[Linux-HA] heartbeat with only 1 NIC per server?

[Rudi Ahlers]

Hi all

I hope someone can assist me with this one. I previously (almost a year 
ago) setup heartbeat on 2x Suse 9.3 machines, where each server had a 
wireless NIC & a onboard NIC. The network ran on the wireless NIC's, and 
I then used the onboard NIC's with a crossover cable to monitor heartbeat.

Recently, we took out the wireless network, and put in a 8 port 10/100 
switch to run eveything on. So, each server now only has 1 NIC. The 
wireless gave us too many problems, and getting working cards was a 
problem. To put it differently, the client is 700KM away, and not IT 
literate, so we had to fedex the wireless NIC to them, and try and make 
it work over the phone. Bottomline, running a normal CAT5 LAN is less 
error prone.

So, to get back to the question. How stable / safe / redundant is it to 
run heartbeat over the same NIC's as the LAN?
If server 1 use IP 192.168.0.5, server 2 use 192.168.0.6 & tell 
heartbeat to server 192.168.0.3 on the LAN, will this work well enough?
