The puppet and ansible tasks for deploying the Multipathd service have been moved to a new tripleo_multipathd ansible role. THT uses that role passing in parameter values via ansible variables. Two new THT parameters are supported: - MultipathdCustomConfigFile provides a way for the user to specify a custom multipath.conf file. This makes it easier for the user to manage custom settings that are unique to their deployment, such as vendor specific hardware tuning. - MultipathdSkipKpartx provides a means for overriding multipathd's default behavior whereby it automatically creates disk partitions on multipath devices. Partitions should be managed by VM servers accessing the device, not by the overcloud host itself.
