Doc Text Feature:

Operators can now enable the run_arping feature for pacemaker managed virtual ips, so that the cluster checks for duplicate ips preemptively.

This can be accomplished by setting:

ExtraConfig:
pacemaker::resource::ip::run_arping: true


Reason:

To prevent duplicate ips in the network fabric.

Result:

Pacemaker resource will be configured like the following:

Resource: ip-172.17.3.115 (class=ocf provider=heartbeat type=IPaddr2)
Attributes: ip-172.17.3.115-instance_attributes
cidr_netmask=32
ip=172.17.3.115
run_arping=true

If a duplicate is found the following error will be logged in /var/log/pacemaker/pacemaker.log:

Sep 07 05:54:54 IPaddr2(ip-172.17.3.115)[209771]: ERROR: IPv4 address collision 172.17.3.115 [DAD]
Sep 07 05:54:54 IPaddr2(ip-172.17.3.115)[209771]: ERROR: Failed to add 172.17.3.115

With this enhancement, operators can enable the run_arping feature for Pacemaker-managed virtual IPs (VIPs), so that the cluster preemptively checks for duplicate IPs.
To do this, you must add the following configuration to the environment file:
ExtraConfig:
pacemaker::resource::ip::run_arping: true
