[linux-lvm] piranha on Fedora core 6, piranha-gui fails, pulse running_real servers not switching



Hi ,
I am configuring lvs nat router with piranha-0.7.12-1 on Fedora Core 6 machines
When i turn off service of one of my real service it is not switching
to second real server. I can access and see logs of connection in
ipvsadm -L.
I edited sample.cf file and copied as lvs.cf. as my piranha-gui is not
running due to some missing appache modules.

What am i missing here? Is it necessary to use piranha-gui to
configure pulse? I am using Fedora core 6.
When I switch off one of my real server it is not switching to real
server2. My logs showing errors in nanny for reading load. Do i need
to make some changes on my real servers?

Thanks and regards
