Title: Learn How to Merge Linux Partitions in 10 Minutes
Linux is a popular operating system used by many users around the world. One of the tasks that users might encounter while using Linux is merging partitions. This can be useful if the user wants to increase the storage space or make better use of the avlable disk space.
In this article, we will guide you through how to merge partitions in Linux in just 10 minutes. We will cover different methods that you can use to accomplish this task, depending on your level of experience with the Linux operating system. We will also provide step-by-step instructions to help make the process easier for you.
Method 1: Using the Command Line
If you are comfortable using the command line interface, you can merge partitions using the ‘fdisk’ command. The following steps will guide you through the entire process:
Step 1: Open the Terminal
Open the terminal or command line interface on your Linux machine.
Step 2: Check the Partition Table
Enter the command ‘sudo fdisk -l’ to list all the partitions on your disk. Check the partition table to ensure that you have two or more partitions that you want to merge.
Step 3: Delete the Unwanted Partition
Enter the command ‘sudo fdisk /dev/sdb’ (replace ‘sdb’ with the name of the disk that contns the partition you want to delete). Press ‘d’ on your keyboard to delete the unwanted partition. If you have more than one partition to delete, repeat this process until you have deleted all the unwanted partitions.
Step 4: Resize the Partition
Enter the command ‘sudo fdisk /dev/sdb’ (replace ‘sdb’ with the name of the disk that contns the partition you want to resize). Press ‘n’ on your keyboard to create a new partition, and then press ‘p’ to select ‘Primary’. Enter the start and end sectors for the new partition. You can use the ‘w’ command to write the changes to disk.
Step 5: Format the New Partition
Enter the command ‘sudo mkfs.ext4 /dev/sdb1’ (replace ‘sdb1’ with the name of the new partition). This will format the new partition with the ext4 file system.
Method 2: Using GParted
GParted is a graphical tool that you can use to merge partitions. Here are the steps to follow:
Step 1: Install GParted
Open the Terminal and enter the command ‘sudo apt-get install gparted’ to install GParted on your machine.
Step 2: Launch GParted
Launch GParted from your Applications menu.
Step 3: Choose the Partition
Select the partition that you want to delete by right-clicking on it and choosing ‘delete’. If you have more than one partition to delete, repeat this process until you have deleted all the unwanted partitions.
Step 4: Expand the Partition
Select the partition that you want to expand by right-clicking on it and choosing ‘resize/move’. Drag the slider to expand the partition to the desired size.
Step 5: Apply the Changes
Click on the ‘Apply’ button to apply the changes that you have made to the disk partitions.
Conclusion
Merging partitions in Linux can be achieved through different approaches, depending on your level of experience with the operating system. Using either the command line or GParted tool provides an easy way to merge partitions and utilize the avlable space more effectively. Follow these steps to merge partitions in Linux with ease, and free yourself from storage space concerns.

LINUX安装后如何认第二块硬盘
一、整体流程
1、把新硬盘连接起来
2、在CMOS里陵腔答配置新硬盘
3、查看硬盘代号
4、用 fdisk 对硬盘进行分区
5、格式化分区
6、创建挂载点
7、设置/dev/fstab 以便开机时自动挂载分区
8、设置新硬盘分区的读写权限
二、具体操作步骤
1、把新硬盘连接起来,属于硬件操作，注意主板和硬盘的接口插正确就可以了。
2、在CMOS里配置新硬盘
启动计算机，并进入CMOS，让机器找到新硬盘。
IDE Channel 0Master: none (没有盘)
IDE Channel 0Slave: none (没有盘)
IDE Channel 1Master: 是DVD－ROM
IDE Channel 1Slave: none (没有盘)
IDE Channel 2Master: HDS728080PLA380 (原来的80GBSATA I 硬盘)
IDE Channel 3Master: none (没有盘)
在none 的Channels一个一个地让计算机自动寻找硬盘。最后发现了：
IDE Channel 3Master: STAS (新的1000GB SATA II型硬盘)
3、 查看硬盘代号
$ df
发现：
写道
/dev/sda1 /C_disk 15GB 7 (reserved for Windows XP, my PC is adual- system)
/dev/sda2 / 15GB 83 (Linux)
/dev/sda3 LinuxLVM 8e (Linux)
/dev/sda4 extended
/dev/sda5 82 (Linux Swap, 512MB, twice of the momoey)
/dev/sda6 /data 83 (Linux, mounted on /data, 45.5GB)
注意： SATA (通常称串口盘) 在Linux下被视为SCSI 盘(一种早期用在Sun工作站上和服务器 的高速硬盘，那时很贵！)。
尺慧可以判定： 新的硬盘应该就是/dev/sdb 了。
进入超级用户：
写道
$ su -l
password: yoursecrets
#
# fdisk -l
出现类似下面的信息(以下提示信息仅供参考，有的并非本人实际操作时的屏幕显示，但意思是一样 的)：
写道
Disk/dev/sda: 10.7 GB,bytes
255heads, 63 sectors/track, 1305 cylinders
Units= cylinders of* 512 =bytes

