I am resending it and crossing my fingers that it is actually readable this time. --- Hello, I am trying to get LVS to load balance two web servers. Which seems like it should be easy to do. Especially since I have it successfully LVS working to load balance other services (mysql cluster, dns and smtp) on the same load balancers but I cannot get LVS to load balance http requests. I believe my issue is the same thing this poster mentions in the following message: http://archive.linuxvirtualserver.org/html/lvs-users/2006-07/msg00132.html "As a result, ldirectord was trying to add the rule again (-a) instead of editing it (-a), which causes an error and the weight does not change. Horms can explain more." When I start heartbeat I see the following in the /var/log/messages: Feb 7 10:19:28 loadb1 ldirectord[1392]: Resetting soft failure count: 192.168.100.31:8002 (tcp:192.168.100.16:80)Feb 7 10:19:28 loadb1 ldirectord[1392]: system(/sbin/ipvsadm -a -t 192.168.100.16:80 -r 192.168.100.31:8002 -g -w 1) failed: Therefore, my servers never get a weight of one: TCP 192.168.100.16:www rr -> 192.168.100.32:www Route 0 0 0 -> 192.168.100.31:www Route 0 0 0 If I take the same command from the log output and change it to edit (-e) rather than add (-a) my server gets a weight of one and works splendidly: /sbin/ipvsadm -e -t 192.168.100.16:80 -r 192.168.100.31:8002 -g -w 1 If someone can steer me in the right direction I would appreciate it, I have read the LVS documentation, many howto's and done a lot of googling on the topic to no avail. A bit about my configuration: Both load balancers are Ubuntu 9.10. I am using packages from my distribution which report the following versions: heartbeat: 2.99.2+sles11r9-5ubuntu1lidrectord: 2.99.2+sles11r95ubuntu1ipvsadm: 1:1.24-2.1 I do notice that ipvsadm seems very old, which makes me wonder if these packages are not well maintained on debian/ubuntu. ipvsadm -v shows: ipvsadm v1.24 2005/12/10 (compiled with popt and IPVS v1.2.0) A sample from my ldirectord.conf: virtual=192.168.100.16:80 real=192.168.100.31:8002 gate real=192.168.100.3 2:8002 gate service=http scheduler=rr protocol=tcp checktype=negotiate #checkport= 8002 request="ldirector.html" receive="." I have tried different check type's (off/on/connect/ping) to no avail. I always get the same error in my log. If there is any more information I can provide, please let me know and thanks in advance.
