This is the next DMC release 0.9.7. DMC is Pacemaker, Cluster Virtual Manager
and Storage/DRBD GUI written in Java.

The LVM plugins are now normal part of the GUI in the "Storage" view, where
you can create, delete physical volumes, volume groups, logical volumes,
resize them and create snapshots in the (whole) cluster. Goodbye command

Some issues with KDE/Compiz were fixed or at least they were made much less
likely to appear. Most notably blank windows. Personally I haven't use KDE
since the 4.0 came out and just assumed that everything worked at least as
anything else on the KDE, but it didn't.

Some issues with applets were fixed as well, so go ahead and use your browser
for everything. :)



You can get DRBD:MC here:

1. You don't need Java on the cluster servers only on your desktop.
2. Download the DMC-0.9.7.jar file.
3. Start it: java -jar DMC-0.9.7.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
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.
