Creates a new group with the given name. The node group will be


  		





  32
  
  
    
initially empty.


  		





  
  32
  
    
initially empty; to add nodes to it, use ``gnt-group assign-nodes``.

The ``--node-parameters`` option allows you to set default node


  		





  35

parameters for nodes in the group. Please see **ganeti**(7) for more

    (this is the default). Note that prioritization among groups in this


  		





  53
  53
  
    
    state will be deferred to the iallocator plugin that's being used.

Assigns one or more nodes to the specified group, moving them from their

original group (or groups).

By default, this command will refuse to proceed if the move would split

between groups any instance that was not previously split (a split


  		





  
  67
  
    
instance is an instance with a mirrored disk template, e.g. DRBD, that


  		





  
  68
  
    
has the primary and secondary nodes in different node groups). You can


  		





  
  69
  
    
force the operation with ``--force``.
