Hi Kishore The event service is a part of openais (I am not particualy familar with it). But I can't find any special configuration options to it. For general service howto's: Have a look in corosync/README.devmap and http://www.corosync.org/doku.php?id=dev:plugin_cluster_services Regards Angus > > Thanks and Regards, > - Kishore > _______________________________________________ > Openais mailing list > Openais@lists.linux-foundation.org > https://lists.linux-foundation.org/mailman/listinfo/openais _______________________________________________ Openais mailing list Openais@lists.linux-foundation.org https://lists.linux-foundation.org/mailman/listinfo/openais
