The Linux Replicated High Availability Manager (Linuxha.net) allows the creation of clusters for application high availability through data replication. Currently, clusters are limited to two nodes, but multiple applications can be hosted and failed-over between the nodes. The software uses DRBD to provide the data replication facillity.
|Operating Systems||POSIX Linux|
Release Notes: This release supports the latest version of DRBD for data replication, the latest 3.x kernels, and the use of IPv6 in applications and cluster infrastructure. There were many minor improvements and fixes.

Release Notes: A large number of changes, fixes, and enhancements have been made. The documentation has been completely updated and revised. Network bonding is supported for more reliable networking. IP fail-over handling was improved. Single node cluster functionality was improved. Cluster partitioning support was improved. The latest versions of DRBD are supported. Heartbeat daemon functionality was improved. SSH handling was improved.
Release Notes: Introduction of support for applications using direct device files rather than file systems. This has been added to better support virtual machines as clustered applications. Inclusion of a new command that will allow virtual machines that support live migration to be moved between cluster nodes without taking the application down at any point.
