How to Manage Storage and Partitions in Debian 11
Managing storage and partitions in debian 11 is the easiest thing ever in debian but if you’re having a difficulty here then you don’t need to feel bad about it. We here will tell you how you can manage storage and partitions in debian 11 easily.
So, let’s get to it by starting with a small introduction.
Introduction
Managing storage and partitions in Debian 11 can be done using various tools such as command-line utilities like fdisk, parted, and gdisk, or graphical tools like GParted.
Here are the general steps you can follow to manage storage and partitions in Debian 11:
-
Check existing partitions
Before creating new partitions, it is important to check the existing partitions on your system. To view a list of all the partitions on your machine, type sudo fdisk -l. This command will show you the device name, partition type, file system type, size, and mount point of each partition.
-
Choose a partitioning tool
There are various partitioning tools available in Debian 11 such as fdisk, parted, and gdisk. Each tool has its advantages and disadvantages. Here’s a brief overview:
fdisk:
A command-line utility that is simple and easy to use. It can be used to create, delete, and modify partitions on a disk.
parted:
A command-line utility that is more advanced than fdisk. It supports more partitioning schemes and file systems and can be used to resize existing partitions.
gdisk:
A command-line utility that is similar to fdisk but is specifically designed for GPT partitioning schemes.
Choose the tool that suits your needs and preferences.
-
Create a partition table
Before creating new partitions, you need to create a partition table on the disk. A partition table is a data structure that defines the layout of the disk, including the number and size of partitions. There are two types of partition tables: MBR and GPT.
/dev/sdX is the name of the device you wish to partition, and partition-type> is the type of partition table you want to create, such as msdos for MBR or oMS-DOS for GPT. To build a partition table, run the command sudo parted /dev/sdX mktable partitmutablee>.
For instance, you can use the following command to construct a GPT partition table on the /dev/sda device:
sudo parted /dev/sda mktable gpt
This command will erase all the data on the disk, so make sure to back up your data before proceeding.
-
Create partitions
Once you have created a partition table, you can create new partitions on the disk. To create a new partition, use the partitioning tool of your choice and follow these steps:
Specify the partition size: Specify the size of the partition in megabytes or gigabytes. You can also use percentages to allocate a portion of the disk to the partition.
Indicate the kind of file system: Choose the ext4, NTFS, or xfs file system type that you want to use for the partition.
Specify the mount point: Choose the mount point where you want the partition to be mounted, such as /home, /var, or /data.
For example, to create a new partition on the /dev/sda device using fdisk, you can use the following steps:
To start fdisk, type sudo fdisk /dev/sda.
In order to create a new partition, press the key n.
Specify the partition size in megabytes or use the default value.
Specify the partition type as primary or extended.
Specify the partition number, such as 1 or 2.
To change the partition type, use the key t.
Enter the file system you want to use as the partition type, such as 83 for Linux or 07 for NTFS.
To save the modifications to the disc and quit fdisk, use the key w.
-
Format partitions
Use the command sudo mkfs.<filesystem-type> /dev/sdXY to format the partition. Replace <filesystem-type> with the file system type you want to use, such as ext4 or NTFS, and /dev/sdXY with the partition name
-
Mount partitions
After creating and formatting partitions, you need to mount them to make them accessible to the system. To mount a partition, you need to specify the partition and the mount point.
For example, to mount a partition /dev/sda1 to the /mnt/data directory, use the following command:
sudo mount /dev/sda1 /mnt/data
With this command, the partition will be mounted to the designated mount point. To automatically mount the partition at startup time, you may also add it to the /etc/fstab file.
-
Resize partitions
If you need to enlarge an existing partition, use the parted command to resize the partition and the resize2fs command to resize the file system.
For example, to resize a partition /dev/sda1 to 20 GB, use the following steps:
Unmount the partition using the command sudo umount /dev/sda1.
Use the command sudo parted /dev/sda resize part 1 20GB to resize the partition to 20 GB.
Use the command sudo resize2fs /dev/sda1 to resize the file system to match the partition size.
-
Delete partitions
To delete a partition, use the partitioning tool of your choice and follow these steps:
Select the partition you want to delete.
Delete the partition using the command d.
Write the changes to disk using the command w.
For example, to delete a partition /dev/sda1 using fdisk, use the following steps:
Run the command sudo fdisk /dev/sda to start fdisk.
Press the key d to delete a partition.
Specify the partition number you want to delete, such as 1 or 2.
Press the key w to write the changes to disk and exit fdisk.
-
Backup and restore partitions
Before making any modifications, it is generally a good idea to backup your partitions. To generate disc images of your partitions, use programmes like dd or part clone.
For example, to create a backup of a partition /dev/sda1 to a file backup.img, use the following command:
javascriptCopy code
sudo dd if=/dev/sda1 of=backup.img
To restore the backup, use the following command:
javascriptCopy code
sudo dd if=backup.img of=/dev/sda1
Note that these commands can take a long time to complete, depending on the size of the partition.
Conclusion
Overall, managing storage and partitions in Debian 11 requires some knowledge of the available tools and commands. Make sure to back up your data before making any changes and double-check your commands before executing them to avoid any data loss.

As you can see, the /boot partition on Debian 11 or other Linux distributions should have a minimum size of between 256 MB and 512 MB. A dedicated /boot partition can frequently help your system by separating potential issues.
All partitions can be erased, except for the EFI partition and the partition containing the C drive, but this is not advised. To make room for other systems, I advise compressing the space on the C drive.
All the data in a partition is lost if it is deleted or formatted. A deleted partition’s drive space will be designated as raw or unformatted. Either the existing partitions need to be extended or a new partition can be created to use the available space.
