I'm wondering if maybe you were using the term "group" generically? The other responses were referring to Pacemaker's explicit group syntax. By default, all resources are independent of each other, and can be started in any order and on any node. To tell the cluster that some resources are related, you can use either constraints or groups. Groups are effectively a shorthand for the most common constraint scenario: a series of resources need to be started in order, kept together on the same node, and stopped in the reverse order. How you set up a group depends on what tools you're using; for example, in pcs, it would be something like: pcs resource create (...first resource parameters...) --group mygroup pcs resource create (...second resource parameters...) --group mygroup etc. Or you can add existing resources to a group with the "pcs group add" command. _______________________________________________ Users mailing list: Users@clusterlabs.org http://clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
