Resize Partitions in CentOS: Non-destructive Guide

There are two ways to adjust partitions without data loss on CentOS: using the GParted tool or using the command-line tool fdisk.

1. Utilizing the GParted tool:
2. First, install the GParted tool with the command: sudo yum install gparted.
3. Open the GParted tool: sudo gparted
4. Choose the partition you want to adjust, right click and select the “Resize/Move” option, then drag the partition boundary to adjust its size.
5. Click the “Apply” button to implement the changes.
6. Utilize the fdisk command line tool:
7. To begin, open the terminal and run the fdisk command: sudo fdisk /dev/sdX

   Here, /dev/sdX is the device name of the partition you want to adjust.

8. Use the commands to delete the existing partition and create a larger one:
   d (delete existing partition)
   n (create new partition)
   w (save changes)
9. Adjust the file system size using the resize2fs command: sudo resize2fs /dev/sdX

   Where /dev/sdX is the device name of the partition you want to resize.

Please be sure to back up important data before making any partition adjustments to avoid accidental data loss.
