Linux Cluster Mangagement Console is a Java® application that eases the burden of managing your DRBD and Pacemaker/Corosync or Heartbeat based cluster systems.
Although this is a graphical user interface to your DRBD/Pacemaker/Corosync or Heartbeat cluster, you still need to have a good and clear understanding of the concepts of such clusters.
Before October 2011 LCMC was known as DRBD:MC. Until that time it was a LINBIT effort. Nowadays updates and releases of this software can be found on its project page at Sourceforge.
