On small systems (like a desktop), instead of having to estimate at installation time how big a partition might need to be, LVM allows filesystems to be easily resized as needed. Performing consistent backups by taking snapshots of the logical volumes. Encrypting multiple physical partitions with one password.
The system pools LEs into a volume group (VG). The pooled LEs can then be concatenated together into virtual disk partitions called logical volumes or LVs. Systems can use LVs as raw block devices just like disk partitions: creating mountable file systems on them, or using them as swap storage.
System administrators use a program called a partition editor to create, resize, delete, and manipulate the partitions. [3] Partitioning allows the use of different filesystems to be installed for different kinds of files. Separating user data from system data can prevent the system partition from becoming full and rendering the system unusable.
GParted is used for creating, deleting, [3] resizing, [4] moving, checking, and copying disk partitions and their file systems. This is useful for creating space for new operating systems, reorganizing disk usage, copying data residing on hard disks, and mirroring one partition with another (disk imaging). It can also be used to format a USB drive.
If there is more than one extended partition in a partition table, only the logical drives in the first recognized extended partition type are processed. Some late versions of the DR-DOS IBMBIO.COM provide a preboot config structure, holding bit flags to select (beside others) between various drive letter assignment strategies.
The system partition is the disk partition that contains the operating system folder, known as the system root. By default, in Linux, operating system files are mounted at / (the root directory). In Linux, a single partition can be both a boot and a system partition if both /boot/ and the root directory are in the same partition.
The VERITAS File System (or VxFS; called JFS and OnlineJFS in HP-UX) is an extent-based file system. It was originally developed by VERITAS Software. [1] Through an OEM agreement, VxFS is used as the primary filesystem of the HP-UX operating system. With on-line defragmentation and resize support turned on via license, it is known as OnlineJFS.

F2FS (Flash-Friendly File System) is a flash file system initially developed by Samsung Electronics for the Linux kernel. [ 5 ] The motive for F2FS was to build a file system that, from the start, takes into account the characteristics of NAND flash memory -based storage devices (such as solid-state disks , eMMC , and SD cards), which are ...
