    • On MCP with higher maxUnavailable than unavailable nodes, cordoned nodes were mistakenly selected as an update candidate, depending on the order of the node list. This fix will always ensure cordoned nodes will not be queued for an update.

      Description of problem:

      Node has been cordoned manually.After several days, machine-config-controller uncordoned the same node after rendering a new machine-config.

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

          4.13

      Actual results:

      The mco rolled out and the node was uncordoned by the mco

      Expected results:

       MCO treat unscedhulable node as not ready for performing update. Also, it may halt update on other nodes  in the pool based on what maxUnavailable is set for that pool
