You can't do this directly. Even if you were to use storeconfigs to get at facts about other nodes, all that would tell you is that the database service was running the last time puppet ran on that node. Besides, the important thing to know, even more important than whether the service is running on the dbnode, is whether you can usefully connect to the service from your appserver node. Even if the service is running, other things might prevent that. I think the best approach would be to have a test that runs on your appservernode, connects to your postgres server and does a simple status check. You could do this as a custom fact, so that it set a variable like $dbservice to true or false, or you could do it as an exec. But can your application server really not cope with the database service not being available? Can they not present a useful error message if the database is broken? How will you cope if the database service dies once your appserver has started? -- Bruce If the universe were simple enough to be understood, we would be too simple to understand it. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
