 * thinpool (Parameter) - Default value: `false` - Set to true to create a thin pool or to pool name to create thin volume
+* use_fs_label (Parameter) - Default value: `false` - Set to true to create and mount the filesystem with a label (e.g. `mkfs.ext4 -L foobar` and `mount LABEL=foobar /mnt`). The value is taken from the resource-title.
 * volume_group (Parameter) - The volume group name associated with this logical volume. This will automatically set this volume group as a dependency, but it must be defined elsewhere using the volume_group resource type.
