Keepalived and 2 director servers that are realservers as well

[Jimmy Hedman <jimmy.hedman@xxxxxxxxxxxx>]

Hi,
I'm trying to set up a cluster with 2 directors that also are part of
the real server cluster and I use keepalived to handle the failover, but
keepalived keeps setting up the ipvs "routes" on the backup machine
which makes the traffic "loop". The load-balancing works when im not
running keepalived on the backup or on the master, but then i don't have
the failover...

Im running red hat 8.0 with the hidden patch applied, ipvs 1.0.4,
keepalived 1.0.0 as rpm from keepalived.org.


This is my configs:

master:
global_defs {
    lvs_id lvs_test
}
vrrp_instance VI_1 {
    interface eth0
    state MASTER
    lvs_sync_daemon_interface eth0
    virtual_router_id 51
    priority 150
    advert_int 1
    virtual_ipaddress {
        192.168.2.221
    }
    debug
    preempt
}

virtual_server 192.168.2.221 80 {
    delay_loop 20
    lb_algo wlc
    lb_kind DR
    ha_suspend
    protocol TCP

    real_server 192.168.2.220 80 {
        weight 40
        TCP_CHECK {
            connect_timeout 3
        }
    }
    real_server 192.168.2.194 80 {
        weight 20
        TCP_CHECK {
            connect_timeout 3
        }
    }
}

backup:


global_defs {
    lvs_id lvs_test2
}
vrrp_instance VI_1 {
    interface eth0
    state BACKUP
    lvs_sync_daemon_interface eth0
    virtual_router_id 51
    priority 100
    advert_int 1
    virtual_ipaddress {
        192.168.2.221
    }
    debug
    preempt
}

virtual_server 192.168.2.221 80 {
    delay_loop 20
    lb_algo wlc
    lb_kind DR
    ha_suspend
    protocol TCP

    real_server 192.168.2.220 80 {
        weight 40
        TCP_CHECK {
            connect_timeout 3
        }
    }
    real_server 192.168.2.194 80 {
        weight 20
        TCP_CHECK {
            connect_timeout 3
        }
    }
}




Many thanks in advance,
Jimmy Hedman
