In computer file systems, a cluster (sometimes also called allocation unit or block) is a unit of disk space allocation for files and directories. To reduce the overhead of managing on-disk data structures, the filesystem does not allocate individual disk sectors by default, but contiguous groups of sectors, called clusters.
The collection of computer hosts that comprise a OneFS System is referred to as a "cluster". A computer host that is a member of a OneFS cluster is referred to as a "node" (plural "nodes"). The nodes that comprise a OneFS System must be connected by a high performance, low-latency back-end network for optimal performance.
AcetoneISO also supports Direct Access Archive (*.daa) images because it uses the non-free and proprietary PowerISO Linux software as a backend while converting images to ISO. In recent releases (as of 2010), AcetoneISO also gained native support at blanking CD/DVD optical discs and burn ISO/CUE/TOC images to CD-R/RW and DVD-+R/RW (including DL ...
The compression algorithm and cluster size is specified on a per-file basis. Directories can also be marked for compression, in which case every newly created file in the directory will be automatically compressed with the same cluster size and the same algorithm that was specified for the directory. e2compr is not a new file system.
Linux The Oracle Cluster File System ( OCFS , in its second version OCFS2 ) is a shared disk file system developed by Oracle Corporation and released under the GNU General Public License . The first version of OCFS was developed with the main focus to accommodate Oracle's database management system that used cluster computing .
In computing, the Global File System 2 (GFS2) is a shared-disk file system for Linux computer clusters. GFS2 allows all members of a cluster to have direct concurrent access to the same shared block storage, in contrast to distributed file systems which distribute data throughout the cluster. GFS2 can also be used as a local file system on a ...
The most common type of clustered file system, the shared-disk file system – by adding mechanisms for concurrency control – provides a consistent and serializable view of the file system, avoiding corruption and unintended data loss even when multiple clients try to access the same files at the same time.
OpenSSI is an open-source single-system image clustering system. It allows a collection of computers to be treated as one large system, allowing applications running on any one machine access to the resources of all the machines in the cluster.
