Software Map

libferris is a virtual filesystem that exposes hierarchical data of all kinds through a common C++ interface. Access to data is performed using C++ IOStreams and metadata is available as key-value pairs through the Extended Attributes (EA) interface. Rich support for filesystem indexing is included to provide timely search results for well into millions of files. Ferris uses a plugin API to handle a large range of data sources, metadata, and index and search strategies. Filesystems include file:// with monitoring, XML (mount an XML file as a filesystem), relational databases, ISAM databases (Berkeley db, tdb, gdbm, eet et al), xmldb, LDAP, Applications (Evolution, Firefox, Emacs), HTTP, FTP, sockets, and RDF (from XML, binary, soprano). EA generators include image, audio, and animation decoders.

AFS is a distributed filesystem which offers a client-server architecture, transparent data migration abilities, scalability, a single namespace, and integrated ancillary subsystems.

CDfs is a file system for Linux systems that exports' all tracks and boot images on a CD as normal files. These files can then be mounted (e.g. for ISO and boot images), copied, played (audio tracks), etc. The primary goal for developing this file system was to unlock' information in old ISO sessions. The file system also allows you to access data on faulty multi session disks, e.g. disks with multiple single sessions instead of a multi session.

Bonnie++ is based on the Bonnie hard drive benchmark by Tim Bray. The most notable features that have been added are support for >2G of storage and testing operations involving thousands of files in a directory. This program is used by ReiserFS developers, but can be useful for anyone who wants to know how fast their hard drive or file system is. It now includes ZCAV in the package. This program tests the performance of different zones on the hard drive. ZCAV has been released separately before but will now only be released as part of the Bonnie++ suite.

openMosix is a a set of extensions to the standard Linux kernel allowing you to build a cluster of out of off-the-shelf PC hardware. openMosix scales perfectly up to thousands of nodes. You do not need to modify your applications to benefit from your cluster (unlike PVM, MPI, Linda, etc.). Processes in openMosix migrate transparently between nodes and the cluster will always auto-balance.

FSlint is a toolkit to find various forms of lint on a filesystem. At the moment it reports duplicate files, bad symbolic links, troublesome file names, empty directories, non stripped executables, temporary files, duplicate/conflicting (binary) names, and unused ext2 directory blocks.

The ext2fsprogs package contains essential ext2 filesystem utilities which consists of e2fsck, mke2fs, debugfs, dumpe2fs, tune2fs, and most of the other core ext2 filesystem utilities.

Lustre is a novel storage and filesystem architecture and implementation suitable for very large clusters. It is a next-generation cluster filesystem that is currently running on clusters that have tens of thousands of nodes, petabytes of storage, and move hundreds of GB/sec.

FAM, the File Alteration Monitor, provides an API which applications can use to be notified when specific files or directories are changed. It comes in two parts: fam, the daemon which listens for requests and delivers notification, and libfam, a library which client applications can use to communicate with fam.
