I'm guessing the issue is that the set already exists; "order set"
creates a new one. I don't think there is a single command to modify an
existing set. You could delete the existing one then add the new one
(preferably using -f with an external file to make the changes atomic).
Or, you could use "pcs cluster edit" and modify the XML interactively.
