      * Previously, a machine config pool (MCP) with a higher `maxUnavailable` value than the amount of unavailable nodes would cause cordoned nodes to receive updates if they were in a certain position on the node list. With this release, a fix ensures that cordoned nodes are not added to a queue to receive updates. (link:https://issues.redhat.com/browse/OCPBUGS-37629[*OCPBUGS-37629*])

      This is a clone of issue OCPBUGS-33397. The following is the description of the original issue:
      —
      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
