# 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.

## Back-end configuration example

    [DEFAULT]
    enabled_share_backends = NexentaStor5

    [NexentaStor5]
    share_backend_name = NexentaStor5
    driver_handles_share_servers = False
    nexenta_folder = manila
    share_driver = manila.share.drivers.nexenta.ns5.nexenta_nas.NexentaNasDriver
    nexenta_rest_addresses = 10.3.1.1,10.3.1.2
    nexenta_nas_host = 10.3.1.10
    nexenta_rest_port = 8443
    nexenta_pool = pool1
    nexenta_nfs = True
    nexenta_user = admin
    nexenta_password = secret_password
    nexenta_thin_provisioning = True
