[DRBD-user] Directly connected GigE ports bonded together no switch

Sorry if this is covered elsewhere.
I know the Linux Bonding FAQ is supposed to talk about this, but I
didn't see anything specific in it on what parameters to use.
Basically, I want to bond two GigE ports between two servers which are
connected with straight cables with no switch and use them for DRBD.
I tried the various bonding modes with "miimon=100", but none of them
worked. Say the eth1 ports on both servers were cabled together, and the
same for eth5. Then, I could create the bond with eth1 and eth5.
However, if I downed one of the ports on one server, say eth1, it would
failover on that server to eth5, but the other server would not failover
Eventually, I decided to use "arp_interval=100" and "arp_ip_target=<ip
of other bonded pair>" instead of "miimon=100". This seems to work as
I expected, with the bond properly failing over.
Is this the right way to do this kind of bonding?
Also, right now I'm using "mode=active-backup". Would one of the other
modes allow higher throughput and still allow automatic failover and
transparency to DRBD?
