[lvs-users] heartbeat+ldirectord NAT gateway failover

[Sid Stuart]

Hi,

I am using heartbeat and ldirectord in a NAT configuration to support HTTP
services. The problem with this configuration is the real server needs to
route traffic back through the active LVS server. This means the router
address assigned to the real servers needs to failover between LVS nodes. Is
there a standard mechanism to do this? I have not found it in the
documentation or on this mailing list.

My first thought is to configure a dummy service in heartbeat that will
cause it to generate register the virtual IP. For instance, if I use
172.16.1.1 as the virtual gateway address, I could create an haresources
entry,

lb1 172.16.1.1 dummy

Where dummy is a script that takes stop and start arguments but doesn't
actually do anything.

Is there a better solution than this?
