Looks good but small typo on step 3, replace csi-plugis with csi-cephfsplugin-* and csi-rbdplugin-*. 
It would be good to change step 3 as Verify the csi-cephfsplugin-* and csi-rbdplugin-* pods are running on the tainted nodes(in above e.g, it is infra). And we can split this as verification steps.

And also it is better to add a note after display config that in above example shown is of configmap when the nodes are tainted with these key/values

Comment 8 akarsha 2020-04-06 11:28:22 UTC

Followed doc [1] and was able to see the csi-plugins on tainted nodes. So moving the bz to verified.

Procedure:
----------

1. Had one node tainted as infra.

$ oc adm taint nodes ip-10-0-131-78.us-east-2.compute.internal  nodetype=infra:NoSchedule
node/ip-10-0-131-78.us-east-2.compute.internal tainted

2. Created configmap rook-ceph-operator-config.
$ oc create -f rook-ceph-operator-config.yaml
configmap/rook-ceph-operator-config created

3. Restarted rook-ceph-operator.
$ oc delete pod rook-ceph-operator-74c5c8d975-ckr9x -n openshift-storage
pod "rook-ceph-operator-74c5c8d975-ckr9x" deleted


Verification:
-------------

csi-cephfsplugin-* and csi-rbdplugin-* pods are running on the tainted nodes

$ oc get pods -n openshift-storage -o wide| grep ip-10-0-131-78.us-east-2.compute.internal
csi-cephfsplugin-gkklt                                            3/3     Running     0          84s   10.0.131.78    ip-10-0-131-78.us-east-2.compute.internal    <none>           <none>
csi-rbdplugin-mfq4d                                               3/3     Running     0          74s   10.0.131.78    ip-10-0-131-78.us-east-2.compute.internal    <none>           <none>
