# This playbook purges Ceph
# It removes: packages, configuration files and ALL THE DATA
#
# Use it like this:
# ansible-playbook purge-cluster.yml
# Prompts for confirmation to purge, defaults to no and
# doesn't purge the cluster. yes purges the cluster.
#
# ansible-playbook -e ireallymeanit=yes|no purge-cluster.yml
# Overrides the prompt using -e option. Can be used in
# automation scripts to avoid interactive prompt.
