Linux Replicated High Availability Manager (also known as Linuxha.net or linuxha-net) is an open source command-line tool that allows users to create clusters for high availability applications through data replication.
Currently, clusters are limited to two nodes, but multiple applications can be hosted and failed-over between the nodes. Linux Replicated High Availability Manager uses DRBD to provide the data replication facility.
Being easy to setup and manage, and with full support for IPv6 cluster configurations, Linux Replicated High Availability Manager aims to allow system administrators to quickly deploy standard applications.
