Share a private IP between 2 linodes
Im building a galera cluster that I want to sit behind haproxy for load balancing. I don't want haproxy to be a SPOF so want to make it HA with keepalived.
I'll need a second private IP on one of the haproxy machines to start so I can use it as a floating address for keepalived as far as im aware.
How can I set that second private ip to shared across the 2 haproxy servers? When I go to the IP Sharing settings under network configuration the private IP addressed dont seem to be available.
This is possible, though private IP failover is only available on some of our data centers, specifically in our non-NGN (Next Generation Network) data centers. That said, we do plan on bringing this feature to NGN data centers in the future.
A list of current non-NGN data centers:
For more information on what NGN is, the following post provides details:

If your Linode is not in one of the current non-NGN data centers, you can migrate the Linode:

Whoops - thanks for catching that, @andysh. It is indeed not an NGN data center yet. Sorry to get your hopes up.

Hahaha you got me all excited. Never mind, just means more to look forward to :)
