[PVE-User] 3 proxmox 2.1 servers, 2 switches, HA

[Patrice Levesque]

Hi,

just started using Proxmox and I'm impressed.  There's a network setup
though I'm not sure how to do.

But let me first show you my fine ASCII artistic talents.

I want to use link aggregation (switches are Cisco 2960G if you need to
know), so no problem, I can bind two interfaces together via bonding
rules in /etc/network/interfaces and 802.3ad mode.

Now I'd like the Switch 2 to become a fail-over (the switches are *not*
stacked), and hence I'd like to use only one switch at a time.  My first
idea was to meta-bond the two bonding interfaces in active-backup mode,
but layering the bonding driver appears to be a bad idea according to
what I read here :
http://sourceforge.net/projects/bonding/forums/forum/77912/topic/2593462?message=5691669

The above link refers to bonding option ad_select={1,2} (I guess), but
I'm quite unsure if it'll fulfill my need and if so, how to put all of
this together in /etc/network/interfaces.

Has anybody done a similar setup / has experience with multiple switches
to share?


Thanks,
