-
-
-
-
-!! 1.12 Introduction to logging/journaling filesystems
-
-
-
-
-
-
-File systems update their structural information (called
-metadata) by synchronous writes. Each metadata update may require many
-separate writes, and if the system crashes during the write sequence, metadata
-may be in inconsistent state.
-
-
-At the next boot the filesystem check utility (called fsck) must walk
-through the metadata structures, examining and repairing them.
-This operation takes a very very long time on large filesystems.
-And the disk may not contain sufficient information
-to correct the structure. This results in misplaced or removed files.
-
-
-
-
-
-A journaling file system uses a separate area called a log or journal.
-Before metadata changes are actually performed, they are logged to this separate
-area. The operation is then performed. If the system crashes during
-the operation, there is enough information in the log to "replay" the log
-record and complete the operation.
-
-
-This approach does not require a full
-scan of the file system, yielding very quick filesystem check time on
-large file systems,
-generally a few seconds for a multiple-gigabyte file system. In addition,
-because all information for the pending operation is saved, no removals
-or lost-and-found moves are required. Disadvantage of journaling filesystems
-is that they are slower than other filesystems.
-
-
-
-
-
-Some journaling filesystems:
-BeFS,
-HTFS,
-JFS,
-NSS,
-Spiralog filesystem,
-VxFS and
-XFS.

-
-GNU Parted is a program for creating, destroying, resizing, checking and
-copying partitions, and the filesystems on them.
-
-
-This is useful for creating space for new operating systems, reorganising
-disk usage, copying data between hard disks, and "disk imaging" - replicating
-installations over many computers.
-
-
-
-
-
-Parted has support for these operations:
-
-Filesystem detect create resize copy check
-ext2 * * *1 *2 *3
-fat * * *4 *4 *
-linux-swap * * * * *
-
-
-
-__NOTES:__
-
-
-(1) The start of the partition must stay fixed for ext2.
-
-
-
-
-
-(2) The partition you copy to must be bigger (or exactly the same size)
-as the partition you copy from.
-
-
-
-
-
-(3) Limited checking is done when the filesystem is opened. This is the
-only checking at the moment. All commands (including resize) will gracefully
-fail, leaving the filesystem in tact, if there are any errors in the file
-system (and the vast majority of errors in general).
-
-
-
-
-
-(4) The size of the new partition, after resizing or copying, is restricted
-by the cluster size for fat (mainly affects FAT16). This is worse than you
-think, because you don't get to choose your cluster size (it's a bug in
-Windows, but you want compatibility, right?).
-
-
-
-
-
-So, in practise, you can always shrink your partition (because Parted
-can shrink the cluster size), but you may not be able to grow the partition
-to the size you want. If you don't have any problems with using FAT32, you
-will always be able to grow the partition to the size you want.
-
-
-Summary: you can always shrink your partition. If you can't use
-FAT32 for some reason, you may not be able to grow your partition.

-
-
-!!3.1 VFAT: Long filenames
-
-
-
-Windows 95/98 and Windows NT/2000 store long filenames on FAT in special
-directory entries with set attributes __!ReadOnly__, __Hidden__,
-__System__ and __Volume__, so if you access FAT volume from DOS
-you don't see these "files". These special entries have this mad structure:
-
-
-
-
-byte sequence number for slot
-string(10) first 5 characters in name
-byte attribute byte
-byte always
-byte checksum for 8.3 alias
-string(12) 6 more characters in name
-word starting cluster number, 0 in long slots
-string(4) last 2 characters in name
-
-
-
-Problem occur when you delete or modify file with long name from system without
-VFAT support, because only DOS 8+3 entry will be deleted or modified. Scandisk
-from Windows 95/98 can repair this problem.
-

