Oh. That's simple: http://lartc.org/howto/lartc.loadshare.html # tc qdisc add dev eth1 root teql0 # tc qdisc add dev eth2 root teql0 # ip link set dev teql0 up Don't forget the 'ip link set up' command! This needs to be done on both hosts. The device teql0 is basically a roundrobbin distributor over eth1 and eth2, for sending packets. No data ever comes in over an teql device, that just appears on the 'raw' eth1 and eth2. But now we just have devices, we also need proper routing. One way to do this is to assign a /31 network to both links, and a /31 to the teql0 device as well: On router A: # ip addr add dev eth1 10.0.0.0/31 # ip addr add dev eth2 10.0.0.2/31 # ip addr add dev teql0 10.0.0.4/31 On router B: # ip addr add dev eth1 10.0.0.1/31 # ip addr add dev eth2 10.0.0.3/31 # ip addr add dev teql0 10.0.0.5/31 On 7/4/07, Alessandro Ferrari <alexferro at tiscali.it> wrote: > > How do you think to make NIC bonding? > > Alessandro > > ----- Original Message ----- > *From:* CA Lists <lists at creativeanvil.com> > *To:* drbd-user at lists.linbit.com > *Sent:* Tuesday, July 03, 2007 8:08 PM > *Subject:* [DRBD-user] GigE vs Bonded NICs > > I have 2 storage servers that use DRBD to sync the disks, with an > additional 2 servers that connect via iSCSI and mount an OCFS2 partition. > All 4 servers have dual gigabit network cards.
