You can set maintenance-mode using:

  pcs property set maintenance-mode=true

You can read about "maintenance-mode" cluster attribute and "maintenance" node
attribute in chapters:


I would bet the difference is that "maintenance-mode" applies to all nodes in
one single action. Using 'pcs node maintenance --all', each pcsd daemon apply
the local node maintenance independently. 

With the later, I suppose you might have some lag between nodes to actually
start the maintenance, depending on external factors. Moreover, you can
start/exit the maintenance mode independently on each nodes.
