[Keepalived-devel] Weight is not used on wlc ?

[Christian J. <chr...@st...>]

Hallo,

I have been using keepalived now for about 6 months and I must say I am
Impessed how good it works, thanks a lot Alexandre :)

Now I have a small Problem. I have 2 Real Servers which do the same task,
but only one is supposed to do the work, then other is a Standby failover
Server.

I thought it should work like this, but it dosen't :

virtual_server 10.0.0.238 3699 {
    delay_loop 120
    lb_algo wlc
    lb_kind NAT
    persistence_timeout 50
    nat_mask 255.255.255.0
    protocol TCP

    real_server 10.0.3.17 3699 {
        weight 1000
        TCP_CHECK {
                connect_timeout 3
        connect_port 3699
        }
    }

    real_server 10.0.3.18 3699 {
        weight 1
        TCP_CHECK {
                connect_timeout 3
        connect_port 3699
        }
    }

}

Example Outputs of ipvsadm :

TCP  10.0.0.238:3699 wlc persistent 50
  -> 10.0.3.18:3699            Masq    1      0          2
  -> 10.0.3.17:3699            Masq    1000   0          0

TCP  10.0.0.238:3699 wlc persistent 50
  -> 10.0.3.18:3699            Masq    1      0          3
  -> 10.0.3.17:3699            Masq    1000   0          3

TCP  10.0.0.238:3699 wlc persistent 50
  -> 10.0.3.18:3699            Masq    1      0          2
  -> 10.0.3.17:3699            Masq    1000   0          4

It still uses the Server with weight 1 very offen - something like every
second or third time.
Previous I used rr an weight 100 with both servers. Could that be the
problem ? Is that "saved" somewhere ?

Any hint ?

System :
RedHat 7.2
Kernel 2.4.20-18.7.hidd.ipvs109.cipe154
