Infortrend Driver for OpenStack Manila

The Infortrend Manila driver provides NFS and CIFS shared file systems to Openstack.

Requirements

  • The EonStor GS/GSe series Fireware version 139A23

Supported shared filesystems and operations

This driver supports NFS and CIFS shares.

The following operations are supported:

  • Create CIFS/NFS Share

  • Delete CIFS/NFS Share

  • Allow CIFS/NFS Share access

    • Only IP access type is supported for NFS (ro/rw).

    • Only USER access type is supported for CIFS (ro/rw).

  • Deny CIFS/NFS Share access

  • Manage a share.

  • Unmanage a share.

  • Extend a share.

  • Shrink a share.

Backend Configuration

The following parameters need to be configured in the manila configuration file for the Infortrend driver:

  • share_backend_name = <backend name to enable>

  • share_driver = manila.share.drivers.infortrend.driver.InfortrendNASDriver

  • driver_handles_share_servers = False

  • infortrend_nas_ip = <IP address for SSH access to the SAN controller>

  • infortrend_nas_user = <username with the ‘edit’ role>

  • infortrend_nas_password = <password for the user specified in infortrend_nas_user>

  • infortrend_share_pools = <Poolname of the SAN controller>

  • infortrend_share_channels = <Data channel for file service in SAN controller>

Share Types

When creating a share, a share type can be specified to determine where and how the share will be created. If a share type is not specified, the default_share_type set in the manila configuration file is used.

Manila requires that the share type includes the driver_handles_share_servers extra-spec. This ensures that the share will be created on a backend that supports the requested driver_handles_share_servers (share networks) capability. For the Infortrend driver, this must be set to False.

Back-end configuration example

[DEFAULT]
enabled_share_backends = ift-manila
enabled_share_protocols = NFS, CIFS

[ift-manila]
share_backend_name = ift-manila
share_driver = manila.share.drivers.infortrend.driver.InfortrendNASDriver
driver_handles_share_servers = False
infortrend_nas_ip = FAKE_IP
infortrend_nas_user = FAKE_USER
infortrend_nas_password = FAKE_PASS
infortrend_share_pools = pool-1, pool-2
infortrend_share_channels = 0, 1
