Partitioning of Linux disks

The composition of the disk:

Tracks: Track

Sectors: Sector (512 bytes)

Head: Head

Cylinder: Cylinder

Mbr/msdos partition mode

1--4 primary partition, or 0--3 primary partition plus an extended partition (n logical partitions)

Maximum supported disks with a capacity of 2.2TB.

The extended partition cannot be formatted.

First, see which disks are currently available

ls/dev/sd*

Lsblk

Ii. Division of partitions

View Partition table: FDISK/DEV/SDA

Common Interactive directives:

M: List specified help

P: View the existing partition table

N: New Partition

D: Delete partition

Q: Discard Changes and exit

W: Save Changes and exit

Third, the format of

MKFS Tools

MKFS.EXT3 Partition Device Path

MKFS.EXT4 Partition Device Path

MKFS.XFS Partition Device Path

MKFS.VFAT-F 32 Partition Device path

Example MKFS.EXT3/DEV/SDA1

Mkfs.ext4/dev/sda2

Mkfs.xfs/dev/sda3

Iv. Mounting and use

Example Mkdir/part1

Mout/dev/sda1/part1

V. Viewing mount Usage

Df-h (detects that there are currently no mounted devices to mount)

Refresh Partition Table Partprob

Boot Auto Mount Vim/etc/fstab

Format: Device path mount point type parameter backup mark detection order

Example/dev/sda1/part1 ext3 defaults 0 0

(You can also replace the device path with the UUID, Blkid view the partition UUID file system)

MOUNT-A (detect/etc/fstab boot automatically mount configuration file, format is correct)

Steps:

1. LSBLK View Hard Drive information

2. Fdisk partitioning

3. Partprob refresh, new partition table

4. MKFS.XFS formatted partition

5. Mount Mount Test

6. Vim/etc/fstab Boot automatically mount
