Hi Richard, > What is the address specified in the stacked-on-top-of section? The good reading is the DRBD Users Guide at www.drbd.org. There is a figure about concept of three-way replication in PartI "Introduction to DRBD" (http://www.drbd.org/users-guide-emb/s-three-way-repl.html). Figure 2.1 "DRBD resource stacking" shows that "stacked-on-top-of" side (the upper layer) DRBD must runs on top of PRIMARY lower layer DRBD. Therefore the IP address of "stacked-on-top-of" section should be one of floating address (virtual address) controlled by cluster manager. Please also refer to section "Creating a three-node setup" in Part III (http://www.drbd.org/users-guide-emb/s-three-nodes.html). I usually use eth1 for lower layer DRBD and eth0 for upper layer DRBD as well as service. For example, when using example configuration in Part III, 10.0.0.0/24 belongs to eth1. The eth0 address of alice and bob would be 192.168.42.100 and 192.168.42.101, respectively. My cluster manager should assign 192.168.42.1 to eth0:0 of active node. Hope this helps you.
