I'm not sure this would fix your problem but you should enable virtual IPs
on your nodes in the first place.. The following is to be done on both
nodes:

=================================================================
# vim /etc/sysctl.conf                /* Add the line below to enable a
shared / virtual IP */
net.ipv4.ip_nonlocal_bind=1

# sysctl -p                               /* to update the your system with
the new configuration */

# ping <the virtual IP>               /* this should give you a response */
=================================================================

I got this from:

I hope it helps
