NexentaStor5 Driver for OpenStack Manila

The NexentaStor5 Manila driver provides NFS shared file systems to OpenStack.

Requirements

• The NexentaStor 5.1 or newer

Supported shared filesystems and operations

This driver supports NFS shares.

The following operations are supported:

• Create NFS Share

• Delete NFS Share

• Allow NFS Share access

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

• Deny NFS Share access

• Manage a share.

• Unmanage a share.

• Extend a share.

• Shrink a share.

• Create snapshot

• Revert to snapshot

• Delete snapshot

• Create share from snapshot

Backend Configuration

The following parameters need to be configured in the manila configuration file for the NexentaStor5 driver:

• share_backend_name = <backend name to enable>

• share_driver = manila.share.drivers.nexenta.ns5.nexenta_nas.NexentaNasDriver

• driver_handles_share_servers = False

• nexenta_nas_host = <Data address to NAS shares>

• nexenta_user = <username for management operations>

• nexenta_password = <password for management operations>

• nexenta_pool = <Pool name where NAS shares are created>

• nexenta_rest_addresses = <Management address for Rest API access>

• nexenta_folder = <Parent filesystem where all Manila shares are kept>

• nexenta_nfs = True

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 NexentaStor driver, this extra-spec’s value must be set to False.

Restrictions

• Only IP share access control is allowed for NFS shares.
