Windows (CIFS) fileshares using GlusterFS and CTDB for Highly available data
This tutorial will walk through the setup and configuration of GlusterFS and CTDB to provide highly available file storage via CIFS. GlusterFS is used to replicate data between multiple servers. CTDB provides highly available CIFS/Samba functionality.
