-
-- ``devel/upload`` now works when ``/var/run`` on the target nodes is a
- symlink.
-- Disks added through ``gnt-instance modify`` or created through
- ``gnt-instance recreate-disks`` are wiped, if the
- ``prealloc_wipe_disks`` flag is set.
-- If wiping newly created disks fails, the disks are removed. Also,
- partial failures in creating disks through ``gnt-instance modify``
- triggers a cleanup of the partially-created disks.
-- Removing the master IP address doesn't fail if the address has been
- already removed.

+=================
+Ganeti 2.8 design
+=================
+
+The following design documents have been implemented in Ganeti 2.8:
+
+- :doc:`design-reason-trail`
+- :doc"`design-autorepair`
+
+The following designs have been partially implemented in Ganeti 2.8:
+
+- :doc:`design-storagetypes`
+- :doc:`design-hroller`
+- :doc:`design-query-splitting`: everything except instance queries.
+- :doc:`design-partitioned`: "Constrained instance sizes" implemented.
+- :doc:`design-monitoring-agent`: implementation of all the core functionalities
+ of the monitoring agent. Reason trail implemented as part of the work for the
+ instance status collector.

line assumes that all your nodes have secondary IPs in the
192.0.2.0/24 network, adjust it accordingly to your setup.
-.. admonition:: Debian
-
- Besides the ballooning change which you need to set in
- ``/etc/xen/xend-config.sxp``, you need to set the memory and nosmp
- parameters in the file ``/boot/grub/menu.lst``. You need to modify
- the variable ``xenhopt`` to add ``dom0_mem=1024M`` like this:
-
- .. code-block:: text
-
- ## Xen hypervisor options to use with the default Xen boot option
- # xenhopt=dom0_mem=1024M
-
- and the ``xenkopt`` needs to include the ``maxcpus`` option like
- this:
-
- .. code-block:: text
-
- ## Xen Linux kernel options to use with the default Xen boot option
- # xenkopt=maxcpus=1
-
- Any existing parameters can be left in place: it's ok to have
- ``xenkopt=console=tty0 maxcpus=1``, for example. After modifying the
- files, you need to run::
-
- $ /sbin/update-grub
-
If you want to run HVM instances too with Ganeti and want VNC access to
the console of your instances, set the following two entries in
``/etc/xen/xend-config.sxp``:
else:

+BUGS
+----
+
+The ``hail`` iallocator hasn't been updated to take networks into
+account in Ganeti 2.7. The only way to guarantee that it works correctly
+is having your networks connected to all nodegroups. This will be fixed
+in a future version.
+
COMMANDS
--------
The exist status of the command will be zero, unless for some reason
the algorithm fatally failed (e.g. wrong node or instance data).
+BUGS
+----
+
+Networks (as configured by **gnt-network**\(8)) are not taken into
+account in Ganeti 2.7. The only way to guarantee that they work
+correctly is having your networks connected to all nodegroups. This will
+be fixed in a future version.

+HAREP(1) Ganeti | Version @GANETI_VERSION@
+=========================================
+
+NAME
+----
+
+harep - Ganeti auto-repair tool
+
+SYNOPSIS
+--------
+
+**harep** [ [**-L** | **\--luxi** ] = *socket* ] [ --job-delay = *seconds* ]
+
+**harep** \--version
+
+DESCRIPTION
+-----------
+
+harep is the Ganeti auto-repair tool. It is able to detect that an instance is
+broken and to generate a sequence of jobs that will fix it, in accordance to the
+policies set by the administrator.
+
+OPTIONS
+-------
+
+The options that can be passed to the program are as follows:
+
+-L *socket*, \--luxi=*socket*
+ collect data via Luxi, optionally using the given *socket* path.
+
+\--job-delay=*seconds*
+ insert this much delay before the execution of repair jobs to allow the tool
+ to continue processing instances.
