[Pacemaker] CLUSTERIP/iptables interaction

Hi all

I am doing some tests with clusterip and pacemaker/heartbeat on Centos 
5.4, using the clusterlabs repo

My resource looks like:
primitive CLUSTERIP_21 ocf:heartbeat:IPaddr2 \
	op monitor interval="10" timeout="20" start-delay="0" \
	params ip="10.202.4.21" nic="eth0" cidr_netmask="24" 
clusterip_hash="sourceip-sourceport" \
	meta resource-stickiness="0"
clone clone_CLUSTERIP_21 CLUSTERIP_21 \
	meta clone-max="2" globally-unique="true" clone-node-max="2"


This start up fine, and adds an iptables rule correctly, however, if I 
restart the iptables service the clusterip rule gets removed.

I then get the below errors in my log file.  These continue without 
stopping.

It seems that the ipaddr2 script is not currently capable of recreating 
the iptables rule if it get inadvertently removed.

It this known behaviour?  If not, where does my error lie?

Regards

Chris
