Executes a command on all nodes. If the option ``-n`` is not given,

the command will be executed on all nodes, otherwise it will be

The ``-g`` option can be used to run a command only on a specific node


  		





  
  50
  
    
group, e.g.::


  		





  
  51
  
    

  		





  
  52
  
    
    # gnt-cluster command -g default date

The command is executed serially on the selected nodes. If the


  		





  50
  55
  
    
master node is present in the list, the command will be executed


  		





  51
  56
  
    
last on the master. Regarding the other nodes, the execution order

Copies a file to all or to some nodes. The argument specifies the


  		





  73
  79
  
    
source file (on the current system), the ``-n`` argument specifies


  		





  74
  80
  
    
the target node, or nodes if the option is given multiple times. If


  		





  75
  
  
    
``-n`` is not given at all, the file will be copied to all nodes.


  		





  
  81
  
    
``-n`` is not given at all, the file will be copied to all nodes. The


  		





  
  82
  
    
``-g`` option can be used to only select nodes in a specific node group.

  83
  
    
Passing the ``--use-replication-network`` option will cause the


  		





  77
  84
  
    
copy to be done over the replication network (only matters if the


  		





  78
  85
  
    
primary/secondary IPs are different). Example::
