Quiesce server
When the Quiesce server radio button is selected, anytime a new real server node comes
online, the least-connections table is reset to zero so the active LVS router routes requests
as if all the real servers were freshly added to the cluster. This option prevents the a new
server from becoming bogged down with a high number of connections upon entering the
cluster.

The LVS router can monitor the load on the various real servers by using either
rup

rup
from the drop-down menu, each real server must run the
rstatd
service. If you select
ruptime
, each real server must run the
rwhod
service.
