      WMCO was missing a field required for draining nodes with emptydir volumes attached. As a consequence, customers that had nodes with emptydir data volumes would see the following error in the logs: 'cannot delete Pods with local storage'. The necessary field was added to the node drain helper struct in WMCO and as a result, customers are able to drain nodes with emptydir volumes attached.

      Description of problem:

      When performing an upgrade to WMCO 7.1.1, nodes did not correctly drain pods with local data and drains were applied spontaneously rather than in rolling fasion.

      Version-Release number of selected component (if applicable):

      7.1.1

      How reproducible:

      Consistently

      Steps to Reproduce:

      1. Upgrade WMCO

      Actual results:

      Nodes drains do not handle local data pods well and drains do not appear to happen in rolling fashion.

      Expected results:

      Node drains would account for local data and operate in rolling fasion.
