# == Class: tripleo::profile::base::pacemaker
#
# Pacemaker profile for tripleo
#
# === Parameters
#
# [*step*]
# (Optional) The current step in deployment. See tripleo-heat-templates
# for more details.
# Defaults to hiera('step')
#
# [*pcs_tries*]
# (Optional) The number of times pcs commands should be retried.
# Defaults to hiera('pcs_tries', 20)
#
# [*remote_short_node_names*]
# (Optional) List of short node names for pacemaker remote nodes
# Defaults to hiera('pacemaker_remote_short_node_names', [])
#
# [*remote_node_ips*]
# (Optional) List of node ips for pacemaker remote nodes
# Defaults to hiera('pacemaker_remote_node_ips', [])
#
# [*remote_authkey*]
# (Optional) Authkey for pacemaker remote nodes
# Defaults to undef
#
# [*remote_reconnect_interval*]
# (Optional) Reconnect interval for the remote
# Defaults to hiera('pacemaker_remote_reconnect_interval', 60)
#
# [*remote_monitor_interval*]
# (Optional) Monitor interval for the remote
# Defaults to hiera('pacemaker_monitor_reconnect_interval', 20)
#
# [*remote_tries*]
# (Optional) Number of tries for the remote resource creation
# Defaults to hiera('pacemaker_remote_tries', 5)
#
# [*remote_try_sleep*]
# (Optional) Number of seconds to sleep between remote creation tries
# Defaults to hiera('pacemaker_remote_try_sleep', 60)
#
# [*cluster_recheck_interval*]
# (Optional) Set the cluster-wide cluster-recheck-interval property
# If the hiera key does not exist or if it is set to undef, the property
# won't be changed from its default value when there are no pacemaker_remote
# nodes. In presence of pacemaker_remote nodes and an undef value it will
# be set to 60s.
# Defaults to hiera('pacemaker_cluster_recheck_interval', undef)
