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

Requirements

• The following service should be enabled on NAS system:
  • CIFS
  • NFS

Supported Operations

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
• Extend a share.
• Shrink a share.

Backend Configuration

The following parameters need to be configured in the [DEFAULT]
section of manila configuration (/etc/manila/manila.conf):

• enabled_share_backends – Name of the
  section on manila.conf used to specify a backend i.e.
  enabled_share_backends = macrosan
• enabled_share_protocols – Specify a
  list of protocols to be allowed for share creation. The VPSA driver
  support the following options: NFS or CIFS or NFS,
  CIFS

The following parameters need to be configured in the [backend]
section of manila configuration (/etc/manila/manila.conf):

• share_backend_name = <backend name
  to enable>
• share_driver =
  manila.share.drivers.macrosan.macrosan_nas.MacrosanNasDriver
• driver_handles_share_servers =
  False
• macrosan_nas_ip = <IP address for
  access to the NAS controller>
• macrosan_nas_port = <Port number
  for access to the NAS controller>
• macrosan_nas_user = <username for
  access>
• macrosan_nas_password = <password
  for the user specified in macrosan_nas_user>
• macrosan_share_pools = <Poolname
  of the NAS 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 Macrosan driver, this must be set to False.

Back-end configuration
example

[DEFAULT]
enabled_share_backends = macrosan
enabled_share_protocols = NFS, CIFS

[macrosan]
share_backend_name = MACROSAN
share_driver = manila.share.drivers.macrosan.macrosan_nas.MacrosanNasDriver
driver_handles_share_servers = False
macrosan_nas_ip = FAKE_IP
macrosan_nas_port = 8443
macrosan_nas_user = FAKE_USER
macrosan_nas_password = FAKE_PASSWORD
macrosan_share_pools = fake_pool1, fake_pool2