-!!3.2 UMSDOS: Linux LFN/attributes on FAT filesystem
-
-
-
-Linux has it's own FAT extensions which gives you long filenames, permissions
-and owners, links and special devices on FAT partition, called UMSDOS.
-Each directory contains file named
-__"--linux-.---"__. There are stored long names and other necessary
-fields. For more information see file __/usr/src/linux/Documentation/filesystems/umsdos.txt__. Author of Linux umsdos driver is Jacques Gelinas
-<
-jacques@solucorp.qc.ca>
-and it is currently maintained by Matija Nalis

-
-!!3.3 OS/2 Extended Attributes on FAT filesystems
-
-
-
-OS/2 Warp version 3,4 and 5 stores long filenames and extended attributes on FAT
-volume in files "\ea data. sf" and "\wp root. sf" (both files are in root
-directory of filesystem). AFAIK there is no known implementation of OS/2 EAs
-for any other OS. If you can supply any information about EA structure, don't
-hesitate to mail them to

-
-
-
-Star LFN is an emulator that allows programs, running under DOS 4.0 or
-above, to use the long filename functions present in Windows'95 DOS
-boxes. Currently, it can only read and write long filenames from and
-into a system+hidden file, which means you can't either read or write
-real Windows'95 long filenames. For more information see

-LFNDOS provides the Windows95 Long Filename (LFN) API to DOS programs.
-It uses the same format for storing the
-names on disk as Windows95 does, so you can view and use long filenames under
-both systems interchangeably. It runs as a memory-resident program, and while resident requires about 60k of conventional memory.
-
-
-
-
-
-Under Windows95, a DOS program can use long filenames by calling a set
-of interrupt functions, which Windows provides. For example, COMMAND.COM
-will allow long filenames when run as a DOS Prompt from Windows, but not
-if you restart in MS-DOS mode. Other programs such as EDIT.COM and all DJGPP
-programs use long filenames if available.

