conf contains:

volume_name_template = volume-%s
enabled_backends=lvm1,lvm2

[lvm1]
volume_group=cinder-vg-1
volume_driver=cinder.volume.drivers.lvm.LVMISCSIDriver

volume_backend_name=lvm2

This fails because evertyhing wsa switched to self.configuration options in the driver and in this case the volume_template_name option is not included in the import optoins.

Simple fix to keep the global template name is:

    Fix missing volume_name_template flag.

    volume_template_name was converted to a self.configuration option,
    however we don't import that opt in the self.configuration changes.

    This patch switches the specifier back to the global CONF

    Fixes bug: 1199909
