What is the command to export NFS share?

On the Linux system that runs the NFS server, you export (share) one or more directories by listing them in the /etc/exports file and by running the exportfs command. In addition, you must start the NFS server. On each client system, you use the mount command to mount the directories that your server exported.

What is NFS and how it works?

NFS is an Internet Standard, client/server protocol developed in 1984 by Sun Microsystems to support shared, originally stateless, (file) data access to LAN-attached network storage. As such, NFS enables a client to view, store, and update files on a remote computer as if they were locally stored.

How do I set up NFS?

Install the NFS Client on the Client Systems

1. Step 1: Install the NFS-Common Package. As is the norm, begin by updating the system packages and repositories before anything else.
2. Step 2: Create an NFS Mount Point on Client.
3. Step 3: Mount NFS Share on Client System.
4. Step 4: Testing the NFS Share on Client System.

How do I know if NFS server is exporting?

NFS clients can use the showmount -e command to see a list of exports available from an ONTAP NFS server. This can help users identify the file system they want to mount. Beginning with ONTAP 9.4, ONTAP allows NFS clients to view the export list by default.

What is exports file in Linux?

The /etc/exports file controls which file systems are exported to remote hosts and specifies options. Blank lines are ignored, comments can be made by starting a line with the hash mark (#), and long lines can be wrapped with a backslash (\).

Exporting a directory declares that a directory in the server’s namespace is available to client machines. An NFS client can mount a directory that has been exported by an NFS server. Mounting a directory makes the files that reside on the NFS server available to an NFS client.

What is NFS mounting?

A Network File System (NFS) allows remote hosts to mount file systems over a network and interact with those file systems as though they are mounted locally. This enables system administrators to consolidate resources onto centralized servers on the network.

The exportfs Command. Every file system being exported to remote users via NFS, as well as the access level for those file systems, are listed in the /etc/exports file. When the nfs service starts, the /usr/sbin/exportfs command launches and reads this file, passes control to rpc.

The unwanted people access potential is provided by NFS to access hard drive in a network. So that an unauthorized user can not access one’s email, delete the files.

Which NFS is better?

The failover process is faster for NFS version 3 clients because: The clustering infrastructure now allows one resource per network name instead of one resource per share, which significantly improves resources’ failover time. Failover paths within an NFS server are tuned for better performance.
