Groups of Compute Nodes can be removed from ClusterPack using /opt/clusterpack/bin/clgroup. The following example removes the node group "cae": % /opt/clusterpack/bin/clgroup -r cae Note that the above-mentioned command just removes the group; the nodes are still part of the cluster, and users can submit jobs to the nodes. For more details on the usage of clgroup, invoke the command: % man clgroup Back to Top 1.6.18 Add Nodes to a Cluster Group Compute Nodes can be added to existing groups in ClusterPack using /opt/clusterpack/bin/clgroup.
