Hi, This is the next DRBD MC beta release 0.7.7. 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 1.1.2 with Corosync or Heartbeat and DRBD 8.
There are not many new features, this being vacation time and all, but there are some fixes, that it may be worth to upgrade and it happens that DRBD MC is the easiest to upgrade application ever. Orphaned resources are now shown, so if all of the sudden many orphan resources show up in the GUI, they are nothing to be worry about, they can be removed or left alone. For some reason removing may not work with recent versions of Pacemaker with Heartbeat, but it works always with Pacemaker on Corosync. If you are hit by this, ignore it simply, they will disappear after next Heartbeat+Pacemaker restart. More seriously in the version 1.2.5 corosync -v fills up shared memory. This was fixed before and after this version. Unfortunately DRBD MC checks if version of Corosync changed every minute (it is unlikely but possible) and Corosync 1.2.5 is the version that Andrew Beekhof likes to build and thus it is very popular. DRBD MC has now a workaround for this Corosync version. You can get DRBD MC here: http://www.drbd.org/mc/management-console/ http://oss.linbit.com/drbd-mc/DMC-0.7.7.jar http://oss.linbit.com/drbd-mc/drbd-mc-0.7.7.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-0.7.7.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. But first of all, please don't run it on one node with X forwarding, but on the desktop. Here are the most important changes: * workaround for Corosync 1.2.5 leaking shm with -v option * fix standby command so that it works with sudo * move "remove all services" to the advanced mode * disable menus in DRBD view, for resources that are managed by CRM * add support file for Fedora 13 and Opensuse 11.3 * show orphaned resources * when new DRBD device was created, reload filesystem comboboxes * save node colors in the graph * fix network info * remove kex timeout, that causes ssh library to hang * fix host scores bug with upper-cased hostnames * allow removing of new group services * accept +INFINITY scores Rasto Levrinc -- : Dipl-Ing Rastislav Levrinc : DRBD-MC http://www.drbd.org/mc/management-console/ : DRBD/HA support and consulting http://www.linbit.com/ DRBD(R) and LINBIT(R) are registered trademarks of LINBIT, Austria. _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker
