voici mon script de gestion du bonding. Je précise que mon Dom0 possede 2 interfaces réseau : - un bonding - une eth qui sert de heartbeat Je cré donc 2 bridge : - brnet : pour le réseau local - brcluster : pour le réseau heartbeat Il est ensuite important de paramétrer ses DomU avec brnet et brcluster. par ex : vif = [ 'mac=00:16:3E:20:C8:20 , bridge=brnet' , 'mac=00:16:3E:20:C8:22 , bridge=brcluster' ] ----------- début du script bond-network-bridge -------------------- #!/bin/sh # Usage: transfer_addrs src dst # Copy all IP addresses (including aliases) from device $src to device $dst. transfer_addrs () { local src=""> local dst=$2 # Don't bother if $dst already has IP addresses. if ip addr show dev ${dst} | egrep -q '^ *inet ' ; then return fi # Address lines start with 'inet' and have the device in them. # Replace 'inet' with 'ip addr add' and change the device name $src # to 'dev $src'. ip addr show dev ${src} | egrep '^ *inet ' | sed -e " s/inet/ip addr add/ s@\([0-9]\+\.[0-9]\+\.[0-9]\+\.[0-9]\+/[0-9]\+\)@\1@ s/${src}/dev ${dst}/ " | sh -e # Remove automatic routes on destination device ip route list | sed -ne " /dev ${dst}\( \|$\)/ { s/^/ip route del / p }" | sh -e } # Usage: transfer_routes src dst # Get all IP routes to device $src, delete them, and # add the same routes to device $dst. # The original routes have to be deleted, otherwise adding them # for $dst fails (duplicate routes). transfer_routes () { local src=""> local dst=$2 # List all routes and grep the ones with $src in. # Stick 'ip route del' on the front to delete. # Change $src to $dst and use 'ip route add' to add. ip route list | sed -ne " /dev ${src}\( \|$\)/ { h s/^/ip route del / P g s/${src}/${dst}/ s/^/ip route add / P d }" | sh -e } # Usage: create_bridge bridge create_bridge () { local bridge=$1 # Don't create the bridge if it already exists. if ! brctl show | grep -q ${bridge} ; then brctl addbr ${bridge} brctl stp ${bridge} off brctl setfd ${bridge} 0 fi ip link set ${bridge} up } # Usage: add_to_bridge bridge dev add_to_bridge () { local bridge=$1 local dev=$2 # Don't add $dev to $bridge if it's already on a bridge. if ! brctl show | grep -q ${dev} ; then brctl addif ${bridge} ${dev} fi } # Usage: show_status dev bridge # Print ifconfig and routes. show_status () { local dev=$1 local bridge=$2 echo '============================================================' ip addr show ${dev} ip addr show ${bridge} echo ' ' brctl show ${bridge} echo ' ' ip route list echo ' ' route -n echo '============================================================' } op_start () { create_bridge brnet add_to_bridge brnet vif0.0 add_to_bridge2 brnet bond0 transfer_addrs bond0 brnet transfer_routes bond0 brnet create_bridge brcluster add_to_bridge brcluster vif1.0 add_to_bridge2 brcluster eth2 transfer_addrs eth2 brcluster transfer_routes eth2 brcluster } op_stop () { transfer_routes brnet bond0 ip link set brnet down brctl delbr brnet transfer_routes brcluster eth2 ip link set brcluster down brctl delbr brcluster } # adds $dev to $bridge but waits for $dev to be in running state first add_to_bridge2() { local bridge=$1 local dev=$2 local maxtries=10 echo -n "Waiting for ${dev} to negotiate link." for i in `seq ${maxtries}` ; do if ifconfig ${dev} | grep -q RUNNING ; then break else echo -n '.' sleep 1 fi done if [ ${i} -eq ${maxtries} ] ; then echo '(link isnt in running state)' ; fi add_to_bridge ${bridge} ${dev} } case "${1}" in start) op_start ;; stop) op_stop ;; status) show_status ${netdev} ${bridge} ;; *) echo "Unknown command: ${1}" >&2 echo 'Valid commands are: start, stop, status' >&2 exit 1 esac ----------- fin du script bond-network-bridge -------------------- J'espere que cela vous aidera.
