You could set :primary => false on any non primary servers and change
your run mycommand2 to :only => { :primary => false }
Keep in mind :primary must be set to false not omitted from the :role
specification.
If your use case supports it you may be able to:
> run "my command 2", :roles => :app
> run "my command 1", :roles => :app, :once => true
As long as c1 will overwrite the state of c2 and it's not critical
which server c1 is ran on; just that it's ran once.
