I apologize; the site I was thinking of is using Sun Cluster with the
data on a SAN. For some reason I thought it was DRBD with Heartbeat; I'm
not sure if it was ever that, or if someone had just mentioned it...

I really thought I knew someone that was doing that, though. I hope they
are reading this list and will speak up, because I apparently don't
remember who you are :)

If they have connection troubles before you even do any failover or
anything, that may not have anything to do with the HA setup. Before
failover, it shouldn't be too different from a normal fileserver.
