A new tripleo_multipathd role is responsible for preparing and configuring an overcloud node to run multipathd in a container. - Host prep tasks ensure any existing multipathd service is disabled on the host. - /etc/multipath.conf configuration is controlled via ansible variables supplied by tripleo's OS::TripleO::Services::Multipathd service. - The multipathd container is restarted whenever the configuration changes.
