unique file structure. Each partition in Red Hat Linux is part of the entire file system because it uses a processing method called "mount point", which contains a full set of files and directories in the entire file system, and links a partition to a directory. At this point a partition to be loaded will make its storage space available in one directory.Let's start by looking at how Red Hat Linux drives a

Solve the mount timeout problem of the old linux nfs system, nfsmountBackground
Due to business needs, the school needs to transplant the examination system to the cloud platform. The first step is to mount the nfs storage platform of the old system A to the new system B. The old examination system A has been in service for A long time. The operating system is re
drive device in the/dev/directory. However, this device cannot be used before it is mounted, mounting is to use (that is, to open) the USB flash drive device. Where to mount it means that we can open it like opening a file. Of course, it is still different from general files, "property" is "device "! This is the function of mounting the USB flash drive.

This article introduces the basic usage of the Mount/umount command in Linux and automatic mount, the following methods are as follows:
The Mount command format is as follows:
Format: Mount [-parameters] [device name] [Mount Point]
Among the commonly used parameters are:
device that is automatically created to store ININRD. During kernel initialization, the kernel/dev/initrd the contents of the device and copies it to the/DEV/RAM0 device. and mount the/DEV/RAM0 device as the original root file system. If/DEV/RAM0 is specified like this, then/DEV/RAM0 is specified as the real root file system. If you do not specify a real root file system directly by using/DEV/HDA8, then you will use the default RAM0
Before learning Linux, after all, he did not engage in the operation of the dimension, only pay attention to the use of a lot of commands, not too concerned about the file system this piece. Bought a book of Linux, this part of the read something, take a note haha.There is a scene, for example, our current server is not enough storage, then of course we need to add a hard disk, right.When you add a hard disk to a Linux drive, you save data to the hard

1) insert a USB flash drive
2) Input fdisk-l/dev/sda to view the output result. For example, mine is like this:

Disk/dev/sda: 131 MB, 131104768 bytes
3 heads, 32 sectors/track, 2667 cylinders
Units = cylinders of 96*512 = 49152 bytes

Background:The default specified file directory for Hadoop's HDFs file system mount is/mnt/disk{n}. When operators, accidentally attached to the disk in other directories, such as/mnt/data,/mnt/disk01,/mnt/diska, HDFs will select the root partition, when the data is poured into HDFs, the result is often the root partition is quickly consumed, and other partitions are not used.In the CDH version, the configuration of HDFs is as follows:Dfs.datanode.dat
