# == Define: tripleo::pacemaker::resource_restart_flag

# resource needs restarting (usually to pick up config changes after
# they've been written on all nodes).
#
# === Parameters
#

#   The resource name in Pacemaker to restart. If it's a cloned
#   resource, the name should include the '-clone' part.
