You may need the new cluster-ipc-limit cluster property available in Pacemaker 1.1.17. The recommended value for large clusters is the number of nodes times the number of resources. The default is 500. If you see "Evicting client" log messages after cleanups or node joins, you definitely need this. I'm not aware of any other tuning needed, but let us know if you encounter anything else. > > Best Regards. > ····················································· > Roberto Muñoz > > > > P Antes de imprimir, piensa en el MEDIO AMBIENTE > AVISO LEGAL/DISCLAIMER -- Ken Gaillot <[email protected]> _______________________________________________ Users mailing list: [email protected] http://lists.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
