Gluster 3.2: Terminologies

From GlusterDocumentation

The terms defined here help you understand the concepts in this document.

Term Description
Distributed File System A file system that allows multiple clients to concurrently access data over a computer network.
FUSE Filesystem in Userspace (FUSE) is a loadable kernel module for Unix-like computer operating systems that lets non-privileged users create their own file systems without editing kernel code. This is achieved by running file system code in user space while the FUSE module provides only a "bridge" to the actual kernel interfaces.
glusterd Gluster management daemon that needs to run on all servers in the trusted storage pool.
Gluster Native Client Gluster Native Client is a POSIX conformant, FUSE-based client running in user space.
POSIX Portable Operating System Interface [for Unix] is the name of a family of related standards specified by the IEEE to define the application programming interface (API), along with shell and utilities interfaces for software compatible with variants of the Unix operating system. Gluster exports a fully POSIX compliant file system.
Trusted Storage Pool A storage pool is a trusted network of storage servers. When you start the first server, the storage pool consists of that server alone.
Userspace Applications running in user space don’t directly interact with hardware, instead using the kernel to moderate access. Userspace applications are generally more portable than applications in kernel space. Gluster is a user space application.
