How can I expand the root directory in Linux?

There are mainly two methods to extend the root directory (/) in Linux.

1. Utilize Logical Volume Manager (LVM):
2. Firstly, use the lvextend command to increase the size of the logical volume (LV).
3. Next, use the “resize2fs” command to adjust the file system size to fit the new logical volume size.
4. Using GParted (a graphical partition editor):
5. Firstly, use the GParted graphical tool to adjust the size of the partition where the root directory is located.
6. Next, use the resize2fs command to adjust the file system size to fit the new partition size.

Regardless of the method chosen, it is important to make a backup before performing any action, and ensure an understanding of the impact on data and systems. Additionally, it is recommended to seek guidance from professionals or reference relevant documentation to ensure the accuracy and safety of the operation.
