NexentaStor5 Driver¶

Nexentastor5 can be used as a storage back end for the OpenStack Shared File System service. Shares in the Shared File System service are mapped 1:1 to Nexentastor5 filesystems. Access is provided via NFS protocol and IP-based authentication.

Network approach¶

L3 connectivity between the storage back end and the host running the Shared File Systems share service should exist.

Supported shared filesystems and operations¶

The drivers supports NFS shares.

The following operations are supported:

Create NFS share
Delete share
Extend share
Shrink share
Allow share access

Note the following limitation:
- Only IP based access is supported (ro/rw).
Deny share access
Create snapshot
Revert to snapshot
Delete snapshot
Create share from snapshot
Manage share
Unmanage share

Requirements¶

NexentaStor 5.x Appliance pre-provisioned and licensed
Pool and parent filesystem configured (this filesystem will contain all manila shares)

Restrictions¶

Only IP share access control is allowed for NFS shares.

Configuration¶

enabled_share_backends = NexentaStor5

Create the new back end configuration section, in this case named 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
