These are complementary, not opposing, technologies. DRBD = block-level disk replication (think 'RAID 1 over a network') Corosync = Cluster membership, ordered messaging, etc. Pacemaker = Cluster resource management. That is, what runs where on the cluster depending on the current membership. So the short answer to you question is; All three. The long answer depends entirely on what you are trying to do. -- Digimer Papers and Projects: https://alteeve.com _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
