During failover, you will lose sessions from the node that has gone away. New connections will be sent to the remaining real server(s).
I asked the same thing 3 months ago ;) http://lists.graemef.net/pipermail/lvs-users/2010-September/023555.html Happy new year to you too.

Subject: Re: [lvs-users] ldirectord and tomcat cluster Hi Darren, again ;-) what you do is .... check the source IP and route it always to the same tomcat node? It this is true - what's about fail-over? This does not work then. In my scenario the webapps store lots of information in memory and share it between each nodes. So I am freed during a breakdown. Isn't it better this way? Whishing you a happy new Year!

I don't do session replication with Tomcat, I found it not to work very well. Instead I just set anything you need sessions on to be source hash scheduler.

Subject: [lvs-users] ldirectord and tomcat cluster Hello list, I hope you can help all users who share this same problem: I use a 2 cluster node running on each tomat with session replication because I need load balancing (ldirector/ipvs) and on each node the same session information. I configured tomcat like described here: http://tomcat.apache.org/tomcat-6.0-doc/cluster-howto.html It seems to work well if I do not use ldirectord for balancing. (actually it checks port 80 [apache] ) virtual=10.10.11.139:80 checktype=negotiate fallback=127.0.0.1:80 protocol=tcp real=10.10.11.137:80 gate real=10.10.11.138:80 gate receive="Still alive" request="/test.html" scheduler=wlc service=http But if I activate ldirectord for port 8080 (tomcat) then I get in my web applications lots of "page can not be displayed" messages. Can anybody explain me why this happens or show how to configure it correctly? Thank you.
