➢ Hello everyone. ➢ We are implementing a 2 node HA cluster, using OpenAIS 0.80.3 on SLES 11 HAE. We have found out our service provider is using Cisco switches which don’t support IP multicasting.
➢ We have checked and can’t see any multicast traffic running on the LAN, whereas on the virtual test development environment we have, it is. ➢ The odd thing is – the cluster is working fine. Can anyone tell me how it is communicating / establishing quorum etc. without multicast working? If it has found another communication route what are the reliability and performance implications? ➢ Regards, ➢ Darren Mansell From extra investigation it seems the 2 nodes are talking using unicast on UDP 5150. Does this mean we can't use any more than 2 nodes with Cisco switches? Thanks Darren _______________________________________________ Openais mailing list [email protected] https://lists.linux-foundation.org/mailman/listinfo/openais