-!!6.1 Extended filesystem (ExtFS)
-
-
-
-This is old filesystem used in early Linux systems.
-
-
-
-
-
-
-
-!!6.2 Second Extended Filesystem (Ext2 FS)
-
-
-
-The Second Extended File System is probably the most widely
-used filesystem in the Linux community. It provides standard
-Unix file semantics and advanced features. Moreover, thanks to
-the optimizations included in the kernel code, it is robust and
-offers excellent performance.
-
-
-
-
-
-Since Ext2fs has been designed with evolution in mind, it
-contains hooks that can be used to add new features. Some
-people are working on extensions to the current filesystem:
-access control lists conforming to the Posix semantics, undelete,
-and on-the-fly file compression.
-
-
-
-
-
-Ext2fs was first developed and integrated in the Linux
-kernel and is now actively being ported to other operating
-systems. An Ext2fs server running on top of the GNU Hurd has
-been implemented. People are also working on an Ext2fs port in
-the LITES server, running on top of the Mach microkernel
-and in the VSTa operating system. Last, but not least, Ext2fs is an
-important part of the Masix operating system, currently under
-development by one of the authors.
-
-
-
-
-!Motivations
-
-
-The Second Extended File System has been designed and
-implemented to fix some problems present in the first Extended
-File System. Our goal was to provide a powerful filesystem,
-which implements Unix file semantics and offers advanced
-features.
-
-
-
-
-
-Of course, we wanted to Ext2fs to have excellent
-performance. We also wanted to provide a very robust
-filesystem in order to reduce the risk of data loss in
-intensive use. Last, but not least, Ext2fs had to include
-provision for extensions to allow users to benefit from new
-features without reformatting their filesystem.
-
-
-
-
-
-
-
-!``Standard'' Ext2fs features
-
-
-The Ext2fs supports standard Unix file types: regular files,
-directories, device special files and symbolic links.
-
-
-
-
-
-Ext2fs is able to manage filesystems created on really big
-partitions. While the original kernel code restricted the
-maximal filesystem size to 2 GB, recent work in the VFS layer
-have raised this limit to 4 TB. Thus, it is now possible to use
-big disks without the need of creating many partitions.
-
-
-
-
-
-Ext2fs provides long file names. It uses variable length
-directory entries. The maximal file name size is 255
-characters. This limit could be extended to 1012 if needed.
-
-
-
-
-
-Ext2fs reserves some blocks for the super user
-(root). Normally, 5% of the blocks are reserved. This
-allows the administrator to recover easily from situations
-where user processes fill up filesystems.
-
-
-
-
-
-
-
-!``Advanced'' Ext2fs features
-
-
-In addition to the standard Unix features, Ext2fs supports
-some extensions which are not usually present in Unix
-filesystems.
-
-
-
-
-
-File attributes allow the users to modify the kernel
-behavior when acting on a set of files. One can set attributes
-on a file or on a directory. In the later case, new files
-created in the directory inherit these attributes.
-
-
-
-
-
-BSD or System V Release 4 semantics can be selected at mount
-time. A mount option allows the administrator to choose the
-file creation semantics. On a filesystem mounted with BSD
-semantics, files are created with the same group id as their
-parent directory. System V semantics are a bit more complex: if
-a directory has the setgid bit set, new files inherit the group
-id of the directory and subdirectories inherit the group id and
-the setgid bit; in the other case, files and subdirectories are
-created with the primary group id of the calling process.
-
-
-
-
-
-BSD-like synchronous updates can be used in Ext2fs. A mount
-option allows the administrator to request that metadata
-(inodes, bitmap blocks, indirect blocks and directory blocks)
-be written synchronously on the disk when they are modified.
-This can be useful to maintain a strict metadata consistency
-but this leads to poor performances. Actually, this feature is
-not normally used, since in addition to the performance loss
-associated with using synchronous updates of the metadata, it
-can cause corruption in the user data which will not be flagged
-by the filesystem checker.
-
-
-
-
-
-Ext2fs allows the administrator to choose the logical block
-size when creating the filesystem. Block sizes can typically be
-1024, 2048 and 4096 bytes. Using big block sizes can speed up
-I/O since fewer I/O requests, and thus fewer disk head seeks,
-need to be done to access a file. On the other hand, big blocks
-waste more disk space: on the average, the last block allocated
-to a file is only half full, so as blocks get bigger, more
-space is wasted in the last block of each file. In addition,
-most of the advantages of larger block sizes are obtained by
-Ext2 filesystem's preallocation techniques.
-
-
-
-
-
-Ext2fs implements fast symbolic links. A fast symbolic link
-does not use any data block on the filesystem. The target name
-is not stored in a data block but in the inode itself. This
-policy can save some disk space (no data block needs to be
-allocated) and speeds up link operations (there is no need to
-read a data block when accessing such a link). Of course, the
-space available in the inode is limited so not every link can
-be implemented as a fast symbolic link. The maximal size of the
-target name in a fast symbolic link is 60 characters. We plan
-to extend this scheme to small files in the near future.
-
-
-
-
-
-Ext2fs keeps track of the filesystem state. A special field
