Hello,
I am an absolute beginner trying to setup our first HA Cluster.
So far I have been working with the "Pacemaker 1.1 Clusters from
Scratch" Guide wich worked for me perfectly up to the Point where I need
to install and configure STONITH.
Curerent Situation is:2 Ubuntu Server as the cluster. Both of those
Servers are virtual machines running on 2 Centos KVM Hosts.
Those are the devices or ressources we can use for a STONITH
implementation. In this and other guides I do read a lot about external
devices and in the "pcs stonith list" there are some XEN but sadly I
cannot find anything about KVM. At this point I am stumped and have no
clue in how to proceed, I am not even sure what further inforamtion I
shopuld provide that would be useful for giving advise?
The current pcs status is:
# pcs status
Cluster name: pacemaker_cluster
WARNING: corosync and pacemaker node names do not match (IPs used in setup?)
Stack: corosync
Current DC: server2ubuntu1 (version 1.1.18-2b07d5c5a9) - partition with
quorum

I have researched the shown dlm Problem but everything I have found says
that configuring STONITH would solve that issue.
Could please someone advise on how to proceed?
Thank you in advance!
Kind regards
Stefan Schmitz
