Hi, I think the appropriate constraint in this case is a colocation. A group implies other constraints on the resources as well, for example if one of the resources fails, other resources appearing after it in the group will also be stopped. A colocation constraints only says that the resources should be placed on a particular node. However, if, for example, the Firewall depends on the VIP being started before it starts, you will need either an order constraint as well, or to use a group. > > Thanx! > > > -- > !!!!! > ( o o ) > --------------oOO----(_)----OOo-------------- > Luc Paulin > email: paulinster(at)gmail.com > Skype: paulinster -- // Kristoffer Grönlund // kgronl...@suse.com _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
