RHEL6.5 kernel2.6.32-431.el6.x86_64 上記サーバにてネットワークのBONDING設定を行おうと思っております。 現象としましてはサーバに物理NICが2口あり(eth0,eth1)、2口を同じ馬鹿ハブに刺し、同じハブにぶら下げた適当なターゲットにping通信を行ったところ ・両方刺している時→通信OK ・eth0のみ刺さっている時→通信OK ・eth1のみ刺さっている時→通信NG という現象がでました。なぜ本現象が発生するのかお分かりになる方いらっしゃいますでしょうか？ 監視状態を見る感じですと問題なく動いてるようにも見えるのですが・・・馬鹿ハブだと動かないものなのでしょうか？ ↓下記設定ファイル↓ * /etc/modprobe.d/bond0.conf alias bond0 bondig * /etc/sysconfig/network-scripts/ifcfg-bond0 DEVICE=bond0 IPADDR=任意 NETMASK=任意 GATEWAY=任意 ONBOOT=yes BOOTPROTO=none BONDING_OPTS="mode=1 primary=eth0 miimon=100 updelay=500" DNS1=任意 DNS2=任意 * /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 MASTER=bond0 SLAVE=yes BOOTPROTO=none TYPE=Ethernet ONBOOT=yes * /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 MASTER=bond0 SLAVE=yes BOOTPROTO=none TYPE=Ethernet ONBOOT=yes ・動作確認 * cat /proc/net/bonding/bond0 ・NIC両方にさした場合→通信OK Ethernet Channel Bonding Driver: v3.6.0 (September 26, 2009) Bonding Mode: fault-tolerance (active-backup) Primary Slave: eth0 (primary_reselect always) Currently Active Slave: eth0 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 500 Down Delay (ms): 0 Slave Interface: eth0 MII Status: up Speed: 100 Mbps Duplex: full Link Failure Count: 2 Permanent HW addr: 74:d4:35:48:b5:e8 Slave queue ID: 0 Slave Interface: eth1 MII Status: up Speed: 100 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 74:d4:35:48:b5:e9 Slave queue ID: 0 ・eth0を抜きeth1を刺した状態→通信NG Ethernet Channel Bonding Driver: v3.6.0 (September 26, 2009) Bonding Mode: fault-tolerance (active-backup) Primary Slave: eth0 (primary_reselect always) Currently Active Slave: eth1 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 500 Down Delay (ms): 0 Slave Interface: eth0 MII Status: down Speed: Unknown Duplex: Unknown Link Failure Count: 2 Permanent HW addr: 74:d4:35:48:b5:e8 Slave queue ID: 0 Slave Interface: eth1 MII Status: up Speed: 100 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 74:d4:35:48:b5:e9 Slave queue ID: 0 ・eth0を刺しeth1を抜いた状態→通信OK Ethernet Channel Bonding Driver: v3.6.0 (September 26, 2009) Bonding Mode: fault-tolerance (active-backup) Primary Slave: eth0 (primary_reselect always) Currently Active Slave: eth0 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 500 Down Delay (ms): 0 Slave Interface: eth0 MII Status: up Speed: 100 Mbps Duplex: full Link Failure Count: 2 Permanent HW addr: 74:d4:35:48:b5:e8 Slave queue ID: 0 Slave Interface: eth1 MII Status: down Speed: Unknown Duplex: Unknown Link Failure Count: 2 Permanent HW addr: 74:d4:35:48:b5:e9 Slave queue ID: 0
