lvs & keepalived with misc_check problem

[Bjoern <lists-lvs-users@xxxxxxxxxxxxxxxxx>]

Hello,

i try to use keepalived with MISC_CHECK and misc_dynamic for
dynamically setting the weight of real servers. The keepalived is
starting the check-script correctly and detects that it has to
change the weight:

Dec 21 11:59:08 loadbalancer Keepalived_healthcheckers: Changing weight from 
78 to 18 for active service [192.168.10.1:80] of VS [192.168.4.12:80]

But the keepalived is not able to change the weight, the log says:

Dec 21 11:59:08 loadbalancer Keepalived_healthcheckers: IPVS: No such 
destination


I configured the virtual server like this:

virtual_server 192.168.4.12 80 {
        protocol TCP
        lb_kind DR
        lb_algo wrr
        delay_loop 10
        real_server 192.168.10.1 80 {
                weight 1
                MISC_CHECK {
                        misc_path "/root/weight.sh 1"
                        misc_timeout 10
                        misc_dynamic
                }
        }
        real_server 192.168.10.2 80 {
                weight 1
                MISC_CHECK {
                        misc_path "/root/weight.sh 2"
                        misc_timeout 10
                        misc_dynamic
                }
        }
}


I hope somebody knows this problem and could give me some hint.


Best regards,
