[DRBD-announce] DRBD Management Console 0.5.0

Hi,

This is the next DRBD-MC beta release 0.5.0. DRBD-MC is a Java GUI that
helps to configure DRBD/Pacemaker/Corosync/Openais/Heartbeat clusters.

You can get DRBD-MC here:

http://www.drbd.org/mc/management-console/

http://oss.linbit.com/drbd-mc/drbd-mc-0.5.0.tar.gz
http://oss.linbit.com/drbd-mc/DMC-0.5.0.jar

You can start it with help of Java Web-Start or you can download it and
start it with "java -jar DMC-0.5.0.jar" command.

One of the new great features in this release is the ptest integration in
the GUI. It's something like What-If machine or a ptest before commit, if
you are CRM shell fan, but without hassle of finding out about ptest and
making the sense of its output. It works with Pacemaker (not older
Heartbeats) and anytime you are about to do something, you will see what
will happen. This tests are executed as you hover with your mouse pointer
over some buttons or pull-down menus and you see what will happen in the
graph and in the tooltips. It is kind of difficult to describe because it is
entirely a new GUI element I've just invented and I hope everyone will love
it, not hate it.

Similarly any time you do some change in DRBD config a dry-run is performed
first and see if something bad is about to happen, for example a full-sync.

In this release a VNC viewer for VirtualDomain resource was added. Well,
LINBIT forced me to do it, but it is actually quite neat.

Some people ask about DRBD-MC documentation, there definitely will be one,
but at the moment DRBD-MC develops too fast and it would be quite impossible
to keep the documentation up-to-date, just like what happened once or twice
with Pacemaker documentation. :)

See some new features in the screenshot:
