A Brick is - expressed by combining a server with an export directory in the - following format: - - `SERVER:EXPORT` - - For example: - - `myhostname:/exports/myexportdir/` - -Cluster -: A cluster is a group of linked computers, working together closely - thus in many respects forming a single computer. - -Distributed File System -: A file system that allows multiple clients to concurrently access - data over a computer network. - -Filesystem -: A method of storing and organizing computer files and their data. - Essentially, it organizes these files into a database for the - storage, organization, manipulation, and retrieval by the computer's - operating system. - - Source: [Wikipedia][] - -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. - - Source: [Wikipedia][1] - -Geo-Replication -: Geo-replication provides a continuous, asynchronous, and incremental - replication service from site to another over Local Area Networks - (LAN), Wide Area Network (WAN), and across the Internet. - -glusterd -: The Gluster management daemon that needs to run on all servers in - the trusted storage pool. - -Metadata -: Metadata is data providing information about one or more other - pieces of data. - -Namespace -: Namespace is an abstract container or environment created to hold a - logical grouping of unique identifiers or symbols. Each Gluster - volume exposes a single namespace as a POSIX mount point that - contains every file in the cluster. - -Open Source -: Open source describes practices in production and development that - promote access to the end product's source materials. Some consider - open source a philosophy, others consider it a pragmatic - methodology. - - Before the term open source became widely adopted, developers and - producers used a variety of phrases to describe the concept; open - source gained hold with the rise of the Internet, and the attendant - need for massive retooling of the computing source code. - - Opening the source code enabled a self-enhancing diversity of - production models, communication paths, and interactive communities. - Subsequently, a new, three-word phrase "open source software" was - born to describe the environment that the new copyright, licensing, - domain, and consumer issues created. - - Source: [Wikipedia][2] - -Petabyte -: A petabyte (derived from the SI prefix peta- ) is a unit of - information equal to one quadrillion (short scale) bytes, or 1000 - terabytes. The unit symbol for the petabyte is PB. The prefix peta- - (P) indicates a power of 1000: - - 1 PB = 1,000,000,000,000,000 B = 10005 B = 1015 B. - - The term "pebibyte" (PiB), using a binary prefix, is used for the - corresponding power of 1024. - - Source: [Wikipedia][3] - -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. - -RAID -: Redundant Array of Inexpensive Disks (RAID) is a technology that - provides increased storage reliability through redundancy, combining - multiple low-cost, less-reliable disk drives components into a - logical unit where all drives in the array are interdependent. - -RRDNS -: Round Robin Domain Name Service (RRDNS) is a method to distribute - load across application servers. RRDNS is implemented by creating - multiple A records with the same name and different IP addresses in - the zone file of a DNS server. - -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. - -Volfile -: Volfile is a configuration file used by glusterfs process. Volfile - will be usually located at `/var/lib/glusterd/vols/VOLNAME`. - -Volume -: A volume is a logical collection of bricks. Most of the gluster - management operations happen on the volume. - - [Wikipedia]: http://en.wikipedia.org/wiki/Filesystem - [1]: http://en.wikipedia.org/wiki/Filesystem_in_Userspace - [2]: http://en.wikipedia.org/wiki/Open_source - [3]: http://en.wikipedia.org/wiki/Petabyte |
