When two are specified, the one with 'ringnumber' of '0' # is the primary ring and the second with 'ringnumber' of '1' is the # backup ring. interface { # Increment the ring number for each 'interface' directive. ringnumber: 0 # This must match the subnet of this interface. The final octal # must be '0'. In this case, this directive will bind to the # interface on the 192.168.1.0/24 subnet, so this should be set # to '192.168.1.0'. This can be an IPv6 address, however, you # will be required to set the 'nodeid' in the 'totem' directive # above. Further, there will be no automatic interface # selection within a specified subnet as there is with IPv4. # In this case, the primary ring will be on the interface with # IPs on the 10.0.0.0/24 network (ie: eth1). bindnetaddr: 10.0.0.0 # This is the multicast address used by OpenAIS. Avoid the # '224.0.0.0/8' range as that is used for configuration. If you # use an IPv6 address, be sure to specify a 'nodeid' in the # 'totem' directive above. mcastaddr: 226.94.1.1 # This is the UDP port used with the multicast address above. mcastport: 5405 } # This is a second optional, redundant interface directive. If you use # two 'interface' directives, be sure to review the four 'rrp_*' # variables. # Note that two is the maximum number of interface directives. interface { # Increment the ring number for each 'interface' directive. ringnumber: 1 # In this case, the backup ring will be on the interface with # IPs on the 192.168.1.0/24 network (ie: eth0). bindnetaddr: 192.168.1.0 # MADI: Does this have to be different? How much different? # Can I just use a different port? mcastaddr: 227.94.1.1 # MADI: If this is different, can 'mcastaddr' be the same? mcastport: 5406 } ------------------------------------ Hope this helps. :) -- Digimer E-Mail: digimer@xxxxxxxxxxx AN!Whitepapers: http://alteeve.com Node Assassin: http://nodeassassin.org -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
