        help

          This is the journalling 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 journalling 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 ).

          To compile this file system support as a module, choose M here: the

          Ext4dev is a predecessor filesystem of the next generation

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

          renamed ext4 fs later, once ext4dev is mature and stabilized.

          Unlike the change from ext2 filesystem to ext3 filesystem,

          the on-disk format of ext4dev is not the same as ext3 any more:

          it is based on extent maps and it supports 48-bit physical block

          numbers. These combined on-disk format changes will allow

          ext4dev/ext4 to handle more than 16 TB filesystem volumes --

          a hard limit that ext3 cannot overcome without changing the

          on-disk format.

          Other than extent maps and 48-bit block numbers, ext4dev also is

          likely to have other new features such as persistent preallocation,

          high resolution time stamps, and larger file support etc.  These

          features will be added to ext4dev gradually.

          In general, ReiserFS is as fast as ext2, but is very efficient with

          large directories and small files.  Additional patches are needed

          for NFS and quotas, please see  for links.

          It is more easily extended to have features currently found in

          database and keyword search systems than block allocation based file

          systems are.  The next version will be so extended, and will support

          This FAT support is not a file system in itself, it only provides

          Replacing the "1" with "0" would disable debug messages.

          If you leave debugging messages disabled, this results in little

          renaming is possible.  Note only non-resident files can be written to

          so you may find that some very small files (<500 bytes or so) cannot

          be written to.

          While we cannot guarantee that it will not damage any data, we have

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

          damaged someones data so we assume it is perfectly safe to use.

          Note:  While write support is safe in this version (a rewrite from

          scratch of the NTFS support), it should be noted that the old NTFS

          write support, included in Linux 2.5.10 and before (since 1997),

          is not safe.
