In Linux, Logical Volume Manager (LVM) is a device mapper framework that provides logical volume management for the Linux kernel. Most modern Linux distributions are LVM-aware to the point of being able to have their root file systems on a logical volume .
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices.It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots.
With implementations that are solely volume management, such as Core Storage and Linux LVM, separating and abstracting away volume management from the file system loses the ability to easily make storage decisions for particular files or directories. For example, if a certain directory (but not the entire file system) is to be permanently moved ...
LLVM, also called LLVM Core, is a target-independent optimizer and code generator. [5] It can be used to develop a frontend for any programming language and a backend for any instruction set architecture.

Operating within the Linux kernel's block layer, DRBD is essentially workload agnostic. A DRBD can be used as the basis of: A conventional file system (this is the canonical example), a shared disk file system such as GFS2 or OCFS2, [12] [13] another logical block device (as used in LVM, for example),

XFS was ported to the Linux kernel in 2001; as of June 2014, XFS is supported by most Linux distributions; Red Hat Enterprise Linux uses it as its default file system. XFS excels in the execution of parallel input/output (I/O) operations due to its design, which is based on allocation groups (a type of subdivision of the physical volumes in ...
