Actually I want to do it like ipfail: if node A cannot reach
the ping_nodes, check if node B can, if it cannot, then
leave services running on node A.  if node B can
reach the ping_nodes then failover.
Only, that I'm not checking with ping but the physical
link, and so I need a way to get the information from
the other node ("link status").  So have to figure out
another way.

I see, are there any replacements for the hb_standby and hb_takeover
scripts in such installations?

This is what ipfail uses, maybe I have to take a closer look.
