No. the node/pid list will not necessarily be in the same order on all nodes. Even though the join/leave mechanism is strictly ordered, when new nodes are added to a group they get their list sent to them from other nodes and this will arrive after they have added themselves. > I'm looking for a way to pick a single member of the cluster to respond > to config changes - e.g. to mcast cluster-wide information for new > members. The usual way of doing this is to pick the lowest node ID of all nodes in the group. -- Chrissie _______________________________________________ Openais mailing list [email protected] https://lists.linux-foundation.org/mailman/listinfo/openais
