Hi Andrew, can you tell me what the attribute #uname is holding? Is it the node-name or the 'uname -n' of the node? (I justt read http://clusterlabs.org/doc/en-US/Pacemaker/1.1-plugin/html-single/Pacemaker_ Explained/index.html#_which_resource_instance_is_promoted)
Is there an attribute like '#node'or '#nodename'? Best regards Andreas Mock -----Ursprüngliche Nachricht----- Von: Andrew Beekhof [mailto:and...@beekhof.net] Gesendet: Mittwoch, 12.
