resize_reiserfs


SYNOPSIS
       resize_reiserfs [ -s [+|-]size[K|M|G] ] [ -j dev ] [ -fqv ] device

DESCRIPTION
       The resize_reiserfs tool resizes an unmounted reiserfs file system.  It
       enlarges or shrinks an reiserfs file system located on a device so that
       it  will have size bytes or size=old_size +(-) size bytes if the + or -
       prefix is used.  If the -s option is not specified, the filesystem will
       be  resized  to fill the given device.  The size parameter may have one
       of the optional modifiers K, M, G, which means the  size  parameter  is
       given in kilo-, mega-, gigabytes respectively.

       The resize_reiserfs program does not manipulate the size of the device.
       If you wish to enlarge a filesystem, you must make sure you expand  the
       underlying  device  first.  This can be done using cfdisk(8) for parti-
       tions, by deleting the partition and recreating it with a  larger  size
       (assuming  there  is free space after the partition in question).  Make
       sure you re-create it with the same starting disk cylinder  as  before!
       Otherwise,  the  resize  operation will certainly not work, and you may
       lose your entire filesystem.

       The resize_reiserfs program allows to grow a reiserfs on-line if  there
       is a free space on block device.


       If  you  wish to shrink a reiserfs partition, first use resize_reiserfs
       to shrink the file system. You may then use  cfdisk(8)  to  shrink  the
       device.  When  shrinking  the  size of the device, make sure you do not
       make it smaller than the reduced size of the reiserfs filesystem.


OPTIONS
       -s [+|-]size
              Set the new size in bytes.

       -j dev Set the journal device name.

       -f     Force, do not perform checks.

       -q     Do not print anything but error messages.

       -v     Turn on extra progress status messages (default).


RETURN VALUES
       0    Resizing successful.

       -1   Resizing not successful.


EXAMPLES
       The following example shows how to test resize_reiserfs.   Suppose  2Gb
       reiserfs  filesystem  is created on the device /dev/hda8 and is mounted
       Zarochentcev <zam@namesys.com>.

BUGS
       Please   report   bugs   to   the   ReiserFS   developers    <reiserfs-
       dev@namesys.com>, providing as much information as possible--your hard-
       ware, kernel, patches, settings, all printed messages; check the syslog
       file for any related information.
