Replacing ldirectord/heartbeat with LVS/piranha/pulse

[Sean Drill]

Hi there

I have been having some issues implementing a new load balancing system,
and was hoping someone could over some advice.

Our current configuration is configured using ldirectord. The active
node hosts all the virtual servers. Each virtual server will have an
active real server, and a backup real server. All the traffic will be
directed to the active real server, unless that server becomes
unreachable, at which point all traffic will be directed to the backup
server. In other words, a traditional real/fallback system.

I am however only able to get piranha/lvs to do load sharing. In this
case as long as both servers are set to UP, then traffic will be
balanced between all servers (determined by load balancing scheme and
weighting.) What I am attempting to do is create a virtual server in
LVS, which has two active REAL servers, however direct traffic only to
one of them, unless otherwise directed or if the active member fail,
then direct traffic to the backup. I am basically trying to replicate
the ldirectord/heartbeat system with piranha/lvs/pulse.

Any directions which can be offered would be great appreciated.

Regards,
Sean
