How Do I Check the Disk Mounting Status in Linux?

Run the df -h command to check the mounting status of the disk.

1. Check whether the hard disk can be recognized.

2. Mount the hard disk.

1. Temporarily create a directory in the local hard disk.

2. Mount a partition dev sdb1 to tmp1 in the second hard disk

3. Check whether it is mounted.

3. Unmount the hard drive.

Hard disk is one of the main storage media of a computer, consisting of one or more aluminum or glass discs. The disc is covered with a ferromagnetic material.

Hard disks include solid-state drives (SSD disks, modern hard disks), mechanical hard disks (HDD traditional hard disks), and hybrid hard disks (HHD is a new hard disk born based on traditional mechanical hard disks). SSD uses flash memory particles for storage, HDD uses magnetic disks for storage, and hybrid hard disk (HHD) is a kind of hard disk that integrates magnetic hard disk and flash memory.

The vast majority of hard drives are fixed hard drives that are permanently sealed and fixed in the hard drive.

Basic introduction. Hard disk, known as hard disk in Hong Kong and Taiwan, is one of the main storage media of computers, consisting of one or more aluminum or glass discs. These discs are covered with ferromagnetic material.

The vast majority of hard drives are fixed hard drives that are permanently sealed and fixed in the hard drive.

Head Reset Energy Saving Technology: Energy savings are achieved by resetting the head during idle hours.

Multi-head technology: It is used in servers and database centers to speed up the disk by adding multiple heads to read or write at the same time on the same disk, or to use the head to read or write to the disk at the same time on multiple disks.

In the Windows operating system, mounting usually refers to assigning a drive letter to a disk partition (including a disk partition that has been virtualized). Third-party software, such as disk partition management software, virtual disk software, etc., often also comes with mounting capabilities. In the Linux operating system, mounting is the attachment of a device (usually a storage device) to an existing directory.

To access the files on the storage device, we must mount the partition where the files are located to an existing directory, and then access the storage device by accessing that directory.

Run the df -h command to check the mounting status of the disk.

Additional notes on hard disk mounting:

1. Check whether the hard disk can be recognized.

#fdisk

l Find the information of the new hard disk, similar to the following text:

diskdev/sdb:

gb,36748945408

bytes 2. Mount the hard disk.

1. Temporarily create a directory in the local hard disk.

#mkdir

opt/data/tmp1

2. Mount a partition dev sdb1 to tmp1 in the second hard disk

#mount

dev/sdb1

opt/data/tmp1

3. Check whether it is mounted. #df

Check to see if there is text similar to the following.

dev/sdb1

opt/tmp/tmp1

3. Unmount the hard drive.

#umount

dev/sdb1

df command description.

The df command is used to display the available disk space on a disk partition. The default display unit is KB. You can use this command to get information about how much space the hard drive is occupying and how much space is left.

Grammar. df (option) (parameter).

Options. a or --all: contains all file systems;

block-size="Block size": displays the number of blocks with the specified block size;

h or --human-readable: displays information in a highly readable manner;

h or --si: Same as -h parameter, but calculated with 1000

bytes is a conversion unit, not 1024

bytes；

i or --inodes: displays the information of the inode;

k or --kilobytes: the specified block size is 1024 bytes;

l or --local: displays only the local file system;

m or --megabytes: specifies a block size of 1048576 bytes;

no-sync: Do not execute the sync command before obtaining the disk usage information, this is the default value;

p or --portability: use the output format of posix;

sync: Execute the sync command before obtaining disk usage information.

tFile System Type or --type=File System Type: displays only the disk information of the specified file system type.

t or --print-type: displays the type of the file system;

xFile System Type or --exclude-type=File System Type: Do not display the disk information of the specified file system type;

help: Show help;

version: displays the version information.

Parameter. File: Specifies the file on the file system. Instance.

To view the Linux mounted disk, perform the following steps:

1.The remote host that successfully logged in to Linux.

2.Enter the command df -h to view the current disk, this command will display the mount disk and mount point, there are currently three: logical volume, temporary file, and disk sdb.

3.At this moment, if you think that a disk may not be mounted, you can use the fdisk -l command to check the specific situation of the local disk, and sure enough, the first partition of the disk sda, sda1, is not mounted, which is a boot program.

4.Now, use the mount command mount to mount sda1, for example: mount dev sda1 boot, after the execution, if there is no prompt output, it proves that the execution has been successful, which is a feature of Linux.

5.Finally, run the df -h command again to check the disk usage, which contains the mount point of the disk. This solves the problem of viewing the Linux mount disk.

How Do I View Unmounted Disks in Linux? Let's find out.

1. Open the Linux system.

Right-click on an empty space on the Linux desktop.

2. In the first pull option of the lower positive mold that pops up, click to open the terminal.

3. Use the fdisk l command to check which disks are currently available.

4. Then use the df h command to see which disks have been mounted.

5. Finally, you can compare the two to find out which pure disks are not mounted.

This article is based on the thinkpade15 brand and centos7 system.

cat /proc/mounts

Or just mount

If you only look at the hard disk, you can grep it.

cat /proc/mounts |grep ^/dev/s

Directly on mount you can find the mount status.

df -h can be executed.

Enter the mount command directly.

You can then list the information of all the disks that are currently mounted.

Both local and external.

Just 6 steps! Mounting a hard disk under the Linux system no longer bothers you!

Graphical interface, open the file manager, there is the partition name on the left, click the prompt to enter the password.

This password is either the root user password or the current user password. The specific password depends on the system.

Look at the manual, it's easy to crash.
