This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 9.10) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Ubuntu 9.10 as well) will be able to access the storage [...]
