Two tips:
*The newly added hard disk needs to restart the server fdisk -l to see
*The following operation uses the root account
, which is probably like this, view-partition-format-mount-restart auto-mount
1. Restart after adding a hard disk Server view
[root@test199 ~]# fdisk -l

2. Partition
fdisk You can use the m command to view the internal commands of the fdisk command;
a: The command specifies the boot partition;
d: The command deletes an existing partition;
l: The command displays a list of partition ID numbers;
m: Check the fdisk command help;
n: command to create a new partition;
p: command to display the partition list;
t: command to modify the type ID number of the partition;
w: command to save the modification of the partition table to make it work.
[root@test199 ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x515ae162.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').
Command (m for help): n
Command action
e extended //Enter e to create an extended partition
p primary partition (1-4) // Enter p to create a logical partition
p
Partition number (1-4): 1 // here Enter l to enter the logical partitioning stage.
First cylinder (1-26108, default 1): //Note: This is the Start value of the partition; it is best to press Enter here . If you enter a non-default number, It will cause a waste of space;
Using default value 1
Last cylinder, +cylinders or +size{K,M,G} (1-26108, default 26108): I just press Enter and use it all. Note: This is to define the size of the partition, +200M means the size is 200M; of course, you can also calculate it according to the size of the unit cylinder indicated by p, and then specify the value of End. Look back and see how it is calculated; it is still more intuitive to use the method of +200M to add. If you want to add a partition with a size of about 10G, please enter +10000M;
Using default value 26108
Command (m for help): w // Finally enter w and press Enter to save .
The partition table has been altered!

[root@test199 ~]# mkfs.ext3 /dev/sdb1 //Note: Format /dev/sdb1 as ext3 type, confirm, my above /dev/sdb1 is new Add 200GB hard disk, just press Enter in this step, it will automatically pop up after formatting

4. Mount
- create a directory first, then mount it to the directory
[root@test199 ~] # mkdir /data
[root@test199 ~]# mount /dev/sdb1 /data
[root@test199 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
