Linux adds hard disk partition formatting and mounts

Nux disk partition format and Mount

significance : Add a hard disk to the Linux system server

experimental Environment : VirtualBox virtual software + centos6.5

Step One: Add hardware hard drive ( I use virtualBox simulation here )

Start

View the device and Locate the newly added hard drive ID

Fdisk-l

Partition

Fdisk/dev/sdb

Description :

P-- primary partition [1-4] or view existing partition

N-- add a partition

D-- Delete partition

+1G-- allocate 1G space

W-- Save and exit

Partition Completion View

Fdisk-l

Next format

Mke2fs/dev/sdb1

Mke2fs/dev/sdb2

Mke2fs/dev/sdb3

Mke2fs/dev/sdb4

Description :

Linux file system with ext2, ext3, Ext4

CentOS 7 start file system supports XFS for massive data

format to ext2 file system

MKE2FS Hard Drive device - t specify file system

formatted as EXT3/4

MKE2FS Hard Drive device - t ext3

MKE2FS Hard Drive device - t Ext4

Example :

Mke2fs/dev/sdb1-t ext3

Mke2fs/dev/sdb2-t EXT4

Upgrade or format

Mke2fs-j/DEV/SDB1

Mke2fs-j/DEV/SDB2

Mke2fs-j/DEV/SDB3

Mke2fs-j/DEV/SDB4

detect if there is an error and the error will be fixed automatically

E2fsck-p/DEV/SDB1

To view the detailed properties of a partition

Tune2fs-l/DEV/SDB1

Set the maximum number of mounts

Example : setting up to mount up to three times

Tune2fs-c 30

Can see the maximum number of times to mount and the number of mounts mounted

Tune2fs-l Equipment

set up to mount up to days

Tune2fs-i 30D/DEV/SDB1

View

Tune2fs-l

Modify Partition Name

E2LABEL/DEV/SDB1 New name

Example :

E2LABEL/DEV/SDB1 Mydisk1

Tune2fs-l/DEV/SDB1

Mount : after partition formatting , cannot be used directly , need to mount

The first kind of temporary mount

Mount Device - t file system mount point

To create a mount point

Mkdir-p/MNT/MEDIA/SDB1

Mkdir-p/MNT/MEDIA/SDB2

Mkdir-p/MNT/MEDIA/SDB3

Mkdir-p/MNT/MEDIA/SDB4

Mount

Mount/dev/sdb1/mnt/media/sdb1

Mount/dev/sdb2/mnt/media/sdb2

Mount/dev/sdb3/mnt/media/sdb3

Mount/dev/sdb4/mnt/media/sdb4

The second type : the permanent mount server restarts, automatically takes effect , no need to manually mount

Configure /etc/fstab

Make the Mount effective

Mount-a

View mounts such as partition file system

Mount

Can see hard disk information

Df-h

To use the hard drive after mounting :

Etc/fstab Configuration Instructions

/DEV/SDB1/MNT/MEDIA/SDB1 ext3 defaults 0 0

first item : equipment

Second Item : mount point is a directory

Third Item : file System

Item Fourth : file system Parameters

Item Fifth : whether to back up

Sixth : whether to detect sectors from fsck

Knowledge :

SDA the first hard drive has sda1 under its partition , Sda2

SDB second hard drive has sdb1, SDB2, SDB3, SDB4 under its partition
