Neither am I ;-)
Usually you need more than one network connection to use different
bonded slaves bandwidth. If you just use one connection (i.e. a scp)
then you will only get 1Gbit max. but if you have multiple concurrent
network connections then you can use all 2 Gbit, using LACP for example.
In a Proxmox-DRBD setup, each VM using drbd devices will open
independent connections so you should be able to use near all the
available bandwidth in a bonded interface.
