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. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ "If you have nothing good to say about someone, just shut up!." -- Lucky Dube
