![]() 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. I personally prefer blkid.Formatting and partitioning disks is a key aspect of Linux administration. To find the IDs, we can use `ls` or blkid. So before we continue to the next step we need to find the UUID s of the drive/s that you’re mounting. There are many ways we can use to mount drives using fstab but the best way is to use UUID to map the drives.You have given read/write permissions to your group and others. Number 744 means you have assigned read/write/execute permissions to your user account.To do that, we can use the chmod command. After owning the folder we still can’t write to the folder so we need to give the folder read and write permissions.-R switch makes the command operate on a file or a directory recursively.Ex: if your user name is ben then your user group will be ben. User group is similar to your user name.So we have to get ownership of the folder before continuing to other steps. Due to using sudo the new folder belongs to root not to your user. We still can’t use the new folder we created in the above step.You have to use sudo otherwise you will get a permission denied error.To make the new folder we can use the mkdir command. You can use /mnt or /run/media (Becarfule using this because It is usually a temporary file system not intended to hold persistent data) or any other location but I’m going to use `/mnt` for this tutorial. Now we have to make a new folder as the mount point for our external drive. After identifying the drive label make note of it or remember the correct label.So don’t panic it will get listed once we finish the mounting steps. In your case, you would only see the drive label and the partition without a mount point in front of the partition details. The drives from sdc below are my externals. In the above image I already have my externals mounted.The three letters followed by a number under the main three letters above the tree view are the partitions.In the above image the main three letters at the top of each tree view is the device label.
