If you're not running a healthcheck framework over the top of LVS, you
won't detect the failure. LVS itself only does load balancing - not
system monitoring.

You may want to use keepalived, ldirectord or some other consolidated
application that can manage your system for you both in terms of LVS
setup and server/service monitoring.
