Consistency groups
==================

Consistency groups enable you to create snapshots from multiple file system
shares at the same point in time. For example, a database might place its
tables, logs, and configuration on separate shares. To restore this database
from a previous point in time, it makes sense to restore the logs, tables, and
configuration together from the exact same point in time.
Shared File system allows you to create a snapshot of the consistency group and
restore all shares that were associated with the consistency group by creating
a consistency group from a snapshot.
The Shared File System service allows you to create a snapshot of the
consistency group and restore all shares that were associated with a
consistency group.

The **consistency groups and snapshots** are realized as an
**experimental** Shared File Systems API. Contributors can change or remove
the experimental part of the Shared File Systems API without maintaining
backward compatibility. The experimental API has

General concepts

General concepts **to create file share**, you need to:
As general concepts, to create a file share and access it you need to:
#. To create a share, use :command:`manila create` command and
specify the required arguments: the size of the share and the Shared File
Systems protocol (``NFS``, ``CIFS``, ``GlusterFS``, or ``HDFS`` are
supported).
specify the required arguments: the size of the share and the shared file
system protocol. ``NFS``, ``CIFS``, ``GlusterFS``, or ``HDFS`` share file
system protocols are supported.
#. You can also optionally specify the share network and the share type.
#. Use the :command:`manila create` command to create a share. This command
does the following things:
#. After the share becomes available, use the :command:`manila show` command
to get the share export location.
* If there is no available share servers, the Shared File Systems service
service will launch new instance from service image, attach it to service
network and register it as a new share server.
#. After getting the share export location, you can create an
:ref:`access rule <access_to_share>` for the share, mount it and work with
files on the remote file system.
* Creates new volume of required size and attaches it to the service
instance.
There are big number of the share drivers created by different vendors in the
Shared File Systems service. As a Python class, each share driver can be set
for the :ref:`back end <shared_file_systems_multi_backend>` and run in the back
end to manage the share operations.
* The NFS service on service instance is configured to use attached volume
and expose NFS share.
Initially there are two driver modes for the back ends:
#. After share becomes available, use the :command:`manila show` command
to get the share endpoint.
* no share servers mode
* share servers mode
In the example to create a share, the default share type and the
existing already share network are used.
Each share driver supports one or two of possible back end modes that can be
configured in :file:`manila.conf` file. The configuration option
``driver_handles_share_servers`` in :file:`manila.conf` file sets the share
servers mode or no share servers mode, and defines the driver mode for share
storage life cycle management:
.. note::
There is no default share type just after you starting manila as the
administrator. See :ref:`shared_file_systems_share_types` to
create the default share type. To create a share network, use
:ref:`shared_file_systems_share_networks`.
+------------------+-------------------------------------+--------------------+
| Mode | Config option | Description |
+==================+=====================================+====================+
| no share servers | driver_handles_share_servers = False| An administrator |
| | | rather than a share|
| | | driver manages the |
| | | bare metal storage |
| | | with some net |
| | | interface instead |
| | | of the presence of |
| | | the share servers. |
+------------------+-------------------------------------+--------------------+
| share servers | driver_handles_share_servers = True | The share driver |
| | | creates the share |
| | | server and manages,|
| | | or handles, the |
| | | share server life |
| | | cycle. |
+------------------+-------------------------------------+--------------------+
It is :ref:`the share types <shared_file_systems_share_types>` which have the
extra specifications that help scheduler to filter back ends and choose the
appropriate back end for the user that requested to create a share. The
required extra boolean specification for each share type is
``driver_handles_share_servers``. As an administrator, you can create the share
types with the specifications you need. For details of managing the share types
and configuration the back ends, see :ref:`shared_file_systems_share_types` and
:ref:`shared_file_systems_multi_backend` documentation.
You can create a share in two described above modes:
* in a no share servers mode without specifying the share network and
specifying the share type with ``driver_handles_share_servers = False``
parameter. See subsection :ref:`create_share_in_no_share_server_mode`.
* in a share servers mode with specifying the share network and the share
type with ``driver_handles_share_servers = True`` parameter. See subsection
:ref:`create_share_in_share_server_mode`.
.. _create_share_in_no_share_server_mode:
Create a share in no share servers mode
---------------------------------------
To create a file share in no share servers mode, you need to:
#. To create a share, use :command:`manila create` command and
specify the required arguments: the size of the share and the shared file
system protocol. ``NFS``, ``CIFS``, ``GlusterFS``, or ``HDFS`` share file
system protocols are supported.
#. You should specify the :ref:`share type <shared_file_systems_share_types>`
with ``driver_handles_share_servers = False`` extra specification.
#. You must not specify the ``share network`` because no share servers are
created. In this mode the Shared File Systems service expects that
administrator has some bare metal storage with some net interface.
#. The :command:`manila create` command creates a share. This command does the
following things:
* The :ref:`manila-scheduler <shared_file_systems_scheduling>` service will
find the back end with ``driver_handles_share_servers = False`` mode due
to filtering the extra specifications of the share type.
* The shared is created using the storage that is specified in the found
back end.
#. After the share becomes available, use the :command:`manila show` command
to get the share export location.
In the example to create a share, the created already share type named
``my_type`` with ``driver_handles_share_servers = False`` extra specification
is used.

