What is NFS?

The Network File System, abbreviated as NFS, is a networking protocol that allows for the distributed sharing of files. The process by which data in the form of files is saved to and recovered from storage devices like hard disc drives, solid-state drives, and tape drives is referred to as a “file system,” and it is defined by this process. The Network File System (NFS) is a protocol for exchanging files over computer networks that specifies how data should be saved to and retrieved from various types of storage devices.

The NFS protocol, which was initially created for the purpose of facilitating local file sharing across Unix systems and was made public by Sun Microsystems in 1984, defines a network file system. In 1989, the Internet Engineering Task Force (IETF) was the organization that initially published the specification of the NFS protocol as an internet protocol in the document known as RFC 1094. RFC 7530, also known as the NFS version 4 (NFSv4) Protocol, is the document that contains the NFS protocol’s most recent version’s documentation.

The Network File System (NFS) enables system administrators to share all or a portion of a file system that is on a networked server in order to make it available to computer users who are located at a distance. Mounting NFS shares, which are also referred to as shared file systems, is only possible for clients that have been granted permission to access the shared file system. Requests sent between clients and servers in NFS are forwarded from client to server via Remote Procedure Calls (RPCs).

One of the protocols that are utilized most frequently by file servers is called NFS. There is an implementation of NFS available for the vast majority of contemporary operating systems (OSes), including the following:

Hewlett Packard Enterprise HP-UX

IBM AIX

Windows and Office for Microsoft Linux

Oracle Solaris Cloud suppliers, such as Amazon Elastic File System, NFS file shares in Microsoft Azure, and Google Cloud Filestore, all support the NFS protocol for cloud storage.

Through the use of NFS, users are able to share any device that is capable of being joined to an NFS host file system. This includes things like hard discs, solid-state drives, tape drives, and other peripherals like printers and scanners. Users who are granted the necessary rights are able to access resources on their client machines as if those resources were mounted locally.

Since NFS operates at the application layer, it is not dependent on any particular transport or network protocol stack in order to function. NFS, on the other hand, is typically implemented on computers that are also running the TCP/IP protocol stack. NFS was initially conceived with the purpose of developing a straightforward and stateless protocol for the sharing of remote file systems.

The User Datagram Protocol (UDP) was utilized for the transport layer of early versions of the Network File System (NFS). Because of this, there is no longer a requirement to specify a stateful storage protocol; however, the Network File System (NFS) now supports both the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP). NFS version 3, often known as NFSv3, received support for the Transmission Control Protocol (TCP) a transport layer protocol in the year 1995.

How exactly does one use the Network File System?

The NFS protocol is a client-server format. A host that satisfies the following criteria is considered to be an NFS server.

has the NFS server software installed; has at least one network connection for sharing NFS resources; and is configured to accept and reply to NFS requests across the network connection; all three of these requirements must be met.

1. A host that satisfies the requirements listed below is considered an NFS client.
2. has NFS client software installed; is permitted to access resources on the NFS server; has network connections to an NFS server, and has its configuration set up to send and receive NFS requests via the network connection.
3. NFS was first conceived of as a means of facilitating the sharing of file systems between different workgroups by utilizing Unix. It is frequently utilized even now for the ad hoc sharing of various resources.

The following three steps are included in the process of establishing up NFS service, regardless of whether it is being done on a local workstation or on an enterprise file server:

Check to see if rpc.mounted or just mountd was successfully installed and is operating. This is the NFS daemon, the application that monitors the network for requests related to the NFS file system.

On the server, either create a shared directory or select one to use. This is the mount point for the NFS file system. The NFS resource can be uniquely identified by using the mount point as well as the hostname or address of the server.

It is necessary to configure the permissions on the NFS server in order to grant authorized users the ability to read, write, and run files within the file system.

You can manually configure an NFS client computer to access an NFS server, you can use the mount command, or you can use an NFS configuration file like /etc/exports. All of these options are available to you. Every line in the NFS configuration file has a mount point, an IP address or a host domain name, and any configuration metadata that is necessary to gain access to the file system.

Versions

After client and server machines have successfully negotiated a connection, the following versions of NFS, including the most recent version of NFS, NFSv4, as well as versions released after NFS version 2 (NFSv2), are often compatible with one another.

The following is a list of all NFS versions, starting with the earliest and ending with the most recent:

March of 1984 saw the debut of the Sun Network Filesystem.

In March of 1984, Sun Microsystems was the first company to reveal the first implementation of its network file system. The goal was to allow access to file systems that were both secure and anonymous over the internet. Sun’s goal with the NFS project was to create a file system that was more portable than existing Unix file systems by making it compatible with a variety of operating systems and machine architectures.

NFSv2 was made available in March of 1989.

RFC 1094 contains the specifications for NFSv2. The following was a list of its primary characteristics:

It makes use of the transport protocol known as UDP. Because of this, it is possible to maintain the statelessness of the server while implementing file locking outside of the core protocol.

Due to the fact that its file offsets can only store 32-bit quantities, the maximum size of files that clients can access is 4.2 gigabytes.

