Hi,
I'm running into a problem with ifup-ib on RH 5.3. I've setup a bonded
interfaces over 2 ports of a HCA as follows
# cat ifcfg-bond0
DEVICE=bond0
USERCTL=no
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.168.33.219
NETMASK=255.255.254.0
NETWORK=192.168.32.0
BROADCAST=192.168.33.255
BONDING_OPTS="mode=active-backup miimon=100 downdelay=5000 updelay=5000"
IPV6INIT=no
MTU=65520
# cat ifcfg-ib1
DEVICE=ib1
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none
HOTPLUG=no
CONNECTED_MODE=yes
MTU=65520
# cat ifcfg-ib0
DEVICE=ib0
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none
HOTPLUG=no
CONNECTED_MODE=yes
MTU=65520
When the network service comes up, it executes ifup-ib to bring up ib0 &
ib1. However, this script has the following which causes it to exit
before it configures these interfaces to run in connected mode.
69 # slave device?
70 if [ "${SLAVE}" = yes -a "${ISALIAS}" = no -a "${MASTER}" != ""
]; then
71 /sbin/ip link set dev ${DEVICE} down
72 echo "+${DEVICE}" > /sys/class/net/${MASTER}/bonding/slaves
2>/dev/n ull
73
74 if [ -n "$ETHTOOL_OPTS" ] ; then
75 /sbin/ethtool -s ${REALDEVICE} $ETHTOOL_OPTS
76 fi
77
78 exit 0
79 fi
...
120 # We have to set connected mode before we set the MTU since
connected mo de
121 # changes our maximum allowed MTU
122 if [ "${CONNECTED_MODE}" = yes -a -e
/sys/class/net/${DEVICE}/mode ]; th en
123 echo connected > /sys/class/net/${DEVICE}/mode
124 fi
125
126 if [ -n "${MTU}" ]; then
127 ip link set dev ${DEVICE} mtu ${MTU}
128 fi
Is this a bug or is there a different way to bond together 2 connected
mode interfaces?
# rpm -qf /etc/sysconfig/network-scripts/ifup-ib
