building a cluster

[rAlhidawi]

Does someone know how to build a cluster? I mean from where to go?!

I need to build a cluster from 16 devices but I don't know the clear step to begin?

I don't have any experience with setting up a text-book cluster but I have built a loadbalanced system with failover using DRBD and heartbeat. Probably not exactly what you are looking for. You need to do some research first to pin down exactly what you want to do with the cluster and how it will be used before you can just start building it.

Here are a few links to that will get yo going:

I am very interested in this subject too rAlhidawi! I have a lot of fairly powerful computers hanging around, and I would love to put them to use (other than as file servers). Let us know if you find anything!

If you want to replicate storage between servers, like a hardware failover option look into DRBD. I have it running on a pair of web servers with great success. I can perform all my changes on one server and they are automatically replicated to the other. I can disconnect either machine from the network and work on it and the other takes over. Its really slick.