-in the superblock is used by the kernel code to indicate the
-status of the file system. When a filesystem is mounted in
-read/write mode, its state is set to ``Not Clean''. When it is
-unmounted or remounted in read-only mode, its state is reset to
-``Clean''. At boot time, the filesystem checker uses this
-information to decide if a filesystem must be checked. The
-kernel code also records errors in this field. When an
-inconsistency is detected by the kernel code, the filesystem is
-marked as ``Erroneous''. The filesystem checker tests this to
-force the check of the filesystem regardless of its apparently
-clean state.
-
-
-
-
-
-Always skipping filesystem checks may sometimes be
-dangerous, so Ext2fs provides two ways to force checks at
-regular intervals. A mount counter is maintained in the
-superblock. Each time the filesystem is mounted in read/write
-mode, this counter is incremented. When it reaches a maximal
-value (also recorded in the superblock), the filesystem checker
-forces the check even if the filesystem is ``Clean''. A last
-check time and a maximal check interval are also maintained in
-the superblock. These two fields allow the administrator to
-request periodical checks. When the maximal check interval has
-been reached, the checker ignores the filesystem state and
-forces a filesystem check.
-
-
-
-
-
-An attribute allows the users to request secure deletion on
-files. When such a file is deleted, random data is written in
-the disk blocks previously allocated to the file. This prevents
-malicious people from gaining access to the previous content of
-the file by using a disk editor.
-
-
-
-
-
-Last, new types of files inspired from the 4.4 BSD
-filesystem have recently been added to Ext2fs. Immutable files
-can only be read: nobody can write or delete them. This can be
-used to protect sensitive configuration files. Append-only
-files can be opened in write mode but data is always appended
-at the end of the file. Like immutable files, they cannot be
-deleted or renamed. This is especially useful for log files
-which can only grow.
-
-
-
-
-
-
-
-!Physical Structure
-
-
-
-
-
-The physical structure of Ext2 filesystems has been strongly
-influenced by the layout of the BSD filesystem. A
-filesystem is made up of block groups. Block groups are
-analogous to BSD FFS's cylinder groups. However, block groups
-are not tied to the physical layout of the blocks on the disk,
-since modern drives tend to be optimized for sequential access
-and hide their physical geometry to the operating system.
-
-,---------+---------+---------+---------+---------,
-| Boot | Block | Block | ... | Block |
-| sector | group 1 | group 2 | | group n |
-`---------+---------+---------+---------+---------'
-
-
-
-
-
-
-Each block group contains a redundant copy of crucial filesystem
-control informations (superblock and the filesystem descriptors) and
-also contains a part of the filesystem (a block bitmap, an inode
-bitmap, a piece of the inode table, and data blocks). The structure of
-a block group is represented in this table:
-
-,---------+---------+---------+---------+---------+---------,
-| Super | FS | Block | Inode | Inode | Data |
-| block | desc. | bitmap | bitmap | table | blocks |
-`---------+---------+---------+---------+---------+---------'
-
-
-
-
-
-
-Using block groups is a big win in terms of reliability:
-since the control structures are replicated in each block
-group, it is easy to recover from a filesystem where the
-superblock has been corrupted. This structure also helps to get
-good performances: by reducing the distance between the inode
-table and the data blocks, it is possible to reduce the disk
-head seeks during I/O on files.
-
-
-
-
-
-In Ext2fs, directories are managed as linked lists of
-variable length entries. Each entry contains the inode number,
-the entry length, the file name and its length. By using
-variable length entries, it is possible to implement long file
-names without wasting disk space in directories.
-
-
-
-
-
-
-
-
-
-
-!Performance optimizations
-
-
-In Linux, the Ext2fs kernel code contains many performance
-optimizations, which tend to improve I/O speed when reading and
-writing files.
-
-
-
-
-
-Ext2fs takes advantage of the buffer cache management by
-performing readaheads: when a block has to be read, the kernel
-code requests the I/O on several contiguous blocks. This way,
-it tries to ensure that the next block to read will already be
-loaded into the buffer cache. Readaheads are normally performed
-during sequential reads on files and Ext2fs extends them to
-directory reads, either explicit reads (readdir(2)
-calls) or implicit ones (namei kernel directory
-lookup).
-
-
-
-
-
-Ext2fs also contains many allocation optimizations. Block
-groups are used to cluster together related inodes and data:
-the kernel code always tries to allocate data blocks for a file
-in the same group as its inode. This is intended to reduce the
-disk head seeks made when the kernel reads an inode and its
-data blocks.
-
-
-
-
-
-When writing data to a file, Ext2fs preallocates up to 8
-adjacent blocks when allocating a new block. Preallocation hit
-rates are around 75% even on very full filesystems. This
-preallocation achieves good write performances under heavy
-load. It also allows contiguous blocks to be allocated to
-files, thus it speeds up the future sequential reads.
-
-
-
-
-
-These two allocation optimizations produce a very good locality of:
-
-
-* related files through block groups
-*
-
-* related blocks through the 8 bits clustering of block allocations.
-*

