I am trying to setup up a simple LVS cluster to test a configuration I plan
on implementing with a customer.
Any help would be GREATLY appreciated and will contribute to additional
sales of Redhat ES and Redhat Cluster Suit.
2 boxes in my lab two laptops intel boxes running Redhat Ent V3 with
Redhat Cluster Suite installed on both.

Virtual IP Address 192.168.1.111
Real Box 1 IP: 192.168.1.108 (also the LVS Director)
Real Box 2 IP: 192.168.1.109
Each real box is running HTTP with a slightly different page so I can tell
which is serving.
Problem: I have tried both NAT routing and Direct Routing and in all cases
the servers serve the pages normal (going to direct IP) but when I use the
VIP address the page is returned very slowly (up to a minute vs about a
second directly)
I have tried a number of configuration changes, here is my latest
incarnation:
serial_no = 79
primary = 192.168.1.108
service = lvs
backup_active = 1
backup = 192.168.1.109
heartbeat = 1
heartbeat_port = 539
keepalive = 6
deadtime = 18
network = direct
debug_level = NONE
virtual willwecm3 {
active = 1
address = 192.168.1.111 eth0:1
vip_nmask = 255.255.255.0
port = 80
send = "GET / HTTP/1.0\r\n\r\n"
expect = "HTTP"
use_regex = 0
load_monitor = none
scheduler = wlc
protocol = tcp
timeout = 6
reentry = 15
quiesce_server = 0
server willwecm1 {
address = 192.168.1.108
active = 1
weight = 1
}
server willwecm2 {
address = 192.168.1.109
active = 1
weight = 2
}
server willwecm1 {
address = 127.0.0.1
active = 1
weight = 1
}
}
