Learn how to – Top Tools To View Disk Partitions and Disk Usage on Linux.

The creation and deletion of partitions is a regular task in Linux. This is due to the fact that storage devices such as hard drives and USB disks need to be structured in a certain way before being used. For example, before installing the system or creating any files, a file system must exist. Similarly, a filesystem can only exist if a partition has been created.

Disk partitioning can be defined as the process of dividing a disk into single or multiple logical areas. These divisions are often referred to as partitions. Partitions work as isolated sections where each section behaves as its own hard drive. Once a partition has been created, the disk will store the information about the location and size of partitions in the partition table. In other terms, a partition table describes the layout of partitions of a hard drive. Normally, there are two partition table standards. These are:

MBR (Master Boot Record): It is also referred to as ms-dos. This partitioning scheme is normally found on older computers. It only four partitions are allowed and can have a maximum disk size of 2 TB. The MBR also contains a boot loader that is written in the initial sectors of the drive.
GPT (GUID Partition Table): This is widely used nowadays. As opposed to MBR, GPT doesn’t contain a boot loader and can have up to 128 partitions (128-bit entries). It also supports the MBR section for backward compatibility.

Disk partitioning is vital as it helps do the following:

To upgrade Hard Disk and incorporate a new Hard Disk into the system
Dual Booting, where users can have Multiple Operating Systems on the same system.
Efficient disk management where each partition can be managed separately.
Work with different File Systems using the same system
To ensure backup and security.

Traditionally, to partition MBR disks, the fdisk tool is used. However, with technological advancements, fdisk was developed to understand the GPT format. There are also several other tools that can be used to manage disk partitions on Linux. In this guide, we will learn about the top tools to view Disk Partitions and Disk Usage on Linux.

1. Fdisk

Fdisk also known as the fixed disk is the most widely used tool when viewing Disk Partitions and Disk Usage on Linux systems. It helps users get all the detailed information about partitions and can also be used to monitor, create, delete, move, and copy any partition in your Linux system. Fdisk supports GPT, MBR, Sun, SGI, and BSD partition tables.

This tool can be used in the following ways:

View all disk partitions

To view all the partitions on your system, use the command with the -l argument as shown:

sudo fdisk -l

Sample Output:

View details about specific partitions

You can also view details about a given partition by providing the name of the partition. For example:

sudo fdisk -l /dev/sda

Sample Output:

Create a partition

Fdisk provides a number of commands that can be used to manage partitions. To get all the available commands, specify the hard disk name and proceed as shown:

sudo fdisk /dev/sda

Sample Output:

The partitions in the hard disk will be printed as shown above.

To create new a partition, provide the disk name and type “n”. For this demonstration, I will use a secondary hard disk /dev/sdb identified using sudo fdisk -l

sudo fdisk /dev/sda

To create a partition, type n and set the partition type as shown:

Command (m for help): n
Partition type
   p   primary (0 primary, 0 extended, 4 free)
   e   extended (container for logical partitions)
Select (default p): p

Set the partition number and sectors

Partition number (1-4, default 1): 1
First sector (2048-20971519, default 2048): Press Enter
Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-20971519, default 20971519): Press Enter
Created a new partition 1 of type 'Linux' and of size 10 GiB.

Command (m for help):

To verify the creation, print the partition tables;

Command (m for help): p
Disk /dev/sdb: 10 GiB, 10737418240 bytes, 20971520 sectors
Disk model: QEMU HARDDISK   
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x6602bb9a

Device     Boot Start      End  Sectors Size Id Type
/dev/sdb1        2048 20971519 20969472  10G 83 Linux

Command (m for help):

Now apply the changes and exit

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.

Delete a partition

To delete a partition, provide the disk name:

sudo fdisk /dev/sdb

Use the “d” to delete the partition.

Command (m for help): d
Selected partition 1
Partition 1 has been deleted.

Command (m for help):

Apply the changes and exit using “w“:

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.

2. GDisk

GDisk is a DOS command-line utility, that operates in a similar way to fdisk. GDisk performs everything you can do with FDisk but has some capabilities that FDisk does not. Some of the capabilities include the on-the-fly formatting, increased performance, better partition management e.t.c

The basic operations performed by GDisk are:

View disk partitions

The command used to view details about a given disk for example /dev/sda is:

sudo gdisk -l /dev/sda

Sample Output:

List all the available commands

To get a list of the available commands, use “?” as shown;

$ sudo gdisk /dev/sda
GPT fdisk (gdisk) version 1.0.5

Partition table scan:
......
Command (? for help): ?
b	back up GPT data to a file
c	change a partition's name
d	delete a partition
i	show detailed information on a partition
l	list known partition types
n	add a new partition
o	create a new empty GUID partition table (GPT)
p	print the partition table
q	quit without saving changes
r	recovery and transformation options (experts only)
s	sort partitions
t	change a partition's type code
v	verify disk
w	write table to disk and exit
x	extra functionality (experts only)

Command (? for help):

As seen, the commands resemble those used in FDisk.

Create a new GPT partition table

To create a new GPT partition table, provide the disk name. For example:

sudo gdisk /dev/sdb

Use the “n” command to create a new partition.

Command (? for help): n

The operation has completed successfully.

Delete a partition

To delete a partition, use “d” as shown;

$ sudo gdisk /dev/sdb
GPT fdisk (gdisk) version 1.0.5

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.

Command (? for help): d

Once the partition has been selected, write the changes:

Command (? for help): w
inal checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!

Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT) to /dev/sdb.
The operation has completed successfully.

