A good way to test fencing is to crash the OS with 'echo c >
/proc/sysrq-trigger', which causes an immediate segfault. The only
recovery is a reboot, so it's excellent for simulating a hung node.
Make sure, too, that you've hooked DRBD's fencing into pacemaker with
'fencing resource-and-stonith;' and using the crm-{un,}fence-peer.sh
{un,}fence-handlers.
If these are bare-iron nodes, also test by pulling the power out of the
node entirely while it was running. If you can pass both of these tests,
you will have simulated most all possible node failure modes (I say
'most' because it is impossible to think of everything :) ).

[ClusterLabs] lrmd segfault
Hi All. We have the heterogeneous corosync/pacemaker cluster of 5 nodes: 3 SL7(Scientific linux) and 2 SL6. SL7 pacemaker installed from a standard repo (corosync - 2.3.4, pacemaker - 1.1.13-10), SL6 build from sources (same version). The cluster not unified, some nodes have RA which other do not have. crmsh used for management. SL6 nodes runs surprisingly smoothly, but SL7 steady segfaulting in the exactly same place.

Hi everyone! The last time we had an HA summit was in 2015, and the intention then was to have SUSE arrange the next meetup in the following year. We did try to find a date that would be suitable for everyone, but for various reasons there was never a conclusion and 2016 came and went. Well, I'd like to give it another try this year! This time, I've already got a proposal for a place and date: September 7-8 in Nuremberg, Germany (SUSE main office). I've got the new event area in the SUSE office already reserved for these dates. My suggestion is to do a two day event similar to the one in Brno, but I am open to any suggestions as to format and content. The main reason for having the event would be for everyone to have a chance to meet and get to know each other, but it's also an opportunity to discuss the future of Clusterlabs and the direction going forward.

Re: [ClusterLabs] Corosync maximum nodes
Hello! I'm very sorry to disturb you with such question but I can't find information if there is maximum nodes' limit in corosync? I've found a bug report https://bugzilla.redhat.com/show_bug.cgi?id=905296#c5 with "Corosync has hardcoded maximum number of nodes to 64" but it was posted 4 years ago.. This limit is gone in 2.x, but it doesn't mean corosync is able to handle much more without finetuning. If anybody knows how many nodes I can add to future HA cluster? http://lists.clusterlabs.org/pipermail/users/2017-January/004764.html But honestly, as Chrissie told, pacemaker-remote is usually better way to go (as long as you are not planning to use dlm on all nodes).
