first thanks for your time.

I'm having a problem with ldirectord that I can not solve, I comment my situation:

I have two nodes with pace maker and corosync and configure somes resources:

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:
