+Distributed Replicated Block Device - DRBD
+==========================================
+
+Description
+===========
+
+ DRBD is a shared-nothing, synchronously replicated block device. It
+ is designed to serve as a building block for high availability
+ clusters and in this context, is a "drop-in" replacement for shared
+ storage. Simplistically, you could see it as a network RAID 1.
+
+ Please visit https://www.drbd.org to find out more.
