hi, did you make "ip_forward" active on lvs ? lvs must be default gw for
RSs. And, did you check RSs connection on LVS, because on lvs, RSs can not
seen.
root@m1045 ha]# ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 11.1.40.50:23 wlc
my lvs configuration is below (LVS/NAT)
Main Network 10.0.0.0/24
Main Router 10.0.0.254
LVS eth0 -> 10.0.0.100
eth0:0 -> 10.0.0.200 (Virtual IP for Virtual Service)
eth1 -> 172.16.1.1/24 (the gateway for RS1-RS6)
RS1 eth0 -> 172.16.1.101
RS2 eth0 -> 172.16.1.102
RS3 eth0 -> 172.16.1.103
RS4 eth0 -> 172.16.1.104
RS5 eth0 -> 172.16.1.105
RS6 eth0 -> 172.16.1.106

Hi Mehmet CELIK,
Thanks for your reply.
I have changed my piranha configuration as per your instruction. Still
it is not working. Configuration is follows.
LVS eth0 -> 10.1.40.45
eth0:0 -> 10.1.40.50
LVS eth1 -> 11.1.40.45
eth1:0 -> 11.1.40.50
RS eth0 -> 10.1.40.34
My lvs.cf is as follows:
serial_no = 12
primary = 11.1.40.45
service = lvs
network = nat
nat_router = 10.1.40.50 eth0:0
nat_nmask = 255.255.255.0
debug_level = NONE
virtual Telnet {
active = 1
address = 11.1.40.50 eth1:0
vip_nmask = 255.255.255.0
port = 23
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 m1034 {
address = 10.1.40.34
active = 1
weight = 100
}
}
After this I am starting pulse service in my LVS.
Following output I am getting inmy LVS on passing ipvsadm -L -n comman.
[root@m1045 ha]# ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 11.1.40.50:23 wlc
[root@m1045 ha]#
Note: Here there is no route for forward path to Real server. I am
guesing piranha is not updating it.
Log from CONTROL/MONITORING Tab of Piranha:
What should I do after this?
Thanks,
Santosh

hi, firstly, the piranha is not supporting lvs/dr or lvs/tun right now.
may
in future..
the following paragraph is from
http://www.redhat.com/support/resources/howto/piranha/
"Currently, the LVS cluster supports one routing method,
Network Address Translation (NAT). (In the future, tunneling
and direct routing will be added.)"
secondly, your configuration is wrong.
LVS eth0 -> 10.1.40.45
eth0:0 -> 10.1.40.40
LVS eth1 -> 11.1.40.45
eth1:0 -> 11.1.40.40
RS eth0 -> 10.1.40.34
you should write "10.1.40.40 and eth0:0" to "NAT Router IP and Device"
on
piranha. is not eth1:1. the default gw should be set "10.1.40.40" for
RS.
Then, "Virtual Service" IP should be set "11.1.40.40 and eth1:0".
REQUEST = client -> (11.1.40.40) ipvs forward on lvs (10.1.40.40)
->
(10.1.40.34) RS
RESPOND = client <- (11.1.40.40) NAT on lvs-gateway (10.1.40.40)
<-
(10.1.40.34) RS
if you change configuration, you must restart pulse service.
have a nice day.
