  Result: two lists:


  		





  95
  95
  
    
    - list of node names with bad data returned (unreachable, etc.)


  		





  
  96
  
    
    - dist of node names with broken volume groups (values: error msg)


  		





  96
  97
  
    
    - list of instances with degraded disks (that should be activated)


  		





  
  98
  
    
    - dict of instances with missing logical volumes (values: (node, vol)


  		





  
  99
  
    
      pairs with details about the missing volumes)

  In normal operation, both lists should be empty. A non-empty


  		





  99
  
  
    
  instance list is still ok (errors were fixed) but non-empty node


  		





  100
  
  
    
  list means some node is down, and probably there are unfixable drbd

  errors.

  In normal operation, all lists should be empty. A non-empty instance


  		





  
  102
  
    
  list (3rd element of the result) is still ok (errors were fixed) but


  		





  
  103
  
    
  non-empty node list means some node is down, and probably there are


  		





  
  104
  
    
  unfixable drbd errors.

  Note that only instances that are drbd-based are taken into

  consideration. This might need to be revisited in the future.
