Let me explain what made me confused. If you have:
order sample_order 1 2 3 colocation sample_colo inf: 3 2 1 it works ok as you say. If you have: order sample_order 1 2 3 colocation sample_colo inf: 1 2 3 it doesn't work at all! What order do you infer from last commands? My answer always was: Order statement will define the order so it is: 1,2,3. If colocation had any order it would be overwritten. But it seems to happen that the way it works is: Colocation will define the order so it is: 3,2,1: If order had any order defined it is overwritten. ----- Mensaje original ----- > De: "Jake Smith" <jsm...@argotec.com> > Para: "The Pacemaker cluster resource manager" > <pacemaker@oss.clusterlabs.org> > Enviados: Martes, 21 de Agosto 2012 15:59:54 > Asunto: Re: [Pacemaker] Help on setting order of resources > Adrian, > A few more comments below to maybe make it clearer... > > ----- Original Message ----- > > > De: "Adrian Gibanel" <adrian.giba...@btactic.com> > > > > > Para: "The Pacemaker cluster resource manager" > > > <pacemaker@oss.clusterlabs.org> > > > > > Enviados: Domingo, 19 de Agosto 2012 10:27:34 > > > > > Asunto: Re: [Pacemaker] Help on setting order of resources > > > > > Now that I'm reading about that it makes sense.