255heads, 63 sectors/track, 261 cylinders
Units= cylinders of* 512 =bytes
Diskidentifier: 0x
Disk /dev/sdb doesn’t contain a validpartition table
4、 用 fdisk 对硬盘进行分区
写道
#fdisk /dev/sdb
Devicecontains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Buildinga new DOS disklabel with disk identifier 0x623223a1.

Command (m for help): w
Thepartition table has been altered!
Callingioctl() to re-read partition table.

5、格式化分区
写道
# mkfs.ext4 -L disk2 /dev/sdb1 －－格式化的同时给新硬盘加标签为 disk2
或者 mkfs.ext4 /dev/sdb1 －－只格式化但不加标签
单独加标签的命令是： # e2label /dev/sdb1 /disk2
6、创建挂载点
写道
# mkdir /disk2
7、设置/dev/fstab 以便开机时自动挂载分区：
写道
# vi /etc/fstab
添加一行：
/dev/sdb1 /disk2 ext4 auto 1 2
若一次性手动挂载分区 ，使用命令： #mount /dev/sdb1 /disk2/
8、设置新硬盘或分区的读写权限：
# chmod a+w /disk2
这样所有计算机的用户都可以读写该分区，即/disk2盘了
不知道你是什么发行版，首先运行终端，在root用户下，或者是用sudo命令查看
# fdisk -l
或者
$ sudo fdisk -l
设备 启动 起点 末尾 块 Id 系统/dev/sdaLinux/dev/sdaLinux swap / Solaris/dev/sdaf W95 Ext’d (LBA)/dev/sda4 *HPFS/凳亩NTFS/exFAT/dev/sdab W95 FAT32/dev/sdaHPFS/NTFS/exFAT终端会列出来你所有的存储设备。
以上是我的存储设型粗备，我只有一个硬盘所以都是/dev/sda
如果是你的应该会有/dev/sdb，/dev/sdc
也可能是别的字母，这里做个例子
假如/dev/sdb是你第二块硬盘，这时候你要把它格式化为linux系统能识别的磁盘格式，更好是EXT4.
继续输入命令
# fdisk /dev/sdb
或者
$ sudo fdisk /dev/sdb
此时会有很多提示，简单的操作就是，接下来按字母o回车。
然后按字母n回车，字母p回车，数字1回车，数字2023回车，直接回车，字母w回车。
然后第二块硬盘就被格式化成linux系统能识别的格式了卜粗镇，第3块同样的操作～
谢谢，望采纳～
一般都会识别的
fdisk -l
看一下，三基茄丛块硬盘应该分搏樱别是/纳斗dev/sda、/dev/sdb、/dev/sdc
MOUNT 详细看下LINUX下这个挂载命令棚桐，会使你进步岩游很多的。
详细的步骤，是不太可能跟你说得清的。你还没有明白挂载相对于LINUX是什么意义的情况下，详细的步骤说了等于链枣坦没说。
知其然不知其所以然。。。非常可怕。。。。
数据无价滴。。
盘都在，设备都在/dev下
