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 a 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
|
Set the new size in bytes. |
|
Set the journal device name. |
|
Force, do not perform checks. |
|
Do not print anything but error messages. |
|
Turn on extra progress status messages
(default). |
RETURN VALUES
|
-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 |
