DRBD

Distributed Replicated Block Device (DRBD) is a distributed replicated storage system for the Linux platform. It mirrors block devices between multiple hosts, functioning transparently to applications on the host systems. This replication can involve any type of block device, such as hard drives, partitions, RAID setups, or logical volumes.
