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.
