+# This define manages the creation of a logical volume using the `lvm::volume` definition.
+#
+# Parameters:
+#   $ensure   - Ensure whether the logical volume is present or not. Defaults to 'present'.
+#   $vg       - Volume group name. No default.
+#   $pv       - Physical volume, typically the disk or partition device path. No default.
+#   $fstype   - Filesystem type for the logical volume. Defaults to 'ext3'.
+#   $size     - Size of the logical volume. undef = 100%FREE. Changing $size to cause a resize.
