before making your first connection, make sure the supported protocols
overlap. Consider `head -n1 /proc/drbd`:
version: 18.104.22.168 (api:88/proto:86-94)
Load the new DRBD module on one of your nodes and compare the "proto"
entry to your old one. If there's an overlap, I think it will be safe to
bring your devices up.
