Hitachi NAS Platform File Services Driver for OpenStack
|
|
========================================================
|
|
|
|
Overview
|
|
========
|
|
The Hitachi NAS Platform File Services Driver for OpenStack
|
|
provides NFS Shared File Systems to OpenStack.
|
|
|
|
|
|
Requirements
|
|
------------
|
|
- Hitachi NAS Platform Models 3080, 3090, 4040, 4060, 4080, and 4100.
|
|
|
|
- HNAS/SMU software version is 12.2 or higher.
|
|
|
|
- HNAS configuration and management utilities to create a storage pool (span)
|
|
and an EVS.
|
|
|
|
- GUI (SMU).
|
|
|
|
- SSC CLI.
|
|
|
|
|
|
Supported shared file systems and operations
|
|
--------------------------------------------
|
|
The driver supports CIFS and NFS shares.
|
|
|
|
The following operations are supported:
|
|
|
|
- Create a share.
|
|
|
|
- Delete a share.
|
|
|
|
- Allow share access.
|
|
|
|
- Deny share access.
|
|
|
|
- Create a snapshot.
|
|
|
|
- Delete a snapshot.
|
|
|
|
- Create a share from a snapshot.
|
|
|
|
- Extend a share.
|
|
|
|
- Shrink a share.
|
|
|
|
- Manage a share.
|
|
|
|
- Unmanage a share.
|
|
|
|
|
|
Preparation and Deployment
|
|
==========================
|
|
|
|
.. note::
|
|
|
|
The manila-share node only requires the HNAS EVS data interface if you
|
|
plan to use share migration.
|
|
|
|
.. important ::
|
|
|
|
It is mandatory that HNAS management interface is reachable from the
|
|
Shared File System node through the admin network, while the selected
|
|
EVS data interface is reachable from OpenStack Cloud, such as through
|
|
Neutron flat networking.
|
|
|
|
|
|
Configuration on Kolla deployment
|
|
---------------------------------
|
|
|
|
Enable Shared File Systems service and HNAS driver in
|
|
``/etc/kolla/globals.yml``
|
|
|
|
.. code-block:: console
|
|
|
|
enable_manila: "yes"
|
|
enable_manila_backend_hnas: "yes"
|
|
|
|
Configure the OpenStack networking so it can reach HNAS Management
|
|
interface and HNAS EVS Data interface.
|
|
|
|
To configure two physical networks, physnet1 and physnet2, with
|
|
ports eth1 and eth2 associated respectively:
|
|
|
|
In ``/etc/kolla/globals.yml`` set:
|
|
|
|
.. code-block:: console
|
|
|
|
neutron_bridge_name: "br-ex,br-ex2"
|
|
neutron_external_interface: "eth1,eth2"
|
|
|
|
.. note::
|
|
|
|
eth1: Neutron external interface.
|
|
eth2: HNAS EVS data interface.
|
|
|
|
|
|
HNAS back end configuration
|
|
---------------------------
|
|
|
|
In ``/etc/kolla/globals.yml`` uncomment and set:
|
|
|
|
.. code-block:: console
|
|
|
|
hnas_ip: "172.24.44.15"
|
|
hnas_user: "supervisor"
|
|
hnas_password: "supervisor"
|
|
hnas_evs_id: "1"
|
|
hnas_evs_ip: "10.0.1.20"
|
|
hnas_file_system_name: "FS-Manila"
|
|
|
|
|
|
Configuration on HNAS
|
|
---------------------
|
|
|
|
Create the data HNAS network in Kolla OpenStack:
|
|
|
|
List the available tenants:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack project list
|
|
|
|
Create a network to the given tenant (service), providing the tenant ID,
|
|
a name for the network, the name of the physical network over which the
|
|
virtual network is implemented, and the type of the physical mechanism by
|
|
which the virtual network is implemented:
|
|
|
|
.. code-block:: console
|
|
|
|
$ neutron net-create --tenant-id <SERVICE_ID> hnas_network \
|
|
--provider:physical_network=physnet2 --provider:network_type=flat
|
|
|
|
*Optional* - List available networks:
|
|
|
|
.. code-block:: console
|
|
|
|
$ neutron net-list
|
|
|
|
Create a subnet to the same tenant (service), the gateway IP of this subnet,
|
|
a name for the subnet, the network ID created before, and the CIDR of
|
|
subnet:
|
|
|
|
.. code-block:: console
|
|
|
|
$ neutron subnet-create --tenant-id <SERVICE_ID> --gateway <GATEWAY> \
|
|
--name hnas_subnet <NETWORK_ID> <SUBNET_CIDR>
|
|
|
|
*Optional* - List available subnets:
|
|
|
|
.. code-block:: console
|
|
|
|
$ neutron subnet-list
|
|
|
|
Add the subnet interface to a router, providing the router ID and subnet
|
|
ID created before:
|
|
|
|
.. code-block:: console
|
|
|
|
$ neutron router-interface-add <ROUTER_ID> <SUBNET_ID>
|
|
|
|
Create a file system on HNAS. See the `Hitachi HNAS reference <http://www.hds.com/assets/pdf/hus-file-module-file-services-administration-guide.pdf>`_.
|
|
|
|
.. important ::
|
|
|
|
Make sure that the filesystem is not created as a replication target.
|
|
Refer official HNAS administration guide.
|
|
|
|
Prepare the HNAS EVS network.
|
|
|
|
Create a route in HNAS to the tenant network:
|
|
|
|
.. code-block:: console
|
|
|
|
$ console-context --evs <EVS_ID_IN_USE> route-net-add --gateway <FLAT_NETWORK_GATEWAY> \
|
|
<TENANT_PRIVATE_NETWORK>
|
|
|
|
.. important ::
|
|
|
|
Make sure multi-tenancy is enabled and routes are configured per EVS.
|
|
|
|
.. code-block:: console
|
|
|
|
$ console-context --evs 3 route-net-add --gateway 192.168.1.1 \
|
|
10.0.0.0/24
|
|
|
|
|
|
Create a share
|
|
==============
|
|
|
|
Create a default share type before running manila-share service:
|
|
|
|
.. code-block:: console
|
|
|
|
$ manila type-create default_share_hitachi False
|
|
|
|
+--------------------------------------+-----------------------+------------+------------+--------------------------------------+-------------------------+
|
|
| ID | Name | visibility | is_default | required_extra_specs | optional_extra_specs |
|

