Dell CSI Driver deploy on OpenShift

Hello,

In the infrastructure of our company we use OpenShift Container Platform version 4.6. We have a DELL CSI driver version 1.4.0 installed on it and use CSI PowerScale to manage volumes on Isilon storage. The CSI Driver is  installed as an operator, not with a Helm chart.

This CSI operator is trying to run "isilon-nodes" pods on all worker nodes in the cluster, as this is how the Daemon set is configured. However, we want to run pods only on certain nodes labeled "worker", we do not run custom applications on other workers, labeled as "infra node" so we do not need them to use storage.

We tried to solve the problem by adding "nodeSelector" in CSI Operator YAML, node specs section :

nodeSelector:

  node-role.kubernetes.io/worker: ''

This seems to have helped and now running pods only on the worker nodes we wanted.

We noticed, however, that the status of Dell CSI PowerScale, CSIIsilon Details - > section NodeSelector for driver nodes is marked as "Unsupported"

Since this is a preparation for our production environment we worry about this text mark " Unsupported" will may lead to problems in the future. 

Our request is to help us understand if the configuration we made ( adding node selector) is supported and if not, to help us configure the driver correctly.

Best regards,

Emiliyan Mladenov
