Remove nodes from a node group

To remove dynamically-assigned nodes from a node group, edit or delete the applicable rule. To remove statically-assigned nodes from a node group, unpin them from the group.

Note: When a node no longer matches the rules of a node group, it is no longer classified with the classes assigned in that node group. However, the resources that were installed by those classes are not removed from the node. For example, if a node group has the apache class that installs the Apache package on matching nodes, the Apache package is not removed from the node even when the node no longer matches the node group rules.
  1. In the console, click Classification, and select a node group.
  2. On the Rules tab, select the option appropriate for the type of node.

    • Dynamically-assigned nodes — In the Fact table, click Remove to remove an individual rule, or click Remove all rules to delete all rules for the node group.

    • Statically-assigned nodes — In the Certname table, click Unpin to unpin an individual node, or click Unpin all pinned nodes to unpin all nodes from the node group.
      Tip: To unpin a node from all groups it’s pinned to, use the unpin-from-all command endpoint.
