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
95 e2fsprogs version 1.20 or later in order to create ext3 journals

Mingming Cao02ea2102006-10-11 01:20:56 -0700144 Ext4dev is a predecessor filesystem of the next generation

Mingming Caodab291a2006-10-11 01:21:01 -0700148 Unlike the change from ext2 filesystem to ext3 filesystem,
149 the on-disk format of ext4dev is not the same as ext3 any more:

Mingming Caodab291a2006-10-11 01:21:01 -0700151 numbers. These combined on-disk format changes will allow
Mingming Cao02ea2102006-10-11 01:20:56 -0700152 ext4dev/ext4 to handle more than 16 TB filesystem volumes --
153 a hard limit that ext3 cannot overcome without changing the

1794 access them just like any other Unix directory. Currently, this
1795 works only if the Windows machines use TCP/IP as the underlying
1796 transport protocol, and not NetBEUI. For details, read

1798 available from <http://www.tldp.org/docs.html#howto>.

1801 files and printing services available to Windows clients (which need
1802 to have a TCP/IP stack), you don't need to say Y here; you can use
1803 the program SAMBA (available from <ftp://ftp.samba.org/pub/samba/>)
