tree

It is a regular practice for server administrators. In most cases, large storage devices are divided into separate sections called partitions.

At first, verify that you have available space on the server for partitions.

fdisk -l

Following command will list all detected hard disks:

fdisk -l | grep '^Disk'

Choose disk or device you want to create or make partition (such as /dev/vda, /dev/vda1, /dev/sda, /dev/sdb etc). Here I will partition the disk /dev/sda (256GB) into /dev/sda1 (100GB) and /dev/sda2 (156GB). Please follow the following steps to create partitions accordingly:

Run
```
fdisk /dev/sda
```
Type ‘n’ to create a new partition (/dev/sda1)
Select partition type (default p)
Set partition number (default 1)
Set First sector (default 2048)
Set Last sector of the partition: +100G
Type ‘p’ to view the partition.
Then type ‘n’ to create another partition (/dev/sda2)
Select default partition type, default partition number, default First sector and Last sector
Type ‘p’ to view the partition.
Type ‘w” to save the partition.
Run the command ‘partprobe’ to have the OS detect the new partition table.
```
partprobe
```
Format partitions with the ext4 file system
```
mkfs.ext4 /dev/sda1
mkfs.ext4 /dev/sda2
```
Create a directory to mount the new drive, for example: /data, /backup [Learn more]
- Create directory within root
```
mkdir ~/data
```
- Create directory within /
```
mkdir -p /backup
```
To enable persistent mounting of the file system, even after a reboot, add the following to /etc/fstab:
```
/dev/sda1 /mnt/data ext4 defaults 0 0
/dev/sda2 /mnt/backup ext4 defaults 0 0
```
