[OmniOS-discuss] Keepalived in an LX branded zone

[Serge Fonville]

Hi,

I am currently trying to setup keepalived in an LX branded zone.

Since I get a lot of errors that might be related to the fact it is an LX
branded zone, I was wondering if someone would be so kind to shed their
light on it.

Especially since I never setup keepalived before, I am unsure if these
errors are caused by the fact it is an LX branded zone, of just
misconfiguration of keepalived.

# Inside the zone
keepalived.conf

> global_defs {    router_id haproxy01
>     vrrp_version 3
> }
>
> vrrp_script check_haproxy {
>     script "/etc/keepalived/check_haproxy.sh"
>     interval 0.05
>     fall 2
>     rise 2
> }
>
> vrrp_instance haproxy_instance {
>     state MASTER
>     interface haproxy01vnic0
>     virtual_router_id 25
>     priority 150
>     advert_int 0.05
>     virtual_ipaddress {
>         192.168.1.25/2 label haproxy01vnic0:0
>     }
>     track_script {
>         check_haproxy
>     }
