I'm running Corosync + Pacemaker on Ubuntu 14.4. I set up two nodes with two VIPs, and when I bring pacemaker down in one node, the VIPs do go to the other, but no traffic actually goes through the system until I manually run ifdown eth1 and ifup eth1 (the VIPs are on eth1) on that node. This is true for both nodes.

I can see that the VIPs did get transferred ok using ifconfig. But running bmon I see that no traffic goes through until I run ifdown / ifup.

crm configure show:

node $id="6" node1
node $id="3" node2
primitive VIP_3 ocf:heartbeat:IPaddr2 \
    params ip="10.0.1.112" nic="eth1" iflabel="3" \
    op monitor interval="10s" on-fail="restart" \
    op start interval="0" timeout="1min" \
    op stop interval="0" timeout="30s"

/etc/network/interfaces:

iface eth0 inet static
    address 10.0.0.192
    netmask 255.255.255.0
    gateway 10.0.0.138

auto eth1

    post-up ip route add 10.0.1.0/24 dev eth1 table 11
    post-up ip rule add from 10.0.1.0/24 table 11
    post-up ip rule add to 10.0.1.0/24 table 11
    pre-down ip rule delete table 11
    pre-down ip rule delete table 11
    pre-down ip route flush table 11

Any ideas of what I'm doing wrong? I would expect that after Pacemaker starts up the IP addresses, traffic will start flowing through them without need for running ifdown eth1 and ifup eth1.

Thanks!
