This is the next DRBD MC release 0.8.12. DRBD MC is DRBD, Pacemaker and
Virtual Manager GUI.

This is a minor release that focuses on fixing bugs and doing what is
expected, but don't worry, it's not self-aware yet.

To keep people from command line longer, there's now start/stop Heartbeat
option in host popup menus, or start/stop Corosync if this is what you have. 

To do what is right, migrating away a DRBD master/slave resource now works
so that DRBD is not stopped but stays slave.

To make more and more options available, the group attributes "collocated"
and "ordered" were added. On the other hand these options are an abomination 
according to Beekhof, and shouldn't be used, so they are hidden in the
abomination section, I mean advanced section.

You can get DRBD MC here:


1. You don't need Java on the cluster servers only on your desktop. 
2. Download the DMC-0.8.12.jar file.
3. Make sure you use SUN Java not the OpenJDK 1.6.
4. Start it: java -jar DMC-0.8.12.jar
5. It connects to the cluster via SSH.
6. If you use it without DRBD, you have to click "Skip" button on couple of

DRBD MC is compatible with Heartbeat 2.1.3 to the Pacemaker 1.1.4 with
Corosync or Heartbeat and DRBD 8.
