# neutron-ha-tool is run on a single node at a time, i.e. in
# active/passive mode. So we use this state file to keep
# track of whether it's active on the current node, and if
# Pacemaker does a probe on a node where it's not active, we
# skip the l3-agent check and always return OCF_NOT_RUNNING,
# otherwise we'd get messages from pengine like:
#
# error: Resource neutron-ha-tool (ocf::neutron-ha-tool) is active on
# 2 nodes attempting recovery
# warning: See http://clusterlabs.org/wiki/FAQ#Resource_is_Too_Active
# for more information.
#
# and Pacemaker could attempt unnecessary recovery according to the
# value of the cluster-wide "multiple-active" option.
