Donate to the LCMC.

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.

Download and Instructions

  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-2.0.1.jar file or download a package for your OS/distro here: Sourceforge
  3. Start it: java -jar LCMC-2.0.1.jar, or run "lcmc" if you installed a package.
  4. You can specify more available memory: java -jar -Xmx1024m LCMC-2.0.1.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.
