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.

The following parameters need to be configured in the [backend] section of /etc/manila/manila.conf:

[tegileNAS]

Option

Description

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 manila-share service is needed for the configuration changes to take effect.

Restrictions

The Tegile driver has the following restrictions:

  • IP access type is supported only for NFS.

  • Only FLAT network is supported.