-This is a full working Ext2 filesystem driver for FreeMiNT.
-It can read and write the actual ext2 version as implemented in Linux
-for example. The partition size is not limited and the logical sector
-size can be 1024, 2048 or 4096 bytes. The only restriction is that the
-physical sector size is smaller or equal to the logical sector size.
-The blocksize can be configured if you initialize the partition with

-!! 7. Macintosh Hierarchical Filesystem - HFS
-
-
-All Macintosh storage devices except floppy disks are partitioned into
-one or more volumes. Volumes can contain four kinds of items: files,
-directories, directory threads and file threads. Each item is described
-by a catalog record which is analogous to a Unix inode. Catalog records
-are organized in the on-disk catalog B-Tree. Directory contents are
-derived from searching the catalog B-Tree. Only a file can occupy space
-outside of its catalog record.
-
-
-
-
-
-A Macintosh "file" contains two components,
-or forks. The resource fork is an indexed file containing code
-segments, menu items, dialog boxes, etc. The data fork has the "stream of
-bytes" semantics of a Unix file contents. Each fork is comprised of one
-or more extents or contiguous runs of blocks. An extent descriptor encodes
-an extent's starting block and length into a 32bit quantity. The first
-extent record (three extent descriptors) of each fork is a part of the
-file's catalog record. Any further extent records are kept in the
-extents overflow B-Tree.
-
-
-
-
-
-In addition to file and B-Tree extents a volume also contains two boot
-blocks, a volume information block, and a free space bitmap. There is
-a remarkable amount of redundancy in the on diskdata structures which
-improves crash recovery. While not strictly a part of the filesystem,
-it should be noted that several catalog record fields are reserved
-for the exclusive use of Finder, a program which handles user access
-to the filesystem and automatically maintains associations between
-applications and data files. Thus, HFS must also maintain this Finder
-info.
-
-
-
-
-
-Every file and directory on an HFS volume has an identification number,
-similar to an inode number in the Unix filesystem. However, a file or
-directory is named by its parent's identification number and the file
-or directory's file name, which is a 32 character string that can
-contain nulls. This combination is the search key to the volume's
-catalog B-Tree. The catalog B-Tree differs from a traditional B-Tree
-structure in that all the nodes at each level of the B-Tree are linked
-together to form a doubly linked list and all of the records are in
-the leaf nodes. These variations permit accessing many items in the
-same directory by traversing the leaves using the linked list. Strictly
-speaking, the HFS B-Trees are a variant of B+-Trees although Apple's
-technical documentation calls them B*-Trees.
-
-
-
-
-
-Each directory, including the root directory, contains its directory
-thread, which has the empty filename. The directory thread record
-contains the name of the directory and the id of the parent of the directory.
-Similarly, filethreads contain the name of a file and the id of the
-directory they are in. While every directory must contain a directory
-thread, file threads are very uncommon. In fact, both are examples of
-HFS redundancy - for undamaged trees, threads are not strictly necessary.
-Both file and directory records contain 32 bytes of information used by
-Finder. The first three extent descriptors for the catalog B-Tree are kept
-in the volume information block. If the catalog B-Tree file grows beyond
-three extents, the remaining extent descriptors are kept in the extents
-overfow.

-This is a Macintosh file system library which is portable to a
-variety of operating systems and platforms. It presents a programming
-interface sufficient for creating a user level API as well as file system
-drivers for operating systems that support them. Authors implemented
-and tested such a user level API and utility programs based on it
-as well as an experimental Unix Virtual File System.
-They also describe the Macintosh Hierarchical File System and their
-implementation and note that
-the design is not well suited to reentrancy and that its complex
-data structures can lead to slow
-implementations in multiprogrammed environments. Performance
-measurements show that
-our implementation is faster than the native Macintosh
-implementation at creating, deleting,
-reading and writing files with small request sizes, but slower than the Berkeley Fast File
-System (FFS.) However, the native Macintosh implementation can
-perform large read and write operations faster that either our
-implementation or FFS.

