Question: Is NFS Safe?

Why is NFS bad?

The reason is the NFS write cache, which usually does not get flushed until the file is closed.

So when a client removes a file, it will be gone for good, and the file handle is no longer valid— and and attempt to read from or write to that file will result in a “Stale file handle” error..

Is NFS A protocol?

NFS, or Network File System, was designed in 1984 by Sun Microsystems. This distributed file system protocol allows a user on a client computer to access files over a network in the same way they would access a local storage file. Because it is an open standard, anyone can implement the protocol.

What is NFS used for?

The Network File System (NFS) is a client/server application that lets a computer user view and optionally store and update files on a remote computer as though they were on the user’s own computer.
