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

879 performed by the driver as well as additional debugging messages to
880 be written to the system log. Note that debugging messages are
881 disabled by default. To enable them, supply the option debug_msgs=1
882 at the kernel command line when booting the kernel or as an option
883 to insmod when loading the ntfs module. Once the driver is active,
884 you can enable debugging messages by doing (as root):
885 echo 1 > /proc/sys/fs/ntfs-debug
886 Replacing the "1" with "0" would disable debug messages.

899 This enables the partial, but safe, write support in the NTFS driver.

901 The only supported operation is overwriting existing files, without
902 changing the file length. No file or directory creation, deletion or
903 renaming is possible. Note only non-resident files can be written to
904 so you may find that some very small files (<500 bytes or so) cannot
905 be written to.
906
907 While we cannot guarantee that it will not damage any data, we have
908 so far not received a single report where the driver would have
909 damaged someones data so we assume it is perfectly safe to use.
910
911 Note: While write support is safe in this version (a rewrite from
912 scratch of the NTFS support), it should be noted that the old NTFS
913 write support, included in Linux 2.5.10 and before (since 1997),
914 is not safe.

1971 Extended attributes are name:value pairs associated with inodes by
1972 the kernel or by users (see the attr(5) manual page, or visit
1973 <http://acl.bestbits.at/> for details). CIFS maps the name of
1974 extended attributes beginning with the user namespace prefix
1975 to SMB/CIFS EAs. EAs are stored on Windows servers without the
1976 user namespace prefix, but their names are seen by Linux cifs clients
1977 prefaced by the user namespace prefix. The system namespace
1978 (used by some filesystems to store ACLs) is not supported at
1979 this time.

2033 NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
2034 used by Novell NetWare clients to talk to file servers. It is to
2035 IPX what NFS is to TCP/IP, if that helps. Saying Y here allows you
2036 to mount NetWare file server volumes and to access them just like
2037 any other Unix directory. For details, please read the file
2038 <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
2039 the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.

2056 Coda is an advanced network file system, similar to NFS in that it
2057 enables you to mount file systems of a remote server and access them
2058 with regular Unix commands as if they were sitting on your hard
2059 disk. Coda has several advantages over NFS: support for
2060 disconnected operation (e.g. for laptops), read/write server
2061 replication, security model for authentication and encryption,
2062 persistent client caches and write back caching.
2063
2064 If you say Y here, your Linux box will be able to act as a Coda
2065 *client*. You will need user level code as well, both for the
2066 client and server. Servers are currently user level, i.e. they need
2067 no kernel support. Please read
