Resize Partition in CentOS 7: Complete Guide

You can resize the partition of CentOS 7 by following these steps:

1. Firstly, you need to use partition tools like fdisk or parted to check the current partition situation. You can run the following command to view the partition status:

sudo fdisk -l

1. Identify the partition you want to resize and then unmount it. You can run the following command to unmount the partition (assuming the partition you want to resize is /dev/sda1):

sudo umount /dev/sda1

1. You can use the resize2fs command to adjust the size of a partition. Suppose you want to expand the /dev/sda1 partition to 10GB, you can run the following command:

sudo resize2fs /dev/sda1 10G

1. To adjust the size of the partitions, you can use either fdisk or parted. You can open the partition tool by running the following command:

sudo fdisk /dev/sda

Next, delete the existing partition and create a larger one. Finally, write the changes to the disk.

1. Finally, remount the partition and verify that the size adjustment has been successful. You can run the following command to remount the partition:

sudo mount /dev/sda1 /mnt

Then, you can run the df -h command again to check the size of the partition.

Please note that resizing partitions is a high-risk operation, and it is recommended to backup important data before proceeding.
