I would then have the single node name on each, for each of the 2 PS's on the individual systems. So for this setup, you would have to trigger two stonith devices, one for each AP7900, with identical node names. Only after both succeeded would you be able to consider the node to be dead. Correct? I don't recall reading anything in the pacemaker et al documentation that would cover this case. I was under the impression that after one stonith resource is successfully invoked, the node would be considered to be offline. If so, I'd be suspicious about assuming both PDUs would get activated without further investigation and testing. (I don't think that you could consider two node names on one PDU to be equivalent to one on each of two PDUs.) Right, there's currently no way to do a simultaneous reset on two distinct fencing devices. I think that in such a case you'd also have to ensure that your stonith action is poweroff rather than reset, or your node may not actually lose power (although you could mitigate that likelihood by configuring a longer reset time in the PDU). Defining more than one stonith resource wouldn't work in this case either, because as soon as one of them reports success, the node is considered fenced. Thanks, Dejan However, while I've written RAs before, I've never looked at the stonith logic, so I could be completely out to lunch.

[Pacemaker] DRBD MC 0.8.4 / Pacemaker GUI
Hi, This is the next DRBD MC release 0.8.4. 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. Focus of this release was on performance, profiling, fixing leaks and stuff like that. Thanks to this DRBD MC went straight from being bloated and sloppy application to lightweight and lean, making the source code a textbook of concentrated good-coding practices. It turned out, that after couple of changes it is now possible to run DRBD MC as an applet without any performance or functionality loss. See here: http://oss.linbit.com/drbd-mc/img/drbd-mc-0.8.4.png It just sits in the browser and makes all this everything-must-be-web people happy. For now if you want to enable the applet functionality, you'd have to compile and sign it yourself. You can get DRBD MC here: http://www.drbd.org/mc/management-console/ http://oss.linbit.com/drbd-mc/DMC-0.8.4.jar http://oss.linbit.com/drbd-mc/drbd-mc-0.8.4.tar.gz 1. Download the DMC-0.8.4.jar file. 2. Make sure you use SUN Java not the OpenJDK 1.6. 3. Start it: java -jar DMC-0.8.4.jar 4. It connects to the cluster via SSH. DRBD MC is compatible with Heartbeat 2.1.3 to the Pacemaker 1.1.3 with Corosync or Heartbeat and DRBD 8. Here are the most important changes: * add clone-node-max meta attribute * fix defaults in IPaddr/IPaddr2 RAs * remove useless node name and DNS check in host dialog wizard * add --no-upgrade-check option * fix applying of clones * fix leaks with groups and clones * graph fixes * fix graph resizing * fix leak with DRBD resources * make it possible to run as an applet * upgrade Jung library to 2.0.1 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

Yes, the role of the second resource defaults to the role of the first. Ditto for order and actions. A bit confusing, I know. Thanks, Dejan I did it a bit different this time and I observe the same anomaly.

Because Pacemaker cannot migrate dependent resources, and because xen apparently still thinks it needs both nodes Primary for a short amount of time.

What did you try, what did you expect, and how do you determine it did not work? whenever a drbd resource gets disconnected fencing script usually define a constraint, for example: location drbd-fence-by-handler-ms_drbd_ldap ms_drbd_ldap \ rule $id=drbd-fence-by-handler-rule-ms_drbd_ldap $role=Master -inf: #uname ne xen-11 This doesn't happen if I define handler fence-peer /usr/lib/drbd/crm-fence-peer.sh or fence-peer /usr/lib/drbd/crm-fence-peer.sh -i xen_vsvn, where xen_svn is Xen resource with drbd helper, I assume, because crm-fence-peer.sh expects drbd resource to be present in the cluster configuration and it is not the case. I guess to solve this issue correctly a drbd clone is necessary, which will bring resources to Connected state and then won't freak out if both nodes are Secondary (when Xen VM is shutdown) or both nodes are Primary (when migration is in progress).

In particular, it is: hardware revision: J13 APP version 2.2.0 AOS version 3.0.3 It is running just fine (see caveat below) with the following configuration, and I can attest that it has properly stonith'd nodes many times. primitive msw stonith:apcmastersnmp \ operations $id=msw-operations \ op monitor interval=15 timeout=15 start-delay=15 \ params ipaddr=IPADDR port=161 community=COMMUNITY clone msw-clone msw \ meta clone-max=2 target-role=started (yeah, that monitor interval is probably a little quick ...) That particular cluster is getting long in the tooth: pacemaker-1.0.5-4.6.x86_64 openais-0.80.5-15.1.x86_64 The caveat is that this PDU used to work with the default implementation, however at some point someone updated the OIDs in apcmastersnmp to match newer firmware.
