[DRBD-announce] DRBD MC 0.9.4 / Pacemaker GUI

Hi,

This is the next DRBD:MC release 0.9.4. DRBD:MC is DRBD, Pacemaker and
Cluster Virtual Manager GUI.

The commands in DRBD 8.4 (the replication software) have changed a lot, but
you don't have to worry about it if you use DRBD:MC, except some fields got
shuffled around and there's something called volumes in between.


I've noticed that OpenJDK 6 is getting better for some time. Not only the
Java application starts with it now, after minimum of changes it was running,
without blowing up the computer.

Although things fix by themselves occasionally, it turned out that making a
workaround for one Java version on one platform breaks something on other
platform, causing a combinatorial explosion of breakages, workarounds a fixes.
In short I've been for couple of days I've been in a place, we call the Java
hell.

Now it works perfectly with OpenJDK 6, but It is still recommended to run
it with SUN Java, since OpenJDK is a bit slow in comparison.

1. You don't need Java on the cluster servers only on your desktop.
2. Download the DMC-0.9.4.jar file.
3. Start it: java -jar DMC-0.9.4.jar, or click on the file.
4. It connects to the cluster via SSH.
5. If you use it without DRBD, you have to click "Skip" button on couple of
places.
6. It is recommended to use it with SUN Java.

DRBD:MC is compatible with Heartbeat 2.1.3 to the Pacemaker 1.1.5 with
Corosync or Heartbeat and DRBD 8.
