The problem is in the ipvsadm only show a one real IP, when i configured two now, show the ldirector.cf:



root@ldap1:/home/mamartin# ipvsadm

        scheduler=wrr
        protocol=tcp
        checkport=389
     checktype=on


and in the logs I see nothing clear:

Same issue after upgrading i386 servers from 2.6.32 kernel and 1.25 ipvadm to 3.2.0 kernel and 1.26 ipvadm, while ipvsadm shows oly one /proc/net/ip_vs shows all real servers.

On a newly installed amd64 all is working fine.

To solve the issue i applied the patch posted here http://archive.linuxvirtualserver.org/html/lvs-users/2011-08/msg00033.html and discussed here https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=685495
