Bonded interfaces on linux are active-backup, so you have a 1Gb

I don't think this is the case. You can configure many modes on
bonded interfaces; only a few of them are active-backup. For details,
see https://www.kernel.org/doc/Documentation/networking/bonding.txt
Hi Eneko
I spoke based on my experience, and I'm not a network expert, so if
I'm wrong, please excuse me (and enlight me! :)). What I meant is I
know there are several modes, but none of them can "sum" both network
interfaces bandwith (i.e.: 1Gb eth + 1Gb eth becoming a virtual 2Gb
interface). I think the mode would be balance-rr but that mode come
with many troubles.
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.
Cheers!
Eneko
