This is the next DRBD MC beta release 0.8.2. 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.
In this minor release couple of minor enhancements were implemented and
minor issues were fixed.
Now it is possible to specify location according the pingd results. At the
moment, the "on host with most connections" and "stop on host with no
connection" can be chosen. Let me now if there are some other uses for
The gathering information from servers has been optimized, fixed and
tuned, so that it needs much less CPU on the servers then before.
You can get DRBD MC here:
You can download it and start it with "java -jar DMC-0.8.2.jar" command or
you can use Java Webstart. First of all, please don't run it on one node
with X forwarding, but on the desktop.
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. With this so-called fully compatible Java version it runs slow,
experiences random errors or may even hang.
DRBD MC is compatible with Heartbeat 2.1.3 to the Pacemaker 1.1.2 with
Corosync or Heartbeat and DRBD 8.
