Increase or Decrease the size of Static Partition in Linux

Hey, Everyone today we will change the size of the static partition in Linux. So, this will be a step to step guide how can you change the size of the partition and in your Linux system.

Here I will create a partition of a smaller size and then mount it to a folder and then extend it to a larger partition.

Pre-requisite:

1. A system with Linux installed in your system.
2. Space in your drive to which you want to extend the partition.

STEP 1: First we have to check the disk partition of the system

# fdisk -l

As I have a drive of 3 GiB attached to my system I will use it to create a partition of smaller space 1GiB which I will extend further.

STEP 2: Now to create a partition of 1GiB I will use fdisk command to create the partition

# fdisk /dev/<name_of_the_drive>

Then " n " to create a new partition

Then we have to enter the partition number, here the default is 1 so I will go with the default.

Now we have to select the size of the partition and from what sector it should start and at what sector it should end I will choose the default 2048 for the starting of the partition and +1G to create a partition size of 1 GiB.

Lastly, we have to press " w " and hit Enter key to write the changes.

STEP 3: Formatting the partition which will make the inode table for the size of 1GiB

# mkfs.ext4 /dev/<name_of_the_drive>

STEP 4: Create a directory where we will mount the partition

# mkdir <name_of_the_folder>

I have created a folder by name mount_here there I will mount the partition of 1GiB

STEP 5: Mounting the partition to the directory

First, we will run the command

# df -hT

to check all the mounting directories of the drives

We can see that the newly created partition is not mounted anywhere

Now we will mount the partition to the directory

# mount /dev/<drive_name> /<directory_location>

STEP 6: Creating data inside the directory.

STEP 7: Creating a partition of 2GiB

STEP 8: Formatting the newly created partition

# mkfs.ext4 /dev/<drive_name>

STEP 9: Mounting the newly created partition

First, we have to unmount the previous partition

# umount /dev/<partition_name>

# mount /dev/<partition name> /<mounting folder>
