muser lists processes which have a given directory (or cwd if not specified) as a parent of their current working directory (thus making it impossible to unmount that directory if it is a mount point). This script has overlapping functionality with the fuser program from the psmisc package, but has the advantage that it works on SMB mounts. Additionally, it provides a color, formatted listing of process IDs, executable names, current working directories, and the command lines used to run the programs. It works with varying-sized /proc/*/cwd fields.
Unison is a file-synchronization tool for Unix and Windows. It allows two copies of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other. Unison can deal with updates to both replicas of a distributed directory structure. Updates that do not conflict are propagated automatically. Conflicting updates are detected and displayed. Unison can communicate through a direct socket link or through an rsh/ssh tunnel. It uses network bandwidth efficiently.
ClusterNFS is a set of patches for the "Universal NFS Daemon" (UNFSD) to allow multiple clients to nfs mount the same root filesystem by providing "tagged" filenames. When a client requests the file "/path/filename", the ClusterNFS server checks for the existence of files of the form "/path/filename$$TAG=value$$". If such a file exists and the client has a matching value for KEY, this file is returned. If the client does not have a matching value or no such file exists, the file request proceeds as normal. Currently supported keys include HOST (hostname), IP (IP number), CLIENT (matches any nfs client) and CREATE (for "tagged" creation of files).
fistgen is the FiST language code generator, used to create stackable file systems out of templates and a high-level language. This package comes with stackable file system templates for Linux, Solaris, and FreeBSD. It also contains several sample file systems built using the FiST language: an encryption file system, a compression file system, and more - all of which are written as portable stackable file systems.
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.
