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 ...
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 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.
Ceph (pronounced / ˈ s ɛ f /) is a free and open-source software-defined storage platform that provides object storage, [7] block storage, and file storage built on a common distributed cluster foundation. Ceph provides distributed operation without a single point of failure and scalability to the exabyte level.
Disk Usage Analyzer is a graphical disk usage analyzer for GNOME. It was part of GNOME Core Applications, [2] but was split off for GNOME 3.4. It was originally named Baobab after the Adansonia tree. The software gives the user a menu-driven, graphical representation of what is on a disk drive. [3]
With the standard hard disk sector size of 512 bytes, this gives a maximum of 32 KB cluster size, thereby fixing the "definitive" limit for the FAT16 partition size at 2 GB for sector size 512. On magneto-optical media, which can have 1 or 2 KB sectors instead of 0.5 KB, this size limit is proportionally larger.
Ganglia software is bundled with enterprise-level Linux distributions such as Red Hat Enterprise Linux (RHEL) or the CentOS repackaging of the same. Ganglia grew out of requirements for monitoring systems by Berkeley (University of California) but now sees use by commercial and educational organisations such as Cray, MIT, NASA and Twitter.
The Linux version has no graphical user interface, although extensions created to simplify usage under Linux. [48] [49] In the Linux version of Hard Disk Sentinel, it still is limited like the DOS version. The Linux version can only be used in the Linux Terminal, and it also does not allow you to run any disk tests are repairs. You can also ...