3. Parted

Parted is also a widely used command when displaying and manipulating disk partitions. This is because it understands multiple partition table formats, such as MBR and GPT. It can be used to add, resize, remove partitions, reorganizing disk usage and copy data to partitions.

The common use cases are:

Listing Partitions

The command for this is:

sudo parted -l

Sample output:

Create a new partition

Open the disk. For example /dev/sdb

sudo parted /dev/sdb

Sample Output:

        copyright information of GNU Parted

To create a new partition, you can go for either GPT or MSDOS partition table. For GPT, proceed as shown:

##For GPT
(parted) mklabel gpt

##For MSDOS
(parted) mklabel msdos

For this guide, I will go for the MSDOS partition table although the procedure is similar for GPT.

Warning: The existing disk label on /dev/sdb will be destroyed and all data on
this disk will be lost. Do you want to continue?
Yes/No? yes

Once the partition table has been created, we will proceed and create a partition now:

(parted) mkpart

Proceed as shown:

Partition type?  primary/extended? primary                                
File system type?  [ext2]? ext4  
Start?
Start? 1
End? 9090

The start and end values define the size of the partition in MBs. In this case, it is almost 10GB.

To verify the creation, use the command:

(parted) print                                                            
Model: ATA QEMU HARDDISK (scsi)
Disk /dev/sdb: 10.7GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags: 

Number  Start   End     Size    Type     File system  Flags
 1      1049kB  9090MB  9089MB  primary  ext4         lba

(parted)

How to resize partitions

It is possible to shrink and extend partitions using the parted command.

To shrink a partition, use the command below. Remember data can be lost when shrinking the partition.

(parted) resizepart                                                       
Partition number? 1          
End?  [9090MB]? 5000                                                      
Warning: Shrinking a partition can cause data loss, are you sure you want to
continue?
Yes/No? yes

Verify the changes

Model: ATA QEMU HARDDISK (scsi)
Disk /dev/sdb: 10.7GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags: 

Number  Start   End     Size    Type     File system  Flags
 1      1049kB  5000MB  4999MB  primary

(parted)

To extend the partition:

(parted) resizepart                                                       
Partition number? 1                                                       
End?  [5000MB]? 9080

Verify:

(parted) print
Model: ATA QEMU HARDDISK (scsi)
Disk /dev/sdb: 10.7GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags: 

Number  Start   End     Size    Type     File system  Flags
 1      1049kB  9080MB  9079MB  primary

(parted)

Delete partition

To delete a partition, use the rm command and the partition number. For example:

(parted) rm
Partition number? 1                                                       
(parted)

Verify:

(parted) print                                                            
Model: ATA QEMU HARDDISK (scsi)

4. du, ncdu

Du and ncdu are famous commands to track disk usage. ncdu originates from NCurses Disk Usage and is mainly based on du(online tool) commands.

The du tool can be started with the command:

$ du 
8	./.npm/_cacache/index-v5/22/e3
60	./.npm/_cacache/index-v5/22
8	./.npm/_cacache/index-v5/fa/9f

4	./.gnupg/private-keys-v1.d
16	./.gnupg
4	./Videos
8	./.ssh
4	./Downloads
....

You can get the information above in a more human-readable format;

$ du -h

8.0K	./.npm/_cacache/index-v5/ff/89
36K	./.npm/_cacache/index-v5/ff
....

The values on the left indicate the disk space utilized by the files.

To list the sizes of all files and directories, use the command -a or --allFor example:

$ du -ah 
44K	./frontend/src/types/actions
556K	./frontend/src/types
4.0K	./frontend/src/index.html.ejs
4.0K	./frontend/src/pages/UnAuthorized/index.tsx
8.0K	./frontend/src/pages/UnAuthorized
4.0K	./frontend/src/pages/MySettings/index.tsx
8.0K	./frontend/src/pages/MySettings
4.0K	./frontend/src/pages/MetricApplication/index.tsx
8.0K	./frontend/src/pages/MetricApplication
4.0K	./frontend/src/pages/Metrics/index.tsx
8.0K	./frontend/src/pages/Metrics

4.0K	./frontend/src/pages/TraceDetail/constants.ts
12K	./frontend/src/pages/TraceDetail
4.0K	./frontend/src/pages/GettingStarted/Section.tsx
....

Once installed, ncdu can be launched from the terminal with the command:

ncdu

Here, you can use the arrow up and down keys to navigate through the different directories. If you press Enter, you will move into the selected directory.

To exit, press”q“.

It takes quite some time when scanning large directories. For example, starting the tool at the root it will have many files to analyze.

Using the -o option, you avoid preparing a report and instead save all the collected data. For example:

$ sudo ncdu -o /tmp/dureport
/home/ubuntu/signoz/deploy/do...pSort.proj/msgOperation.dict.mrk2    28753 files

You can now view the file:

$ head -11 /tmp/dureport
[1,1,{"progname":"ncdu","progver":"1.14.1","timestamp":1667043990},
[{"name":"/home/ubuntu","asize":4096,"dsize":4096,"dev":2053,"ino":1446098},
[{"name":"Public","asize":4096,"dsize":4096,"ino":1705159}],
[{"name":"Pictures","asize":4096,"dsize":4096,"ino":1705162}],
[{"name":"Music","asize":4096,"dsize":4096,"ino":1705161}],
{"name":".sudo_as_admin_successful","ino":1443137},
{"name":".bashrc","asize":3771,"dsize":4096,"ino":1450156},
{"name":".profile","asize":807,"dsize":4096,"ino":1450157},
