[Linux-cluster] doubts in Piranha

Wed Jul 11 13:39:00 UTC 2007

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.

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

ipvsadm -L -n

TCP 10.0.0.201:80  rr
  -> 172.16.1.101:80    Masq  1   0   X
  -> 172.16.1.102:80    Masq  1   0   X
  -> 172.16.1.103:80    Masq  1   0   X
  -> 172.16.1.104:80    Masq  1   0   X
  -> 172.16.1.105:80    Masq  1   0   X
  -> 172.16.1.106:80    Masq  1   0   X

have a nice day..
