NFS is a good shared storage system, but performance is not as good under high load conditions.
This is a long time ago to write something, there is nothing wrong hope everyone correct:)

On NFS server:

The nfs server needs to operate and establish on both sides of the CLIENT river SERVER. The specific content is summarized in the article. Some operation steps and command code in this article have been parsed and hope to be useful to you.

NFS server security has always been a hot topic. As the network continues to change, security issues are becoming more and more important. So where can we talk about the security of NFS servers? First, let's take a look at the basic definition of NFS. NFS is short for Network File System. It is an integral part of a di

In the application development stage, the NFS method is more efficient than the ftp method, because it does not need to download the linux server program to the Embedded Target System for debugging. Next we will

NFS, which utilizes Linux operating systems, provides disk space for UNIX, uses the Rman tools of the database to perform a backup of the database, and the backup data is stored in the disk space on the backup server.

NFS is short for Network File System, that is, Network File System. The Network File System is one of the file systems supported by FreeBSD, also known as NFS. NFS allows a system to share directories and files with others on the network. By using NFS, users and programs can access files on the remote system just like
NFS is a good shared storage system, and its performance is poor under high load conditions. The only drawback is that it does not support Windows well.

When constructing the NFS service, we know that creating an NFS server requires a client and a server, and then the two can be connected for communication. Here we will take a look at the client and server settings, and then explain the optimization.
