2/3/2024 0 Comments Ubuntu disk managerThe general syntax for formatting a disk partition in Linux is: mkfs. Now that our disk is fully partitioned, we can format the newly created sda2 partition. We can see our newly created partition sda by running the command lsblk /dev/sda. The output should look similar to:įdisk will then exit and you'll be back at Linux shell. At the Command (m for help): prompt, input a w to write the changes to the Linux system. You may enter p to see a partition table and make sure your changes are correct:Īs you can see, we now have two partitions on the /dev/sda disk. This would enable us to create multiple partitions on the drive. Note that if we wanted to create a smaller partition, we could use a smaller gap between our first and last block. We'll press enter to accept the default first sector, and then get prompted for a last sector.Īgain, we'll press enter to accept the default and fdisk will create the partition. We'll use the default of 2 and then get prompted for a sector number. Then, we'll be prompted to give a partition number. We'll press enter to select the default and create a new primary partition. It shows that the disk that is mounted on /dev/sda directory has one primary partition that is formatted and being used at the moment. That will launch the interactive fdisk utility and you should see output similar to:Īt the Command (m for help): prompt, type n to create a new partition. ![]() To begin, we'll open our drive in fdisk with this command: fdisk /dev/sda Note: If you're partitioning a disk that is currently mounted, first unmount it with the command `umount. You can modify these options based on your requirements. We will create a primary partition and use the default partition number, first sector, and last sector that fdisk selects. For our case, we'll assume our disk is mounted on /dev/sda. There are several ways to partition disks in Linux, including parted and gparted, but we'll focus on the popular fdisk utility here. If you want to see information like file system types, disk labels and UUIDs, use the command lsblk -f. Partitions have a TYPE of part and are nested under their disks in the output like sda1 in our example. To view existing partitions in Linux, use the lsblk command. #How to view existing partitions in Linuxīefore you create a new partition, you may want to view your existing partitions. The output will include additional identifying information such as the product, size, vendor, bus, and logical name (the device’s path), similar to this: If you need more information to properly identify your drives, use lshw -class disk. "-I 8" specifies a the kernel device number for block devices and the -d excludes partitions. If you need a more refined view of your disks, use the lsblk -I 8 -d command. The fsdisk output above included loop devices which are logical pseudo-devices, but not real disks. To view available disks in Linux, run this command: fdisk -l | grep "Disk /" Backups of any data you don't want to lose (optional).We are going to use a server with custom partitioning layout from Cherry Servers. An available disk you want to format and partition.Access to the terminal of a Linux system.Now let's dive into partitioning and formatting disks on a Linux system. #How to Partition and Format Disk Drives on Linux This logical separation can be useful for a variety of scenarios, including limiting the growth of a filesystem and installing multiple operating systems on a single drive. Creating a partition on a drive logically separates it from other partitions. Common examples of storage devices include hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, and SD cards. Partitioning is the process of creating logical boundaries on a storage device. Many *nix and Windows operating systems support FAT32. It supports a 4GB max file size and a 2TB max volume size. FAT32 - Is an older filesystem, but you may still see it used in the wild.The Linux kernel added full support for NTFS in version 5.15. ![]() It supports 8PB max volume and file sizes. NTFS - NTFS is a popular filesystem developed by Microsoft.It is not supported on Windows by default. It supports file sizes up to 16TB and volumes up to 1EB. Ext4 - Ext4 is a common default filesystem on many modern Linux distributions.Some of the most popular filesystems for Linux include: ![]() Formatting deletes the existing data on the partition and sets up a filesystem. #What is disk formatting in Linux?ĭisk formatting is the process that prepares a storage partition for use. This article will walk you through how you can partition and format disks to complete common Linux administration tasks. You can use formatting and partitioning to address use cases like prepping storage media for use, addressing space issues with existing disks, or wiping a filesystem. Formatting and partitioning disks is a key aspect of Linux administration.
