Description Jan Safranek 2020-08-03 14:50:43 UTC

Description of problem:

Steps to Reproduce:
1. Install a cluster on OpenStack with Manila (and get Manila CSI driver as part of it)

2. Check CSI driver pods:
   oc -n openshift-manila-csi-driver get pod -o wide

3. Create a pod on a master that uses PVC.

Actual results:

2. CSI driver pods run only on worker nodes

3. Masters can't use a PVC provided by the CSI driver

Expected results:
2. Even masters have both manila-csi-nodeplugin and manila-csi-nodeplugin driver pods
3. Masters can use a PVC provided by the CSI driver
