       resize_reiserfs - resizer tool for the ReiserFS filesystem


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


       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 partitions, 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


       -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).


       0    Resizing successful.

       -1   Resizing not successful.


       The  following example shows how to test resize_reiserfs.  Suppose 2Gb reiserfs filesystem
       is created on the device /dev/hda8 and is mounted on /mnt.  For shrinking  the  device  we
       need  to  unmount  it first, then run resize_reiserfs with a size  parameter (in this case

            umount /mnt
            resize_reiserfs -s -1G /dev/hda8
            mount /dev/hda8 /mnt
            df /mnt