|
|
+--------------------------------------+-----------------------+------------+------------+--------------------------------------+-------------------------+
|
|
|
|
Create a NFS share using the HNAS back end:
|
|
|
|
.. code-block:: console
|
|
|
|
manila create NFS 1 \
|
|
--name mysharehnas \
|
|
--description "My Manila share" \
|
|
--share-type default_share_hitachi
|
|
|
|
Verify Operation
|
|
|
|
.. code-block:: console
|
|
|
|
$ manila list

Configure multiple back ends
|
|
============================
|
|
|
|
An administrator can configure an instance of Manila to provision shares from
|
|
one or more back ends. Each back end leverages an instance of a vendor-specific
|
|
implementation of the Manila driver API.
|
|
|
|
The name of the back end is declared as a configuration option
|
|
share_backend_name within a particular configuration stanza that contains the
|
|
related configuration options for that back end.
|
|
|
|
So, in the case of an multiple back ends deployment, it is necessary to change
|
|
the default share backends before deployment.
|
|
|
|
Modify the file ``/etc/kolla/config/manila.conf`` and add the contents:
|
|
|
|
.. code-block:: console
|
|
|
|
[DEFAULT]
|
|
enabled_share_backends = generic,hnas1,hnas2
|
|
|
|
Modify the file ``/etc/kolla/config/manila-share.conf`` and add the contents:
|
|
|
|
.. code-block:: console
|
|
|
|
[generic]
|
|
share_driver = manila.share.drivers.generic.GenericShareDriver
|
|
interface_driver = manila.network.linux.interface.OVSInterfaceDriver
|
|
driver_handles_share_servers = True
|
|
service_instance_password = manila
|
|
service_instance_user = manila
|
|

|
|

|
|

|
[hnas1]
|
|
share_backend_name = HNAS1
|
|

hitachi_hnas_evs_id = <evs_id>
|

|
|
hitachi_hnas_file_system_name = FS-Manila1
|
|
|
|
[hnas2]
|

|
|
driver_handles_share_servers = False
|

hitachi_hnas_ip = <hnas_ip>
|

|
|
hitachi_hnas_password = <password>
