Hi, This is the next DRBD MC release 0.7.5. DRBD MC, is a Java application that helps to configure DRBD and Pacemaker. You can start DRBD MC on your workstation and connect via SSH to the cluster. DRBD MC is compatible with Heartbeat 2.1.3 to the Pacemaker 1.0.9 with Corosync or Heartbeat and DRBD 8.
In this release it is possible to use resource sets without lot of crazy parenthesis with somewhat natural graphical representation, using placeholders. You can for example configure resources to start in parallel before and after a placeholder. There are also some other uses of resource sets, maybe some of them not entirely thought through yet. See how it looks like: http://oss.linbit.com/drbd-mc/img/drbd-mc-0.7.5.png To test the GUI, a test suite was implemented, making the GUI much more smoother and stable in the process. If you wonder how to test a GUI, it is possible to automate it, but it is much more laborious than to test all these command line programs. There is a robot class in Java, that moves the mouse and clicks, writes characters into combo boxes and so on. This way the GUI can be used with no hands! On the other hand any small change in the conditions during tests creates a butterfly effect and a whole test ends up in chaos. In fact a butterfly can wiggle the mouse in the evening, making the whole subsequent night of testing meaningless. Anyway the automatic GUI testing is well worth it. It turned out, that there is a class of people that tried DRBD MC when it came out, it didn't work for them for some reason or another and never looked back. There was a reason why I wanted to cal it alpha then. Now it is beta and it will most likely just work. You can get DRBD MC here: http://www.drbd.org/mc/management-console/ http://oss.linbit.com/drbd-mc/DMC-0.7.5.jar http://oss.linbit.com/drbd-mc/drbd-mc-0.7.5.tar.gz You can start it with help of Java Web-Start or you can download it and start it with "java -Xmx512m -jar DMC-0.7.5.jar" command. Make sure you use the Java from SUN. The openjdk seems to work fine for some time now, but it seems to run DRBD MC much slower than the original Java. Here are the most important changes: * improved stability * --version option * test suite implementation * don't remove dc-version etc, when storing global options * reenable VM's * fix sorting of block devices consisting of digits * implement resource sets * fix online/offline indicator * enable the "type to search" in long lists * fixes for hostnames with capital letters Rasto Levrinc -- : Dipl-Ing Rastislav Levrinc : DRBD-MC http://www.drbd.org/mc/management-console/ DRBD(R) and LINBIT(R) are registered trademarks of LINBIT, Austria. _______________________________________________ drbd-mc mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-mc
