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.

  • IP access type is supported only for NFS.
  • Only FLAT network is supported.
