas=1
$ oc get operator
NAME AGE
performance-addon-operator.openshift-operators 7m31s
~~~

The Operator still exists in CLI but when I checked the web console I couldn't find any operator there. We tried various other ways to delete but no luck.

Can we get an update in which version is this going to be fixed?

Hello Team,

Accounts team has reached out to EMT on this as the Customer is frustrated with the time being consumed without a fix. The Customer temperature is high and would request your intervention in getting a permanent fix or workaround at the earliest, to avoid the situation blowing up further.

Please find the Business impact as shared by the Accounts Team for your reference.

Business Impact - This issue has made the development functionality miss 2 sprint cycles of delivery for the customer. Customer cannot afford to miss delivery of yet another cycle and delay in delivery.

Thanks,

Himadri.

Hi,

Now that this BZ is in verified state, I think a back port to 4.10 is needed as this issue is affecting many customers. Is there any plan for it?
