[DRBD-announce] DRBD MC 0.7.9 / Pacemaker GUI

[Rasto Levrinc]

Hi,

This is the next DRBD MC beta release 0.7.9. DRBD MC, is a Java application 
that helps to configure DRBD and Pacemaker. You can start DRBD MC on your 
workstation and connect to the cluster via SSH. DRBD MC is compatible with 
Heartbeat 2.1.3 to the Pacemaker 1.1.2 with Corosync or Heartbeat and DRBD 
8.

It works with SUN Java 6 and OpenJDK 7. It does not work good with OpenJDK 
1.6 and this is probably what you have if you have OpenJDK installed as Java 
at the moment. With OpenJDK 1.6, the so-called fully compatible Java 
version, it runs slow, experiences random errors or may even hang. Good news 
is, that this problem will disappear in the future by itself. For now you 
need to install the SUN Java, that comes with your distribution.

In this release couple of stability issues and annoyances were fixed. The 
VMs manager part of the program was further developed, so that now it is 
possible to add new disks and network interfaces to the virtual machines and 
modify them.
