From c771f395699e10a534c05bdb790843d74c4898c9 Mon Sep 17 00:00:00 2001 From: Alex Harpin Date: Tue, 6 May 2014 23:41:17 +0100 Subject: [PATCH] bonding: use hwaddr of the slave rather than the master When a bonded interface is brought up, any slaves included in the bond have their hardware address set to that of the bond master. Although this allows an interface to be brought up on start up, when the configuration file is imported into the booted system it prevents the bonded interface being successfully restarted. The fix involves obtaining the hardware address of the slaves before they are added to the bond and then using this value in the configuration file. --- modules.d/40network/ifup.sh | 1 + modules.d/45ifcfg/write-ifcfg.sh | 6 +++++- 2 files changed, 6 insertions(+), 1 deletion(-) diff --git a/modules.d/40network/ifup.sh b/modules.d/40network/ifup.sh index ede018832f..fd84e4cd0f 100755 --- a/modules.d/40network/ifup.sh +++ b/modules.d/40network/ifup.sh @@ -188,6 +188,7 @@ if [ -e /tmp/bond.${netif}.info ]; then for slave in $bondslaves ; do ip link set $slave down + cat /sys/class/net/$slave/address > /tmp/net.${netif}.${slave}.hwaddr echo "+$slave" > /sys/class/net/$bondname/bonding/slaves linkup $slave done diff --git a/modules.d/45ifcfg/write-ifcfg.sh b/modules.d/45ifcfg/write-ifcfg.sh index 7f997a2afd..fb388bcb8e 100755 --- a/modules.d/45ifcfg/write-ifcfg.sh +++ b/modules.d/45ifcfg/write-ifcfg.sh @@ -206,7 +206,11 @@ for netup in /tmp/net.*.did-setup ; do echo "TYPE=Ethernet" echo "ONBOOT=yes" echo "NETBOOT=yes" - echo "HWADDR=\"$(cat /sys/class/net/$slave/address)\"" + if [ -e /tmp/net.${netif}.${slave}.hwaddr ]; then + echo "HWADDR=\"$(cat /tmp/net.${netif}.${slave}.hwaddr)\"" + else + echo "HWADDR=\"$(cat /sys/class/net/$slave/address)\"" + fi echo "SLAVE=yes" echo "MASTER=\"$netif\"" echo "NAME=\"$slave\"" -- 1.9.3
