reweighting a server

[Brian Edmonds <bedmonds@xxxxxxxxxxx>]

Is there a single operation way to reweight a server?  I'd like to
rebuild the web software on one of my real servers without affecting any
users, so I figure reweighting its lvs rule to zero and waiting for the
active connections to go to zero before making any changes is the way to
go.  I don't see any ipvsadm options for changing a weight.  Will
deleting the rule and re-adding an identical one with weight zero effect
active connections?
