Comment 1 for bug 1673579

On zesty it all works without errors, namely:

Install Pacemaker packages:
sudo apt-get install pcs

Set the password for the default user:
sudo passwd hacluster

#To clear files
sudo pcs cluster destroy

sudo pcs cluster auth pacemaker-1 pacemaker-2 -u hacluster -p haclusterpassword
sudo pcs cluster setup --name hacluster pacemaker-1 pacemaker-2

(And start doesn't error out)
