is it necessary "cluster.ocs.openshift.io/openshift-storage" label on nodes ?

[HasibMahdi]

Is it really needed to add lables on nodes "cluster.ocs.openshift.io/openshift-storage" before installing localstorage and OCS/ODF operator ?

Observing - cluster.ocs.openshift.io/openshift-storage label auto came on nodes after OCS/ODF operator installation..

@HasibMahdi @Sailas As far as I know yes it is required.

For node based subscription - and make nodes as Infra node -> it is necessary to mention the labels. Specially on production grade system. 

For Labs on DO370 - it automatically get fixed on those 3 nodes while installing OCS/ODF operator (As those nodes were using as Infra nodes).
