I've tried to reproduce this problem on Fuel 6.0.1 ISO #239.

I enterd password with dollar (Q$wer!123), added one controller node to the cluster and
started deployment process.

Deployment process finished successfully, but I ended up with inoprable cluster.
nova-compute service fail to start on controller, because it cannot interpolate variable $wer.

Pacemaker marks nova-compute service as 'Started', but actually it is constantly restarting and
it does not appear in 'nova service-list' output.  There are no available hypervisors in OpenStack
to operate.  So I think we should raise severity for 6.0.1 to High.
