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
