The LCMC is a GUI application that configures, manages and visualizes high-availability clusters. Specifically it manages clusters that use one or more of these components: Pacemaker, Corosync, Heartbeat, DRBD, KVM, XEN and LVM.

1. You don't need Java on the cluster servers only on your desktop. (you may need to install Perl on the servers)
2. Download the LCMC-1.7.9.jar file or download a package for your OS/distro here: Sourceforge
3. Start it: java -jar LCMC-1.7.9.jar, or run "lcmc" if you installed a package.
4. You can specify more available memory: java -jar -Xmx1024m LCMC-1.7.9.jar
5. It connects to the cluster via SSH.
6. If you use it without DRBD, you have to click "Skip" button on couple of places.