It is required that NFS servers commit data written by a client to a disc or non-volatile random-access memory (NVRAM) before replying, and the maximum size of data that may be transferred via this protocol is 8 KB.

NFSv2 is now considered to be deprecated and should not be utilized.

NFSv3 was made available in June of 1995.

The following are some of the additional capabilities and improvements that were included in the RFC 1813-specified NFSv3:

The maximum file size limit of 4.2 gigabytes was eliminated as a result of the extension of file offsets from 32 bits to 64 bits.

It allowed for bigger read and write transfers by relaxing the constraint that limited data transfer to 8 KB and making it optional.

NFS version 3 included support for TCP as an available transport layer protocol option. Read and write transfer capabilities are improved by using TCP transport, which also makes using NFS over a wide area network (WAN) more straightforward.

Added a COMMIT action, which makes it possible to do safe asynchronous writing, as well as an ACCESS RPC, which enhances support for access control lists, also known as ACLs, and power users.

In NFSv3, the server provides a fast response to WRITE RPCs and does not synchronize its state with NVRAM or a disc. The client needs to do nothing more than issue a COMMIT RPC in order to be certain that the data is written to stable storage.

According to recent reports, NFSv3 is still widely used today. It is compatible with NFSv4, although it does not offer support for a significant number of the brand-new and improved capabilities that were introduced with later versions.

NFSv4 was made available in April of 2003.

RFC 3010, which was published in 2000, was the document that initially described the change to NFSv4. Previous versions of the NFS specification were only published by the IETF in an informational capacity, making this the first time that the IETF has presented a version of the specification as a proposed standard.

The following are some of the new and improved features that were incorporated in this update:

support for strong authentication, integrity, and privacy; support for advanced file caching; improved internationalization capability; improved interoperability with Microsoft Windows filesharing; improved support for integrated locking; improved performance and reliability due to communication being handled with compound RPCs and the requirement to use TCP; support for integrated locking; and support for improved internationalization.

There is now a new application programming interface (API) available for any future additions of new security measures.

In 2003, a version of the NFS specification that had been somewhat changed was released as RFC 3530. This was done to correct faults that had been introduced in the initial version and to add some improvements to the protocol.

January 2010 saw the release of NFS version 4.1, also known as NFSv4.1.

NFSv4.1, which was released as RFC 5661, is a minor version protocol that included additional features. These new features include the following:

It made it possible for NFS to be used on global WANs.

In order to resolve concerns relating to bandwidth and scalability, it standardized parallel NFS.

It added support for internationalization by utilizing the UTF-8 encoding standard for file names, directory names, and other identifiers. The ASCII character set has been replaced with UTF-8. It is a character encoding that has a configurable width and is as compact as ASCII, but it is also capable of containing Unicode.

This resulted in the addition of a new session model, which was designed to retain the state of the server in relation to the connections that belonged to the client.

The ability to delegate file operations to the client that was visiting the directory was added via directory delegation.

NFS version 4.2 (NFSv4.2) was made available for download in November of 2016.

NFSv4.2 is documented in RFC 7862. The following are some of the new features and changes that it added:

support for server-side copy, which enables cloning and snapshots of files to be taken by any NFSv4.2 storage server; upgraded modern scale-out storage designs;

space reservations to guarantee that there will be storage space available for a file;

support for sparse files, which are distinguished by the presence of big blocks of zero data that, when read from the file, are sent as zeros;

application data block support, which is what determines the format of a file; support for application data block support

support for tagged NFS, which, when used in conjunction with Security-Enhanced Linux, adds an additional layer of security.

Advantages of Using NFS

The following are some of the many advantages that organizations who use NFS gain:

Mature. Because NFS is an established protocol, the majority of its aspects, including implementing, securing, and using it, as well as its possible flaws, are well understood. This also means that its potential strengths are known.

Open. The Network File System (NFS) is a system that is open, and its ongoing development is described in internet specifications as a protocol that is both open and free.

Cost-effective. NFS is a solution for network file sharing that is both low-cost and easy to set up because it makes use of the infrastructure that is already there in the network.

Managed from a central location The centralized management that NFS provides reduces the amount of additional software and disc space that must be installed on each individual user system.

User-friendly. Users are able to access remote files on remote hosts in the same way that they access local files because the protocol is simple to use and allows for this access.

Distributed. It is possible to use NFS as a distributed file system, which eliminates the requirement for storage devices that can read and write to portable media.

Secure. Because there are fewer removable media in circulation, such as CDs, DVDs, Blu-ray discs, diskettes, and USB drives, the system is more secure thanks to the implementation of NFS.

Disadvantages of NFS

The following is a list of some of the problems that can arise when utilizing NFS:

NFS is inherently unsafe because of its reliance on RPCs, and as a result, it should only be used on trustworthy networks that are protected by firewalls. In such a case, NFS will be susceptible to the dangers posed by the internet.

It has been suggested in studies of NFSv4 and NFSv4.1 that these versions have restricted bandwidth and scalability, and that NFS suffers from performance issues when there is considerable network traffic. It has been claimed that problems with bandwidth and scalability have been resolved with the release of NFSv4.2.
