different than "xenvg" for Ganeti to use when creating instance
disks. This volume group must have the same name on all nodes. Once
the cluster is initialized this can be altered by using the
-**modify** command. If you don't want to use lvm storage at all use
-the ``--no-lvm-storage`` option. Once the cluster is initialized

+
+If you don't want to use lvm storage at all use
+the ``--enabled-disk-template`` option to restrict the set of enabled
+disk templates. Once the cluster is initialized
you can change this setup with the **modify** command.
The ``--master-netdev`` option is useful for specifying a different
generated. The prefix must be specified in the format ``XX:XX:XX`` and
the default is ``aa:00:00``.
-The ``--no-lvm-storage`` option allows you to initialize the
-cluster without lvm support. This means that only instances using
-files as storage backend will be possible to create. Once the
-cluster is initialized you can change this setup with the
-**modify** command.
-
The ``--no-etc-hosts`` option allows you to initialize the cluster
without modifying the /etc/hosts file.
The ``--specs-...`` and ``--ipolicy-...`` options specify the instance
policy on the cluster. The ``--ipolicy-bounds-specs`` option sets the
minimum and maximum specifications for instances. The format is:
-min:*param*=*value*,.../max:*param*=*value*,... The
+min:*param*=*value*,.../max:*param*=*value*,... and further
+specifications pairs can be added by using ``//`` as a separator. The
``--ipolicy-std-specs`` option takes a list of parameter/value pairs.
For both options, *param* can be:
- ``--ipolicy-spindle-ratio`` limits the instances-spindles ratio
- ``--ipolicy-vcpu-ratio`` limits the vcpu-cpu ratio
+All the instance policy elements can be overridden at group level. Group
+level overrides can be removed by specifying ``default`` as the value of
+an item.
+
+The ``--drbd-usermode-helper`` option can be used to specify a usermode
+helper. Check that this string is the one used by the DRBD kernel.
