Hi List,
I want a scenario where I have two servers that appear as one
server (one IP) to the outside world, with both servers having
*exactly* the same data and services. So in case one server falls
into a pond somehow, I woun't even loose a ping from my clients.
Any help or pointers as to where I can start digging for
information? the web speaks about pacemaker, heartbeat, drbd, some
even talk about xen with remus, again a flood of information,
confusing at best. I want a simple clean solution that works great
with debian. I'd prefer a bare metal approach with
services/systems running to make sure my setup is always available
but transparent to the various client services connecting to it,
and also transparent to the services running inside the box(es).
Each box will hold its on copy of RAIDed data
HA is service based, IIRC. Then again, you'll definately need a shared storage. It is not possible to have HA when each server has its own storage. You need to narrow down to the services which you'd like to make HA and see how they work with shared storage.
Just my 2 cents worth of advise.
