Hello,
I'm trying to find a good solution to properly shutdown a DRBD
(master/slave) cluster in case of outages. The problem, at least for me,
is that if you simply shutdown one node, when it comes back in 99% on
the cases you'll end up with split brain scenarios. So for me the proper
logic in cas

Currently you can setup a basic cluster (including configuring corosync

Nice guide. You should consider adding it to the wiki.

You should also be able to do pcmk_host_list=fail1,fail2 to avoid the

In addition to some updates for 1.1.8, the documentation at
http://www.clusterlabs.org/doc/ now comes in two flavours.
Clusters from Scratch (and to a lesser extent Pacemaker Explained) now come in
"pcs" and "crmsh" editions.
So regardless of which admin tool you're a fan of, we've got you cover

We use keepalived instead of ldirectord for managing our load
balancers, partly for historical reasons, and partly because it has a
