+The ``-D (--disk-parameters)`` option allows you to set the default disk
+template parameters at cluster level. The format used for this option is
+similar to the one use by the ``-H`` option: the disk template name
+must be specified first, followed by a colon and by a comma-separated
+list of key-value pairs. These parameters can only be specified at
+cluster and node group level; the cluster-level parameter are inherited
+by the node group at the moment of its creation, and can be further
+modified at node group level using the **gnt-group**(8) command.

+ Re-synchronization rate, expressed in KiB/s
+
+data-stripes
+ Number of stripes to use for data LVs
+
+meta-stripes
+ Number of stripes to use for meta LVs
+
+disk-barriers
+ What kind of barriers to **disable** for disks. It can either assume
+ the value "n", meaning no barrier disabled, or a non-empty string
+ containing a subset of the characters "bfd". "b" means disable disk
+ barriers, "f" means disable disk flushes, "d" disables disk drains
+
+meta-barriers
+ Boolean value indicating whether the meta barriers should be
+ disabled (True) or not (False).
+
+metavg
+ String containing the name of the default LVM volume group for DRBD
+ metadata. By default, it is set to ``xenvg``. It can be overridden
+ during the instance creation process by using the ``metavg`` key of
+ the ``--disk`` parameter.
+
+disk-custom
+ String containing additional parameters to be appended to the
+ arguments list of ``drbdsetup disk``.
+
+net-custom
+ String containing additional parameters to be appended to the
+ arguments list of ``drbdsetup net``.
+
+List of parameters available for the **plain** template:
+
+stripes
+ Number of stripes to use for new LVs

The option ``--maintain-node-health`` allows one to enable/disable
automatic maintenance actions on nodes. Currently these include
automatic shutdown of instances and deactivation of DRBD devices on
