Linux new disk partition format and Mount-fdisk command

This paper mainly solves the problem of disk partition formatting and mount of Linux system.
Attention:
Partitioning operations for disk VDA,SDA, etc.
VDA1,SDA1, etc. is the name of the partition

1. Check the current disk partition status

1.1. View the partition Mount situation

DF -H

2. Partitioning the disk into a formatted operation

2.1. Partitioning the VDB disk

Fdisk/dev/vdb

The following are common partitioning operations:

M print Menu
N New Partition
D Delete Partition
P Print Partition Table
W Write partition Table Save
Q exit

P Select Primary Partition
E Select an extended partition
1 Select a partition number
Select initial position, default is 1
Until the end of the selection, the default is the end of disk

2.2. Re-view the disk partition table

2.3: Reload Disk partition information

Partprobe/dev/vdb1

Using the Fdisk tool simply writes the partition information to the disk,
You need to use Partprobe to let kernel re-read the partition information before formatting the partition value, and if unsuccessful, restart the system
No return is the read success

2.4. Format the partition of the disk

Mkfs.ext4/dev/vdb1

2.5. Format to complete the subsequent optimization of the configuration

Tune2fs-c-1

3. Mount Partitions

3.1. Mount the partition to the specified directory

mkdir -P/dataMount /dev/vdb1/data

3.2. Configure the boot auto-mount partition
