What I would love to see with LVS is the VSR approach and
a proper and working imlementation of VRRP or CARP.
Before CARP existed I had hoped to use Alexandre's
keepalived as a VRRPd to control failover on a pair of
routers running services that I wanted to failover with the
routers, eg dhcpd, squid, firewall, but keepalived was too
tied to LVS to do it easily.
I knew I could do it with Horms' code. I just wanted to try
it with VRRPd. I never revisited the issue when CARP came
along. Maybe it can do what I want.
If someone does something with VRRRP/CARP and LVS it would
be nice if the VRRP wasn't directly tied to LVS, ie the
VRRRP could be used for other failovers as well.
I've just recently set up a 2208 switch using one VSRs and
2 VIRs, doing failover when either the link or the DGW is
not reachable anymore. The sexy thing about this setup is
that you don't need to fiddle around with arp problems and
you don't need to have NAT, so balancing schedulers can
get meaningful L7 information.
how do they detect media/gw failure?
