I know this is what you want, but one of the reasons you
use an LVS is so that you can bring down realservers
for planned maintenance and bring them up again without
interruption of service to clients. This way a client will
never be presented with a maint page.
So you'd remove realserver_1 with ipvsadm, wait for
connections to drop, upgrade, check out from a local
(non lvs) client that it looks OK, put realserver_1
back into the LVS and at the same time remove realserver_2..n.
etc.
Why don't you want to do this?
