Tegile Driver
|
|
=============
|
|
|
|
The Tegile Manila driver uses Tegile IntelliFlash Arrays to provide shared
|
|
filesystems to OpenStack.
|
|
|
|
The Tegile Driver interfaces with a Tegile Array via the REST API.
|
|
|
|
Requirements
|
|
------------
|
|
|
|
- Tegile IntelliFlash version 3.5.1
|
|
- For using CIFS, Active Directory must be configured in the Tegile Array.
|
|
|
|
Supported Operations
|
|
--------------------
|
|
|
|
The following operations are supported on a Tegile Array:
|
|
|
|
* Create CIFS/NFS Share
|
|
* Delete CIFS/NFS Share
|
|
* Allow CIFS/NFS Share access
|
|
* Only IP access type is supported for NFS
|
|
* USER access type is supported for NFS and CIFS
|
|
* RW and RO access supported
|
|
* Deny CIFS/NFS Share access
|
|
* IP access type is supported for NFS
|
|
* USER access type is supported for NFS and CIFS
|
|
* Create snapshot
|
|
* Delete snapshot
|
|
* Extend share
|
|
* Shrink share
|
|
* Create share from snapshot
|
|
|
|
Backend Configuration
|
|
---------------------
|
|
|
|
The following parameters need to be configured in the [DEFAULT]
|
|
section of */etc/manila/manila.conf*:
|
|
|
|
+-----------------------------------------------------------------------------------------------------------------------------------+
|
|
| [DEFAULT] |
|
|
+============================+======================================================================================================+
|
|
| **Option** | **Description** |
|
|
+----------------------------+-----------+------------------------------------------------------------------------------------------+
|
|
| enabled_share_backends | Name of the section on manila.conf used to specify a backend. |
|
|
| | E.g. *enabled_share_backends = tegileNAS* |
|
|
+----------------------------+------------------------------------------------------------------------------------------------------+
|
|
| enabled_share_protocols | Specify a list of protocols to be allowed for share creation. For Tegile driver this can be: |
|
|
| | *NFS* or *CIFS* or *NFS, CIFS*. |
|

|
|
| share_backend_name | A name for the backend. |
|
|
+-------------------------------+-----------------------------------------------------------------------------------------------------+
|
|
| share_driver | Python module path. For Tegile driver this must be: |
|
|
| | *manila.share.drivers.tegile.tegile.TegileShareDriver*. |
|
|
+-------------------------------+-----------------------------------------------------------------------------------------------------+
|
|
| driver_handles_share_servers| DHSS, Driver working mode. For Tegile driver **this must be**: |
|
|
| | *False*. |
|
|
+-------------------------------+-----------------------------------------------------------------------------------------------------+
|
|
| tegile_nas_server | Tegile array IP to connect from the Manila node. |
|
|
+-------------------------------+-----------------------------------------------------------------------------------------------------+
|
|
| tegile_nas_login | This field is used to provide username credential to Tegile array. |
|
|
+-------------------------------+-----------------------------------------------------------------------------------------------------+
|
|
| tegile_nas_password | This field is used to provide password credential to Tegile array. |
|
|
+-------------------------------+-----------------------------------------------------------------------------------------------------+
|
|
| tegile_default_project | This field can be used to specify the default project in Tegile array where shares are created. |
|
|
| | This field is optional. |
|
|
+-------------------------------+-----------------------------------------------------------------------------------------------------+
|
|
|
|
Below is an example of a valid configuration of Tegile driver:
|
|
|
|
| ``[DEFAULT]``
|
|
| ``enabled_share_backends = tegileNAS``
|
|
| ``enabled_share_protocols = NFS,CIFS``
|
|
|
|
| ``[tegileNAS]``
|
|
| ``driver_handles_share_servers = False``
|
|
| ``share_backend_name = tegileNAS``
|
|
| ``share_driver = manila.share.drivers.tegile.tegile.TegileShareDriver``
|
|
| ``tegile_nas_server = 10.12.14.16``
|
|
| ``tegile_nas_login = admin``
|
|
| ``tegile_nas_password = password``
|
|
| ``tegile_default_project = financeshares``
|
|
|
|
Restart of :term:`manila-share` service is needed for the configuration changes
|
|
to take effect.
|
|
|
|