-DTFS supports LZW and no-compression but you can add your own algorithms. Some
-space is saved by not pre-allocating inodes. Any disk block is fair game

-!! 9.7 EFS - Enhanced filesystem (Linux)
-
-
-
-The Enhanced Filing system project aims to create a new
-filing system for Linux and eventually other OSs which will allow the administrator
-to define mountable "file systems" on a set of block devices (either hard
-drives or partitions). The aim is to allow file systems to be added or
-removed from the partition set while the system is running and partitions
-may be added to a set (or removed if the remaining partitions have enough
-space to contain all the data) while the system is running.The two main aims are to allow a number of mountable
-file systems to share the same pool of storage space (IE have the user
-home dirs on the same drive as the news spool but have separate accounting
-for them), and to allow the easy addition of more hard drives to allow
-more space.
-
-
-
-
-
-Some other features that authors want to implement are
-logging/journaling, support
-for as many OSs as possible (although all work will be initially done on
-Linux), and quotas in the FS so we don't need to waste ages running a silly
-quotacheck program at boot - the logging should avoid quotacheck the same
-way it avoids fsck! They want to be able to boot a system with 10gig of news
-spread over 4 hard drives with full quotas AFTER a power failure with less
-than 20 seconds for mounting file systems!

-!! 9.8 EFS - Extent filesystem (IRIX)
-
-
-
-The Extent File System (efs) is Silicon Graphics' early block-device
-filesystem, widely used on pre-6.0 versions of IRIX. Since 6., xfs
-has been bundled with IRIX and users are being encouraged to migrate
-to xfs filesystems. IRIX support for efs will be read-only in versions
-of IRIX beyond 6.5, however efs is still very much in use on SGI
-software distribution CDs.
-
-
-
-
-
-There are two kernel modules for linux to access EFS filesystem.

-The efs kernel module is an implementation of
-the extent file system for linux 2.2 kernels. An efs implementation
-(efsmod-.6.tar.gz) was originally written for 1.x kernels by
-Christian Vogelgsang.
-In this implementation the code has undergone a complete rewrite
-and is also endian-clean. To use the efs module, you will need
-to have at least a 2.2 kernel. To mount IRIX CDs, your CD-ROM
-will need to be able to cope with 512-byte blocks.
-This version of efs contains support for hard-disk partitions, and also
-contains a kernel patch to allow you to install the efs code into your
-linux kernel tree. Handling of large files has also been vastly improved.

-
-
-
-This is a UNIX(tm) operating system style file
-system designed for the RS/6000 SP(tm) server. It allows
-applications on multiple nodes to share file data. GPFS
-supports very large file systems and stripes data across
-multiple disks for higher performance. GPFS is based on a
-shared disk model which provides lower overhead access to
-disks not directly attached to the application nodes and
-uses a distributed locking protocol to provide full data
-coherence for access from any node. It offers many of the
-standard AIX(tm) file system interfaces allowing most
-applications to execute without modification or
-recompiling. These capabilities are available while
-allowing high speed access to the same data from all
-nodes of the SP system, and providing full data coherence
-for operations occurring on the various nodes. GPFS
-attempts to continue operation across various node and
-component failures assuming that sufficient resources
-exist to continue.

-Reiserfs is a file system using a variant on classical balanced tree

-allocation based file system running under the same operating system
-and employing the same buffering code suggest that these algorithms
-are more effective for large files and small files not near node size
-in time performance, become less effective in time performance and
-more significantly effective in space performance as one approaches
-files close to the node size, and become markedly more effective in
-both space and time as file size decreases substantially below node
-size (4k), reaching order of magnitude advantages for file sizes of
-100bytes. The improvement in small file space and time performance
-suggests that we may now revisit a common OS design assumption that
-one should aggregate small objects using layers above the file system
-layer.

