Re: heartbeat

Hi Dimitri,

yes there are 4 pairs, but they are all active.  When a node fails,  the 
other one in the pair just takes everything over.
A different HA is not an option, it has to be heartbeat.  I noticed 
something called ethmonitor, I can probably notice an IB connection with 
it (it has ipoib on it)
