[Linux-cluster] doubts in Piranha

[mehmet celik]

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.
