Delete an NFS Export
If you delete an NFS export, the data in the shared directory is no longer shared but it is not removed.
Steps
1. Click the Storage view and select a FluidFS cluster.
2. Click the File System tab.
3. In the File System tab navigation pane, select NFS Exports.
4. In the right pane, select an NFS export and click Delete. The Delete dialog box appears.
5. Click OK.
View or Select the Latest NFS Version Supported
NFS v4 is enabled or disabled on a systemwide basis. By default, NFS v4 is disabled, which forces clients to use NFS v3 and earlier. You
might want to use earlier versions if you have clients that are incompatible with NFSv4.
Steps
1. Click the Storage view and select a FluidFS cluster.
2. Click the File System tab, and select Client Accessibility.
3. In the right pane, click the Protocols tab, and then click Edit Settings. The Edit NFS Protocol Settings dialog box appears.
4. For the Maximum NFS Protocol Supported field, click the down-arrow and select the version of NFS that you want to use. The
options are NFSv3, NFSv4.0, and NFS v4.1.
5. Click OK.
Setting Permissions for an NFS Export
To assign users access to an NFS export, you must log in to the NFS export using a trusted client machine account and set access
permissions and ownership of the NFS export using the chmod and chown commands on the NFS mount point.
Accessing an NFS Export
Clients use the mount command to connect to NFS exports on UNIX or Linux systems.
NOTE:
The parameters shown in the command lines are recommended parameters. See the mount command manual
page in the respective operating system for more information and other options.
Global Namespace
Global namespace is a virtual view of shared folders in an organization. This feature allows the Administrator to provide a single point of
access for data that is hosted on two or more separate servers.
Global namespace is enabled by default, and can be configured using the CLI. See the white paper Dell FluidFS FS8600 Appliance CLI
Reference Guide for more information about global namespace commands.
Global Namespace Limitations
• Global namespace is supported on SMB2.x, SMB3.x, and NFSv4.x clients only.
• Global namespace cannot be configured on these volumes:
• NAS volume that reached full capacity
• Replication destination NAS volume (or by any other read-only NAS volume)
• NFSv4 redirection targets support NFSv4 protocol (the remote NAS server supports NFSv4, enabling NFSv4 redirections).
• SMB shares cannot be defined on the redirection folder directly. An SMB share is defined on a local folder that contains the redirection
folder. The redirection folder cannot be defined on SMB shared folder (even when empty).
• Redirection folders cannot be set on non-empty directories.
• NAS virtual volume backup, restore, replication, and snapshot operations are not supported on the remote target data. It is supported
only on the redirection folders (including the redirection data information) that reside inside the local volume data.
• After the NFSv4 or SMB client is redirected to the remote server and establishes the remote connection, the client continues further
communication with the remote server.
