Server Disk Drive Tools Linux Format
1. fdisk

The fdisk command can display the partitions and details like file system type, model, zise. In Ubuntu 20.04 report the size of each partitions, but not in all Linux distributions!

@ sudo fdisk -l

2. sfdisk

It is another utility with a similar purpose to fdisk command, but with more features.
Ex. Can display the size of each partition in bytes:

@ sudo sfdisk -s
/dev/loop0:     56692
/dev/loop1:     56712
/dev/loop2:     69376
/dev/loop3:     30600
/dev/loop4:     31808
/dev/loop5:     72984
/dev/nvme0n1: 244198584
/dev/sda: 250059096
/dev/sdb: 2930266584
/dev/sdc: 1953481728
/dev/sdd: 3907018584
/dev/sde: 2930266584
/dev/mapper/ubuntu--vg-ubuntu--lv: 121311232
total: 12336920564 blocks
3. cfdisk

is a Linux partition editor with an interactive user interface. It can be used to list existing partitions, as well as to create or modify them.

Here is an example of how to use cfdisk command to list the partitions on disk /dev/nvme0n1

@ sudo cfdisk /dev/nvme0n1

cfdisk-utility disk ubuntu-server-linux

4. parted

is another command line utility for listing partitions and modifying them if necessary.
Here is an example of using parted command that lists the partition details:

@ sudo parted -l
Model: ATA Samsung SSD 850 (scsi)
Disk /dev/sda: 256GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

Number  Start   End    Size   File system  Name     Flags
 1      1049kB  256GB  256GB  ext4         primary

Model: WD Elements 10B8 (scsi)
Disk /dev/sdc: 2000GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

Number  Start   End     Size    Type     File system  Flags
 1      1049kB  2000GB  2000GB  primary  ntfs

Model: ATA HGST HUS726040AL (scsi)
Disk /dev/sdd: 4001GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

 1      1049kB  4001GB  4001GB  ext4         primary

Model: Samsung SSD 970 EVO 250GB (nvme)
Disk /dev/nvme0n1: 250GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

Number  Start   End     Size    File system  Name  Flags
 1      1049kB  538MB   537MB   fat32              boot, esp
 2      538MB   1612MB  1074MB  ext4
 3      1612MB  250GB   248GB

With parted you can delete, modify, create partitions on a physical disk:

@ sudo parted -h
Usage: parted [OPTION]... [DEVICE [COMMAND [PARAMETERS]...]...]
Apply COMMANDs with PARAMETERS to DEVICE.  If no COMMAND(s) are given, run in
interactive mode.

OPTIONs:
  -h, --help                      displays this help message
  -l, --list                      lists partition layout on all block devices
  -m, --machine                   displays machine parseable output
  -s, --script                    never prompts for user intervention
  -v, --version                   displays the version
  -a, --align=[none|cyl|min|opt]  alignment for new partitions

COMMANDs:
  align-check TYPE N                       check partition N for TYPE(min|opt) alignment
  help [COMMAND]                           print general help, or help on COMMAND
  mklabel,mktable LABEL-TYPE               create a new disklabel (partition table)
  mkpart PART-TYPE [FS-TYPE] START END     make a partition
  name NUMBER NAME                         name partition NUMBER as NAME
  print [devices|free|list,all|NUMBER]     display the partition table, available devices, free space, all found partitions, or a particular partition
  quit                                     exit program
  rescue START END                         rescue a lost partition near START and END
  resizepart NUMBER END                    resize partition NUMBER
  rm NUMBER                                delete partition NUMBER
  select DEVICE                            choose the device to edit
  disk_set FLAG STATE                      change the FLAG on selected device

A single command line to create an ext4 primary partition on /dev/sdd disk:

@ sudo parted /dev/sdd -a opt mkpart primary ext4 2048s 4001GB

Previously, however, it is necessary for the existing partitions to be deleted using the rm command from the parted, the existing space must be sufficient for the above command, approximately 4Tb.

Use this command carefully because if you choose the wrong disk you worked on or delete the wrong partitions, you may lose all information!

5. df

is a disk utility that prints details about mounted file systems. The list generated by df command even includes file systems that are not “real” disk partitions, like tmpfs, udev :

@ df -h
Filesystem                         Size  Used Avail Use% Mounted on

Use linux grep command to filter out real hard disk partitions/file systems,

Here’s an example of how to find only file systems that are actual devices or partitions and start with a /dev :

@ df -h | grep ^/dev
/dev/mapper/ubuntu--vg-ubuntu--lv  114G   65G   43G  61% /
/dev/nvme0n1p2                     976M  199M  711M  22% /boot

8. mke2fs

is used to create an ext2, ext3, or ext4 filesystem, usually in a disk partition.

example with format disk partition in ext4 type:

@ mke4fs -t ext4 /dev/sdd1

this last command is similar with next mkfs command:

@ mkfs.ext4 /dev/sdd1
9. mkfs

is used to format a Linux file system on a device, usually a hard disk partition, and actuality is simply a front-end for the various file system builders (mkfs.fstype) available under Linux OS.

@ mkfs.ext2 /dev/sda1
@ mkfs.ext3 /dev/sdb1
@ mkfs.ext4 /dev/sdd1
10. tune2fs

adjust tunable file system parameters on the ext2, ext3 or ext4 Linux file systems.

The current values of these options can be displayed by using the -l option :

@ tune2fs -l /dev/sdd1
