[Linux-HA] my installation of ClusterIP

[Ilo Lorusso]

Hi ,


ive been following the http://www.linux-ha.org/ClusterIP

and want to install a two node cluster as shown in the guide ..

ive manged to get it up and going but have a few kinks to iron out..

I ip alias both servers as directed and add the following command in on both
servers ,

iptables -I INPUT -d 172.20.128.112  -i eth0 -p icmp -j CLUSTERIP \
  --new --clustermac 01:02:03:04:05:06 --total-nodes 2 \
  --local-node 1 --hashmode sourceip

start heartbeat configured as closey matched to the documentions..
I can ping my virtual and get a responce and see I
 I can see that I recieve responces from both servers so it looks like
active/active loadsharing is working..

now, if I pull a network cable out and put it back, I notice

that Heatbeat adds this iptables command to both servers

iptables -A INPUT -d 172.69.128.112 -i eth0 -j CLUSTERIP --new --hashmode
sourceip-sourceport --clustermac b1:07:84:ab:56:34 --total-nodes 2
--local-node 2 --hash-init 0

and randomly either one or both nodes crash with a kernel panics.. and
mentions ipt_CLUSTERIP
any answers around this? on why it kernel panics?
