GlusterFS
GlusterFS is a distributed filesystem. It has built in redundancy, so it is possible to run two servers which automatically replicate files between the servers. If one server goes down, the other just takes over. Once it comes up again, files are automatically replicated. Here we will use GlusterFS as a redundant network mounted file storage.
For the sport of it, we will configure 4 GlusterFS servers.
Configure the servers, then the client. Once completed continue by setting up encryption.
