This is all new to me. Please bear with me. Sorry if I don't phrase my problem correctly. I'd like to set ip floating to use HAproxy and Keepalived.
I have the following ips:
LB1: 192.168.1.27 #first load balancer
LB2: 192.168.1.32 #second load balancer
www1: 192.168.1.28 #first web server
www2: 192.168.1.29 #second web server
floating ip: 192.168.1.200
When I turn off load balancer 1 (LB1), traffic is not getting redirected to floating ip. I don't know what to check so I can make this whole setup run successfully. I suspect that LB2 is the problem (apart from me:)) as the floating ip doesn't do its job when LB1 is down.
I also followed the checking process section on the link below '8. Verify proper failover' but to no avail: How to create Floating IP and use it to configure HAProxy. Individually, the 5 ips work fine only when HAproxy is on. That's all I can say.
Could you please help me? Thanks.

On LB1 and LB2, in Keepalived:
nano /etc/sysctl.conf
added net.ipv4.ip_nonlocal_bind=1
sysctl -p
on lb1:
sudo service keepalived alived stop
then checked if lb2 is working. It is!!! But when Haproxy on LB1 is down, traffic still doesn't get redirected to LB2.