-!! 9.32 XFS - Extended filesystem (IRIX)
-
-
-
-
-
-
-
-
-
-XFS(tm) is the next-generation file system for
-Silicon Graphics
[[TM
] systems, from desktop workstations to supercomputers.
-XFS provides full 64-bit file capabilities that scale easily to handle
-extremely large files and file systems that grow to 1 terabyte. The XFS file
-system integrates volume management, guaranteed rate I/O, and
-journaling
-technology for fast, reliable recovery. File systems can be backed up while
-still in use, significantly reducing administrative overhead.
-
-
-
-
-
-XFS is designed for a very high performance; sustained throughput in excess
-of 300MB per second has been demonstrated on CHALLENGE systems.
-The XFS file system scales in performance to match the CHALLENGE MP
-architecture. Traditional files, directories, and file systems have reduced
-performance as they grow in size. With the XFS file system, there is no
-performance penalty. For example, XFS directories have been tested with up to
-32 million files in a single directory.
-
-
-
-
-
-XFS is a journalled file system. It logs changes to the inodes,
-directories and bitmaps to the disk before the original entries are updated.
-Should the system crash before the updates are done they can be recreated
-using the log and updated as intended.
-
-
-
-
-
-XFS uses a space manager to allocate disk space for the file system and
-control the inodes. It uses a namespace manager to control allocation of
-directory files. These managers use B-tree indexing to store file location
-information, significantly decreasing the access time needed to retrieve file
-information.
-
-
-
-
-
-Inodes are created as needed and are not restricted to a particular area on a
-disk partition. XFS tries to position the inodes close to the files and
-directories they reference. Very small files, such as symbolic links and
-some directories, are stored as part of the inode, to increase performance
-and save space. Large directories use B-tree indexing within the directory
-file to speed up directory searches, additions and deletions.

-
-There is a brief list of some which I know:
-

-
-
-
-
-
-* The AFS FAQ is at
-http://www.angelfire.com/hi/plutonic/afs-faq.html.
-*
-
-* Commercial clients and servers for almost all platforms (except win98)
-are available from IBM. See
-http://www.transarc.com/Product/EFS/AFS/index.html
-*
-
-* A free client for Unix is available from the Arla Team at
-http://www.stacken.kth.se/projekt/arla/.
-*
-
-* A free Server is also in preparation, but not in production yet.

-Intermezzo is a distributed file system for Linux. It was inspired
-from coda but uses the disk file system as a persistent cache.
-Intermezzo supports disconnected operation but does not yet
-implement an identification system.

-CFS pushes encryption services into the Unix(tm) file system. It
-supports secure storage at the system level through a standard Unix
-file system interface to encrypted files. Users associate a
-cryptographic key with the directories they wish to protect. Files in
-these directories (as well as their pathname components) are
-transparently encrypted and decrypted with the specified key without
-further user intervention; cleartext is never stored on a disk or sent
-to a remote file server. CFS employs a novel combination of DES
-stream and codebook cipher modes to provide high security with good
-performance on a modern workstation. CFS can use any available file
-system for its underlying storage without modification, including
-remote file servers such as NFS. System management functions, such as
-file backup, work in a normal manner and without knowledge of the key.

-The main difference between TCFS and CFS is the trasparency to
-user obtained by using TCFS. As a matter of fact, CFS works in
-user space while TCFS works in the kernel space thus resulting
-in improved performances and security.
-The dynamic encryption module feature of TCFS allows a user
-to specify the encryption engine of his/her choiche to be used
-by TCFS.
-Currently available only for Linux, TCFS will be relased soon
-also for NetBSD, and will support in a near future also other
-FS then NFS.

-fspatch is a kernel patch which introduces module support for the
-steganographic file system (formerly known as vs3fs, an experimental
-type of filesytem that not only encrypts all information on the disk,
-but also tries to hide that information in such a way that it cannot be
-proven to even exist on the disk. This enables you to keep sensitive
-information on a disk, while not be prone to being forced to reveal that
-information. Even under extreme circumstances, fake documents could be
-stored on other parts of the disk, for which a pasword may be revealed.
-It should not be possible to find out whether any other information is
-stored on the disk.
