Comment 4 RAJAT SINGH 2021-06-02 03:01:43 UTC 
Well, the reason why this is happening is because, we have not defined any tolerations on the helper pod and as a result, the pod will repel from the nodes which are tainted even if they are OCS(labelled) nodes, it will only work on those nodes which are OCS labelled AND not tainted, like in step 3 you described, once you uncordon the nodes, it collects all the logs, I am hoping that they were not tainted in that case.

So we have to add toleration for all the taints that OCS has and could be applied on all the worker nodes.
Comment 5 RAJAT SINGH 2021-06-02 06:40:07 UTC 
I have added the toleration for the mentioned taint in the BZ, so if there are any more taints, please let us know here.
