Re: Keepalived track_script and failover

Ok so then my configs would look like this, right?

Host1:

global_defs {
    notification_email {
        <removed>
    }
    notification_email_from <removed>
    smtp_server <removed>
    smtp_connect_timeout 30
}

vrrp_script chk_haproxy {
    script "killall -0 haproxy"
    interval 1
    weight -51
}

vrrp_instance VI_1 {
    interface eth0
    state BACKUP
    virtual_router_id 51
    priority 52
    nopreempt

    smtp_alert

    authentication {
       auth_type PASS
       auth_pass 1234qwer
    }

    virtual_ipaddress {
        192.168.12.5
        192.168.12.10
    }

    track_script {
       chk_haproxy
    }
}

Host2:

global_defs {
    notification_email {
        <removed>
    }
    notification_email_from <removed>
    smtp_server <removed>
    smtp_connect_timeout 30
}

vrrp_script chk_haproxy {
    script "killall -0 haproxy"
    interval 1
    weight -51
}

vrrp_instance VI_1 {
    interface eth0
    state BACKUP
    virtual_router_id 51
    priority 51
    nopreempt

    smtp_alert

    authentication {
       auth_type PASS
       auth_pass 1234qwer
    }

    virtual_ipaddress {
        192.168.12.5
        192.168.12.10
    }

    track_script {
       chk_haproxy
    }
}

Add 2 to each of your priorities so they don't go into negative numbers on the secondary on a failure, and make the weight a -51 that will cause an offset of 50. In vrrp a differential of 50 supersedes a nopreempt

I made the requested changes and it works now. Fantastic. Thank you everyone!
Now, if I want to add nopreempt to prevent fail backs can I do that safely by just adding that keyword to each config file and setting a weight of -50 to the chk_haproxy script?
