    NAME

    resize_reiserfs - resizer tool for the ReiserFS filesystem
     
    

    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 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 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 on /mnt. For shrinking the device we need to unmount it first, then run resize_reiserfs with a size parameter (in this case -1Gb):

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