NFS v4 Implementation
Before implementing NFSv4, note the following, and refer to the respective documentation for your NFSv4 clients:
• User and Group identification — NFSv4 users and groups are identified by a <name>@<domain> string (rather than the traditional
UID/GID numbers). The NFSv4 server (FluidFS) and clients must be configured to use the same external Network Information Service
(NIS) or LDAP domain, which ensures consistent <UID/GID>-<name> mapping of identities. If the string does not map to a domain
object, it defaults to the nobody identity.
• Protection mode— Configure the NAS volume with UNIX security style to allow NFSv4 ACLs. NFSv4 ACLs are supported, but
POSIX ACLs are not.
• Interoperability —
• You can modify permissions or ownership to NFSv4 ACL on UNIX volumes. NFSv4 clients can transparently access UNIX/POSIX
or NTFS protected files. The accessing identity is translated and checked against the UNIX/POSIX or NTFS ACL metadata
(permissions and ownership), to verify access authorization.
• NFSv4 ACL-protected objects can analogously be accessed by NFSv3 and SMB clients.
• Single port configuration — NFSv4 communicates over TCP port 2049 only.
For detailed information about the Network File System (NFS) version 4 protocol, see RFC 7530.
Configuring NFS Exports
View, add, modify, and delete NFS exports, and control the maximum NFS protocol level that the cluster will support.
View All NFS Exports on a FluidFS Cluster
View all current NFS exports for a FluidFS cluster.
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. The NFS exports are displayed in the right pane.
View NFS Exports on a NAS Volume
To view the current NFS exports for a NAS volume:
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, expand NAS Volumes and select a NAS volume.
4. Click the NFS Exports tab. The NFS exports are displayed.
Add an NFS Export
Create an NFS export to share a directory in a NAS volume using the NFS protocol. When an NFS export is added, default values are
applied for some settings. To change the defaults, you must modify the NFS export.
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. Click Create NFS export. The Create NFS export dialog box appears.
5. Select a NAS volume on which to create an NFS export and click OK. The Create NFS export dialog box appears.
6. In the Folder Path field, specify the directory that you want to share:
NOTE:
A folder name must be less than 100 characters long and cannot contain the following characters: >, ", \, |, ?,
and *.
• To share the root of the NAS volume, leave the Folder Path field set to the default value of /.
• To use an existing directory to share, type the path to the directory in the Folder Path field.
