Linux Replicated High Availability Manager 1.4.2 (DRBD 8.2 based branch)

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. License: GNU General Public License v2 Changes:
Many minor and major bugs have been fixed. The administrators guide documentation has been updated to reflect these changes and several other improvements.
