What is the method for expanding the disk in a Linux production environment?

In a Linux production environment, there are several main methods for expanding hard drive capacity:

1. Utilizing LVM (Logical Volume Manager): LVM is an advanced disk partition management tool that allows multiple physical disks or partitions to be combined into a logical volume, enabling disk expansion by extending the logical volume. Specific steps include creating physical volumes, creating volume groups, creating logical volumes, extending logical volumes, and configuring file systems.
2. Using GParted: GParted is a graphical tool that can be used for resizing partitions. You can utilize GParted in Linux to resize partitions and expand the hard drive. The specific steps include launching GParted, selecting the partition to adjust, resizing the partition, applying the changes, and restarting the system.
3. Using fdisk and parted commands: Fdisk and parted are commonly used partition management tools in Linux, allowing for the creation, deletion, and adjustment of partitions. By creating new partitions or adjusting the size of existing ones, it is possible to expand the disk capacity. The specific steps include using fdisk or parted to view the current partition status, create new partitions or adjust the size of existing ones, save the changes, and restart the system.

It is important to note that before expanding the hard drive, be sure to back up important data to prevent data loss. Additionally, different Linux distributions may have different tools and commands, so the specific steps may vary. Please operate according to the actual situation.
