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

2.3: 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

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
