[DRBD-announce] DRBD MC 0.8.4 / Pacemaker GUI

Hi,

This is the next DRBD MC release 0.8.4. DRBD MC is a Java application that
helps to configure DRBD, Pacemaker, VMs or any combination of them. It uses
SSH to connect to the cluster from a desktop computer.

Focus of this release was on performance, profiling, fixing leaks and stuff
like that. Thanks to this DRBD MC went straight from being bloated and

sloppy application to lightweight and lean, making the source code a
textbook of concentrated good-coding practices.

It turned out, that after couple of changes it is now possible to run DRBD
MC as an applet without any performance or functionality loss. See here:

It just sits in the browser and makes all this everything-must-be-web people
happy. For now if you want to enable the applet functionality, you'd have to
compile and sign it yourself.

You can get DRBD MC here:

http://oss.linbit.com/drbd-mc/drbd-mc-0.8.4.tar.gz

1. Download the DMC-0.8.4.jar file.
2. Make sure you use SUN Java not the OpenJDK 1.6.
3. Start it: java -jar DMC-0.8.4.jar
4. It connects to the cluster via SSH.

DRBD MC is compatible with Heartbeat 2.1.3 to the Pacemaker 1.1.3 with
Corosync or Heartbeat and DRBD 8.
