This is the journaling version of the Second extended file system
|
|
(often called ext3), the de facto standard Linux file system
|
|
(method to organize files on a storage device) for hard disks.
|
|
|
|
The journaling code included in this driver means you do not have
|
|
to run e2fsck (file system checker) on your file systems after a
|
|
crash. The journal keeps track of any changes that were being made
|
|
at the time the system crashed, and can ensure that your file system
|
|
is consistent without the need for a lengthy check.
|
|
|
|
Other than adding the journal to the file system, the on-disk format
|
|
of ext3 is identical to ext2. It is possible to freely switch
|
|
between using the ext3 driver and the ext2 driver, as long as the
|
|
file system has been cleanly unmounted, or e2fsck is run on the file
|
|
system.
|
|
|
|
To add a journal on an existing ext2 file system or change the
|
|
behavior of ext3 file systems, you can use the tune2fs utility ("man
|
|
tune2fs"). To modify attributes of files and directories on ext3
|
|
file systems, use chattr ("man chattr"). You need to be using
|
|
e2fsprogs version 1.20 or later in order to create ext3 journals
|

(available at <http://sourceforge.net/projects/e2fsprogs/>).

so far not received a single report where the driver would have

SMB (Server Message Block) is the protocol Windows for Workgroups
|
|
(WfW), Windows 95/98, Windows NT and OS/2 Lan Manager use to share
|
|
files and printers over local networks. Saying Y here allows you to
|
|
mount their file systems (often called "shares" in this context) and
|
|
access them just like any other Unix directory. Currently, this
|
|
works only if the Windows machines use TCP/IP as the underlying
|
|
transport protocol, and not NetBEUI. For details, read
|
|
<file:Documentation/filesystems/smbfs.txt> and the SMB-HOWTO,
|
|
available from <http://www.tldp.org/docs.html#howto>.
|
|
|
|
Note: if you just want your box to act as an SMB *server* and make
|
|
files and printing services available to Windows clients (which need
|
|
to have a TCP/IP stack), you don't need to say Y here; you can use
|
|
the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>)
|
|
for that.

This is the client VFS module for the Common Internet File System
|
|
(CIFS) protocol which is the successor to the Server Message Block
|
|
(SMB) protocol, the native file sharing mechanism for most early
|
|
PC operating systems. The CIFS protocol is fully supported by
|
|
file servers such as Windows 2000 (including Windows 2003, NT 4
|
|
and Windows XP) as well by Samba (which provides excellent CIFS
|
|
server support for Linux and many other operating systems). Limited
|
|
support for Windows ME and similar servers is provided as well.
|
|
You must use the smbfs client filesystem to access older SMB servers
|
|
such as OS/2 and DOS.
|
|
|
|
The intent of the cifs module is to provide an advanced
|
|
network file system client for mounting to CIFS compliant servers,
|
|
including support for dfs (hierarchical name space), secure per-user
|
|
session establishment, safe distributed caching (oplock), optional
|
|
packet signing, Unicode and other internationalization improvements,
|
|
and optional Winbind (nsswitch) integration. You do not need to enable
|
|
cifs if running only a (Samba) server. It is possible to enable both
|
|
smbfs and cifs (e.g. if you are using CIFS for accessing Windows 2003
|
|
and Samba 3 servers, and smbfs for accessing old servers). If you need

Extended attributes are name:value pairs associated with inodes by

extended attributes beginning with the user namespace prefix

to SMB/CIFS EAs. EAs are stored on Windows servers without the

user namespace prefix, but their names are seen by Linux cifs clients

prefaced by the user namespace prefix. The system namespace

Coda is an advanced network file system, similar to NFS in that it

enables you to mount file systems of a remote server and access them

with regular Unix commands as if they were sitting on your hard

replication, security model for authentication and encryption,

persistent client caches and write back caching.

If you say Y here, your Linux box will be able to act as a Coda
