Bug 2015408

Created attachment 1834512 [details]
terminal log

Description of problem (please be detailed as possible and provide log
snippests):
============================================================================
This bug is in continuation of Bug 1934625 for the following issue which was not fixed in 4.9. Talked to dev and we proposed to raise a bug and then have a open discussion on this bug with other stakeholders.

Initially it was thought that from ODF 4.9, Noobaa would be independent of the storagecluster resource but that is change is not yet part of 4.9(not sure if planned for 4.10)

Based on that, until a storagecluster is created, do we really need  attempts at collecting following noobaa related stuffs (If yes, ignore this comment)

Does this issue impact your ability to continue to work with the product
(please explain in detail what is the user impact)?
=====================================================================
No

Is there any workaround available to the best of your knowledge?
==============================================================
NA

Rate from 1 - 5 the complexity of the scenario you performed that caused this
bug (1 - very simple, 5 - very complex)?
==================================================================================
2

Can this issue reproducible?
===============================
Always in all versions

Can this issue reproduce from the UI?
==========================================
NA

If this is a regression, please provide more details to justify this:
========================================================================
No, present since the start

Steps to Reproduce:
=====================
1. Install OCS operator. Do not install Storagecluster
2. Initiate a must-gather collection
oc adm must-gather --image=quay.io/rhceph-dev/ocs-must-gather:latest-4.8 |tee terminal-must-gather

oc adm must-gather --image=quay.io/rhceph-dev/ocs-must-gather:latest-4.9 |tee terminal-must-gather-49

Similar observation seen in another reproducer:

1. Install OCS operator and create storagecluster
2. Delete storagecluster and follow uninstall steps(remove OCS completely, along with OCS node label)



Actual results:
====================
Noobaa resources are attempted to be collected which shows in terminal logs

Expected results:
=====================
if storagecluster is not present, and noobaa depends on storagecluster, then we should skip collecting the MCG details.

But we also need to discuss on trade-off between fixing it for current release or we are OK to have it and not affect the existing working code.