------------------------------------
To create a file share in share servers mode, you need to:
#. To create a share, use :command:`manila create` command and
specify the required arguments: the size of the share and the shared file
system protocol. ``NFS``, ``CIFS``, ``GlusterFS``, or ``HDFS`` share file
system protocols are supported.
#. You should specify the :ref:`share type <shared_file_systems_share_types>`
with ``driver_handles_share_servers = True`` extra specification.
#. You should specify the
:ref:`share network <shared_file_systems_share_networks>`.
#. The :command:`manila create` command creates a share. This command does the
following things:
* The :ref:`manila-scheduler <shared_file_systems_scheduling>` service will
find the back end with ``driver_handles_share_servers = True`` mode due to
filtering the extra specifications of the share type.
* The share driver will create a share server with the share network. For
details of creating the resources, see the `documentation <http://docs.
openstack.org/developer/manila/devref/index.html#share-backends>`_ of the
specific share driver.
#. After the share becomes available, use the :command:`manila show` command
to get the share export location.
In the example to create a share, the default share type and the already
existing share network are used.

The Shared File Systems service architecture defines an abstraction layer for

of integration approaches with the network services that are available with
OpenStack.

share service with specified driver works in mode, when a share driver manages
life cycle of share servers on its own. This behavior is defined by a flag
``driver_handles_share_servers`` in share service configuration. When
``driver_handles_share_servers`` is set to ``True``, a share driver will be
called to create share servers for shares using information provided within a
share network. This information will be provided to one of the enabled network
plugins that will handle reservation, creation and deletion of network
plug-ins that will handle reservation, creation and deletion of network
resources including IP addresses and network interfaces.

There are three different network plugins and five python classes in Manila:
There are three different network plug-ins and five python classes in the
Shared File Systems service:
1. Network plugin for using the OpenStack networking project `Neutron`. It
allows one to use any network segmentation that Neutron supports. It is up
to each share driver to support at least one network segmentation type.
#. Network plug-in for using the OpenStack Networking service. It allows to use
any network segmentation that the Networking service supports. It is up to
each share driver to support at least one network segmentation type.
a) ``manila.network.neutron.neutron_network_plugin.NeutronNetworkPlugin``.
This is the default network plugin. It requires that ``neutron_net_id``
and ``neutron_subnet_id`` are provided when defining the share network
that will be used for the creation of share servers. The user may
define any number of share networks corresponding to the various
physical network segments in a tenant environment.

b) ``manila.network.neutron.neutron_network_plugin.NeutronSingleNetworkPlug

for ``neutron_net_id`` and ``neutron_subnet_id`` from the Manila
configuration file and uses one network for all shares.

case. It accepts values for ``neutron_net_id`` and ``neutron_subnet_id``
from the ``manila.conf`` configuration file and uses one network for all
shares.
When only a single network is needed, the NeutronSingleNetworkPlugin (1.b)
is a simple solution. Otherwise NeutronNetworkPlugin (1.a) should be chosen.

serves the networking needs when ``Nova networking`` is configured in
the cloud instead of Neutron. It requires a single parameter,
``nova_net_id``.
b) ``manila.network.nova_network_plugin.NovaSingleNetworkPlugin``. This one
works in the same way as the previous one with one difference. It takes
nova_net_id from the Shared File Systems service configuration file and
creates share servers using only one network.
b) ``manila.network.nova_network_plugin.NovaSingleNetworkPlugin``. This
plug-in works the same way as
``manila.network.nova_network_plugin.NovaNetworkPlugin``, except it takes
``nova_net_id`` from the Shared File Systems service configuration
file and creates the share servers using only one network.

created independently by any other means. The plugin supports any type of
network - flat and segmented. As above, it is completely up to the driver

Networking
==========
Instead of OpenStack Block Storage service, Shared File Systems service
requires interaction with Networking service. The first of all, it because
share services should have a possibility to manage share servers on its own.
Also, lots of shared file systems provides have own access control systems and
requires network connectivity with some external auth providers, like LDAP,
Kerberos, or Microsoft Active Directory. So, management share services base
on such back end needs some interacting with Networking service.
Unlike the OpenStack Block Storage service, the Shared File Systems service
requires interaction with the Networking service. First of all, it is because
the share services require the option to self-manage share servers. Also, for
authentication and authorization of the clients, the Shared File Systems
service can be optionally configured to work with different network
authentication services, like LDAP, Kerberos protocols, or Microsoft Active
Directory.

restore data by running the `manila snapshot-create` command.
To export a snapshot, you can create shares from it, then mount new share to
instance and then directly copy files from attached share into archive.
To import snapshot, create a new share with appropriate size, attach it to
To import a snapshot, create a new share with appropriate size, attach it to
instance and then copy file from archive to attached file system.
