Hello,
Already saw some similar problems on the list and elsewhere in the net.
But there was never a real solution for my problem. Don't think i'm the
only one who has/had this problem.
I have two server (CentOS 5). Both running heartbeat and ldirectord. On
the same servers there are a SMTP servers running which should be load
balanced by ldirector.
Over all it works very fine. But after restarting the real server
heartbeat sets my lo:0 interface down which is needed to allow
connections to the real server. (lo:0 is configured with the VIP of the
cluster). If i set the interface back up manually again everything works
fine.
Here are my configurations:

One idea i had was to define a resource for the lo:0 interface which is
running on all servers where the resource of the VIP is not running. But
don't know how to do that. An that may is not the clean way.
So hopefully there is somewhere outside which can help me.
Thank you very much
