The following code is what I was looking for. (I figured this out by
referencing the SUSE Linux Enterprise Server documentation, which has
the best examples using CRM):

# Activate Pacemaker's Distributed Lock Manager (DLM) and LVM locking
daemon (LVMLOCKD).
# DLM and LVMLOCKD must be activated together.
crm<<EOF.base
  configure
    property no-quorum-policy="ignore"
    rsc_defaults resource-stickiness="100"
    primitive controld ocf:pacemaker:controld \
      op monitor interval="60s" timeout="30s" \
      op start interval="0" timeout="90s" \
      op stop interval="0" timeout="100s"
    primitive lvmlockd lvmlockd \
      op monitor interval="60s" timeout="30s" \
      op start interval="0" timeout="90s" \
      op stop interval="0" timeout="100s"
    primitive LVM LVM-activate \
      params vgname=$(echo $LV_DRBD_PATH | cut -d "/" -f3)
vg_access_mode=lvmlockd activation_mode=shared \
      op monitor interval="60s" timeout="30s" \
      op start interval="0" timeout="90s" \
      op stop interval="0" timeout="100s"
    group gr_base controld lvmlockd LVM
    clone cl_base gr_base \
      meta interleave="true"
    commit
EOF.base
