This article mainly introduces how to use the parted command in Linux. It is very detailed and has a certain reference value. Friends who are interested must finish it!

Linux common commands parted command is a powerful disk partition and partition resizing tool developed by the GNU organization. Unlike fdisk, it supports resizing partitions.

Parted disk Partition and Partition Sizing tool

As a tool designed for Linux, it is not built to handle multiple partition types associated with fdisk, but it can handle the most common partition formats, including: ext2, ext3, fat16, fat32, NTFS, ReiserFS, JFS, XFS, UFS, HFS, and Linux swap partitions.

Syntax parted (options) (parameters) option-h: displays help information;-I: interactive mode;-s: script mode without prompting the user;-v: displays the version number. Parameter device: specify the device file corresponding to the hard disk to be partitioned

Command: the parted command to execute.

Since the emergence of serial technology, more and more users have chosen to use large-capacity SATA hard drives to create disk arrays; in particular, MD1000/MD3000 can easily break through 2T LUN, so I will give you some guidance here.

Red Hat Enterprise Linux 4 Update 4 provides support for disk devices greater than 2 terabytes (TB).

Please refer to the following procedure:

Note:

Green represents the commands you need to use.

Red represents the output information you need to pay attention to, which you need to use later.
