Yes, at the moment we stop it first with the stop function and then execute the RA with the start parameter in the background returning OCF_SUCCESS. Then there are some stamp files containing the current time in unix seconds to prevent another start while asynchonely demoting. I am experimenting right now with just using the stop function. It works at least for three failover scenarios: - poweroff the master - reboot the master - crm node standby / crm node online the master Next I need to test migrate, I think the reason for the complex demote fake was a problem with migrate. best regards Waldemar _______________________________________________ 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
