Macrosan Driver for OpenStack Manila

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
