Linux manually mount the hard drive and add it to the file

Common commands for Linux shells

Set command aliases

Alias ' La=ls-al '

In command-line mode

CTRL+ALT+F1---> Ctrl+alt+f6 can control the opening of multiple shells

Shutdown or restart

Restart: Reboot/init 6 shutdown: showdown-h now/init 0

To mount the hard drive:

Virtual Machine---> virtual machines Settings--add to hard drive---> default next you can modify the size

Hard Drive Mount:

Mount Mount

Umount Uninstall

After adding a new hard drive, you will find a new hard disk with no partition (perhaps the name is not the same as mine) through Fdisk-l view/dev/sdb

(1) Partitioning

Fdisk/dev/sdb

Will enter the partition interface

command  (M FOR HELP):  here Press  m  and it will output help;a toggle a bootable  flagb edit bsd disklabelc toggle the dos compatibility flagd  delete a partition  Note: This is the action of deleting a partition;l list known partition types  Note: l   is a list of partition types that allow us to set the type of the corresponding partition;m print this menu  note:m  is a list of help information; n add a new  partition  Note: Add a partition; O create a new empty dos partition tablep  print the partition table  note:p  list partition table;q quit without saving  changes  Note: do not save exit; S create a new empty sun disklabelt change a  partition ' s system id  note:t  change the partition type;u change display/entry unitsv  verify the partition tablew write table to disk and exit  Note: Write the partition table to the hard disk and exit; x extra functionality  (experts only) 

Here we just need n to add partition and W write partition to be able to the other can do without understanding I don't know. 0.0

After selecting N:

Command (M for help): Ncommand action E Extended NOTE: Expanded partition P primary partition (1-4) Note: Primary partition, I Choose this one.

After selecting P

Partition numbers (1-4): Note: Number of partitions created

I can't post the shell on the back of the partition number.

I choose 1 and then it will let you choose from that position to start with that position end of me a partition must be starting from 1 to the end of a number (it will give a 1-xxx) and then choose W to write the hard drive to the hard disk partition is completed

(2) formatting

You can use fdisk-l again to see the one you'll see behind the new hard drive

There is a partition/dev/sdb1 (mine is this 0.0)

The origin of MKFS.EXT3/DEV/SDB1 #/dev/sdb1 begins to format

MKFS can be followed by a number of formatting methods here, I chose ext3 with the others. I don't know, either. 0.0

(3) mounting the hard drive

After formatting, you can mount the hard drive.

Mount-t ext3-o rw/dev/sdb1/newfile #挂载硬盘 #-t and disk format can be omitted the system will automatically detect the #-o and Mount mode RW readable writable #/newfile This is the hard disk partition mount directory, you can follow the Meaning transformation, if there is no need to recreate a folder, I am here myself in the root directory/under the creation of a newfile/folder mkdir NewFile

Press ENTER without responding stating that the mount was successful. ^__^

First list device: Disk device file or label or UUID for the device

1) View the label and UUID of the partition

Label is the label of the partition, in the initial installation of the system is filled with the mount point is the name of the label. You can find the UUID and label name by looking at the information in the superblock of a partition

eg

[[email protected] home]# dumpe2fs-h/dev/sdb1 #查看 virtual machine New second hard drive/dev/sdb1 dumpe2fs 1.41.12 (17-may-2010)         Filesystem volume name: <none> #Label name because it's new so there's no last mounted on: <not available> Filesystem uuid:a792a943-49f7-4e45-b93a-1ddaf2ec8007 #UUID can be added to a file using the UUID

You can also do this by:

[Email protected] home]# blkid/dev/sda1:uuid= "769618DF-6FF5-4CC6-9443-BF112E4E25CF" type= "Ext4"/dev/sda2:uuid= " 7b65d993-2c6d-4410-a98e-1c7d6292d5a7 "type=" Ext4 "/dev/sda3:uuid=" b5c53884-ba55-452c-984d-c9321e3df521 "TYPE=" Swap "/dev/sdb1:uuid=" a792a943-49f7-4e45-b93a-1ddaf2ec8007 "type=" ext3 "//New HDD

Second column: mount point: Device mount points---mounted to that directory

Third column: filesystem: Format of the disk file system, including Ext2, Ext3,ReiserFS, NFS, VFAT, etc.

Fourth column: Parameters: File System parameters

Async/sync	Set whether to run synchronously, default to Async
Auto/noauto	Whether the file system is actively mounted when the MOUNT-A command is downloaded. Default is Auto
Rw/ro	Whether to mount in read-only or read-write mode
Exec/noexec	Restricting the ability to perform operations within this file system
User/nouser	Whether the user is allowed to mount using the Mount command
Suid/nosuid	Whether to allow the existence of suid
Usrquota	Boot file system supports disk quota mode
Grpquota	Boot file system support for group disk quota mode
Defaults	Colleagues have settings for default parameters such as Rw,suid,dev,exec,auto,nouser,async

Fifth column: Can the dump backup command function: Dump is a command used as a backup. Usually the value of this parameter is 0 or 1

0	Rep don't do dump backup
1	Represents a daily dump operation
2	Perform a dump operation that represents an indefinite date

Column sixth: Whether the sector is inspected: During the boot process, the system defaults to fsck to verify that our system is complete (clean).

0	Do not test
1	First Test (Common root directory selection)
2	Inspection after completion of the 1 level inspection

Refer to File Fstab append the newly created hard disk to the file according to the parameters.
