direct links of old sources may well be a few messages off.

replying to whole list...
Actually I only have one resource, named "twovol"  composed by two
volumes and rate definition is inside resource itself; my drbd.conf
for this resource (only for initial testing of multivolume, to be
refined in general components), made up like this:

resource "twovol" {

  disk {
    on-io-error detach;

  volume 0 {
    device  minor 0;
    disk  /dev/vdb1;
    meta-disk  internal;

  volume 1 {
    device  minor 1;
    disk  /dev/vdc1;
    meta-disk  internal;

  syncer {
    rate 10M;
    verify-alg crc32c;
