# uname -n
orestes-tb.nevis.columbia.edu
Aha! I went to /etc/cluster/cluster.conf, and changed all the host names to the
FQDN. It works!
Master/Slave Set: AdminClone [AdminDrbd]
Masters: [ hypatia-tb.nevis.columbia.edu orestes-tb.nevis.columbia.edu ]
Lars is the man! And I am a fool for not reading this web page closely enough:
<http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Clusters_from_Scratch/ch08s02s02.html>
In the example, they just use the node name. But it clearly states to use the
output from 'uname -n' in cluster.conf. I guess on their Linux distro uname -n
returns just the node name.
Thanks!
