Hello Darren,
Please check your Figure against the LVS-DR standart .
i.e http://www.austintek.com/LVS/LVS-HOWTO/HOWTO/LVS-HOWTO.LVS-DR.html
Please note that the LVS-DR Common setup are 2 ( or more ) real servers and 2
directors .
Please note its Common that the real servers are seperat nodes
Please note that Corosync & pachemaker needs to be have an Group for the VIP +
ldirectord , otherwise that not work out.
Corosync setup Virtual IP, Colocation of IP - sample ( see i.e
http://clusterlabs.org/wiki/Using_ldirectord )
crm configure primitive WEBIP ocf:heartbeat:IPaddr2 op monitor interval="60"
timeout="20" params ip="192.168.43.14" nic="eth0:1" cidr_netmask="32" \
lvs_support="true" is-managed="true" multiple-active="stop_start"
target-role="Started"
crm configure primitive LVS ocf:heartbeat:ldirectord params
configfile="/etc/ha.d/ldirectord.cf" op monitor interval="60" timeout="120"
op start timeout="120" op stop timeout="120"
crm configure colocation LVS_Colo inf: LVS WEBIP:Master
crm configure order LVS_after_WEBIP inf: WEBIP:promote LVS:start
crm configure group LVSGROUP MAILIP SQLIP WEBIP LDAPIP LVS

>
> Hi all,
>
> I have a 2 node Pacemaker cluster using ldirector to control my IPVS rules.
>
> I'm setting it up in the same way I've done for years, put the VIP on
> loopback as /32, and also as an extra IP on eth0 as /24.
>
> The cluster will add the VIP to eth0 as 192.168.1.10/24 on one of the
> nodes, and the same VIP will be on lo as 192.168.1.10/32 on both nodes.
>
> If I try to access 192.168.1.10 on the node with the VIP active on eth0 and
> with the IPVS rules active, the requests directed to the local node work,
> but fail going to the other node. IPVS is using gate (direct server return).
>
> This has worked fine for years but my latest build using Ubuntu 12.04 isn't
> working. I've tried capturing some traffic but nothing jumps out.
>
> I've tried to make a diagram below. Any help would be appreciated. Thanks.

> Real/director1 only gets responses when the VIP traffic is sent to itself.
> When traffic is directed to the other node it fails (times out)
>
> Traffic originating from the client is balanced and directed fine.

> The standard sysctl.conf arp params are on there.
