Matt LaPlantecc2e2762006-10-03 22:22:29 +020075 This is the journalling version of the Second extended file system
Linus Torvalds1da177e2005-04-16 15:20:36 -070076 (often called ext3), the de facto standard Linux file system
77 (method to organize files on a storage device) for hard disks.
78
Matt LaPlantecc2e2762006-10-03 22:22:29 +020079 The journalling code included in this driver means you do not have
Linus Torvalds1da177e2005-04-16 15:20:36 -070080 to run e2fsck (file system checker) on your file systems after a
81 crash. The journal keeps track of any changes that were being made
82 at the time the system crashed, and can ensure that your file system
83 is consistent without the need for a lengthy check.
84
85 Other than adding the journal to the file system, the on-disk format
86 of ext3 is identical to ext2. It is possible to freely switch
87 between using the ext3 driver and the ext2 driver, as long as the
88 file system has been cleanly unmounted, or e2fsck is run on the file
89 system.
90
91 To add a journal on an existing ext2 file system or change the
92 behavior of ext3 file systems, you can use the tune2fs utility ("man
93 tune2fs"). To modify attributes of files and directories on ext3
94 file systems, use chattr ("man chattr"). You need to be using

146 extended fs ext4, based on ext3 filesystem code. It will be

Mingming Caodab291a2006-10-11 01:21:01 -0700149 Unlike the change from ext2 filesystem to ext3 filesystem,

Mingming Cao02ea2102006-10-11 01:20:56 -0700153 ext4dev/ext4 to handle more than 16 TB filesystem volumes --
154 a hard limit that ext3 cannot overcome without changing the

856 be written to the system log. Note that debugging messages are
857 disabled by default. To enable them, supply the option debug_msgs=1
858 at the kernel command line when booting the kernel or as an option
859 to insmod when loading the ntfs module. Once the driver is active,
860 you can enable debugging messages by doing (as root):
861 echo 1 > /proc/sys/fs/ntfs-debug
862 Replacing the "1" with "0" would disable debug messages.
863
864 If you leave debugging messages disabled, this results in little
865 overhead, but enabling debug messages results in very significant
866 slowdown of the system.

874 help
875 This enables the partial, but safe, write support in the NTFS driver.
876
877 The only supported operation is overwriting existing files, without
878 changing the file length. No file or directory creation, deletion or
879 renaming is possible. Note only non-resident files can be written to
880 so you may find that some very small files (<500 bytes or so) cannot
881 be written to.
882
883 While we cannot guarantee that it will not damage any data, we have
884 so far not received a single report where the driver would have
885 damaged someones data so we assume it is perfectly safe to use.
886
887 Note: While write support is safe in this version (a rewrite from
888 scratch of the NTFS support), it should be noted that the old NTFS
889 write support, included in Linux 2.5.10 and before (since 1997),
890 is not safe.

892 This is currently useful with TopologiLinux. TopologiLinux is run
893 on top of any DOS/Microsoft Windows system without partitioning your
894 hard disk. Unlike other Linux distributions TopologiLinux does not
895 need its own partition. For more information see

911 The sysfs filesystem is a virtual filesystem that the kernel uses to
912 export internal kernel objects, their attributes, and their
913 relationships to one another.
914
915 Users can use sysfs to ascertain useful information about the running
916 kernel, such as the devices the kernel has discovered on each bus and
917 which driver each is bound to. sysfs can also be used to tune devices
918 and other kernel subsystems.
919
920 Some system agents rely on the information in sysfs to operate.
921 /sbin/hotplug uses device and object attributes in sysfs to assist in

1965 Enabling this option adds a few more debugging routines
1966 to the cifs code which slightly increases the size of
1967 the cifs module and can cause additional logging of debug

2010 NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
2011 used by Novell NetWare clients to talk to file servers. It is to
2012 IPX what NFS is to TCP/IP, if that helps. Saying Y here allows you
2013 to mount NetWare file server volumes and to access them just like
2014 any other Unix directory. For details, please read the file
2015 <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
2016 the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.

2033 Coda is an advanced network file system, similar to NFS in that it
2034 enables you to mount file systems of a remote server and access them
2035 with regular Unix commands as if they were sitting on your hard
2036 disk. Coda has several advantages over NFS: support for
2037 disconnected operation (e.g. for laptops), read/write server
2038 replication, security model for authentication and encryption,
2039 persistent client caches and write back caching.
2040
2041 If you say Y here, your Linux box will be able to act as a Coda
2042 *client*. You will need user level code as well, both for the
2043 client and server. Servers are currently user level, i.e. they need
2044 no kernel support. Please read

2046 home page <http://www.coda.cs.cmu.edu/>.
