High-Availability Storage with GlusterFS on CentOS 7 – Mirror across two storage servers
This tutorial shows how to set up a high-availability storage with two storage servers (CentOS 7.2) 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 (CentOS 7.2 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes.
