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

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 <a moz-do-not-send="true"

Hi Eneko<br>
<br>
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.<br>

Neither am I ;-) <br>

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.<br>
<br>
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.<br>
<br>
Cheers!<br>
