This is a real pain and a showstopper. When you have 3 or more nodes in a Linux-HA cluster, DRBD requires that drbd volumes be declared on ALL hosts, although DRBD prevents the user from declaring a DRBD volume on more than 2 nodes in that cluster, requesting the user to upgrade to DRBD+. Nevertheless, even though DRBD+ would allow you to define a DRBD volume on more than 2 nodes, it still doesn't fix the issue that all DRBD volumes in a HA cluster require to have a declaration entry on every node of that cluster. This hardly makes any sense in, say a 8 node cluster with 25 drbd volumes, because I don't want/need each of all 25 DRBD volumes to be declared and have it's own listener process on all 8 nodes of that cluster, thus having 8 copies of each drbd volume. What I need is, within the "Free DRBD" license terms, simply use Linux-HA multi-node capability to it's full extend, without having DRBD castrating Linux-HA's mojo by restricting you to clusters with only 2 nodes. What I need is, withing the license terms of "Free DRBD", for DRBD to support drbd volumes configured on fewer nodes than the number of nodes in a Linux-HA cluster, enforcing for example the limit of 2 nodes per volume in "Free DRBD", but, allowing me to configure each drbd volume on *any* 2-node combination I choose, rather than on all nodes of the cluster.
