resize_reiserfs - resizer tool for the ReiserFS filesystem
] [ -j dev ] [ -fqv
tool resizes an unmounted reiserfs file system. It
enlarges or shrinks an reiserfs file system located on a device
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
may have one of the optional modifiers K
means the size
parameter is given in kilo-, mega-, gigabytes
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)
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
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
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.
- -s [+|-]size
- Set the new size in bytes.
- -j dev
- Set the journal device name.
- Force, do not perform checks.
- Do not print anything but error messages.
- Turn on extra progress status messages (default).
0 Resizing successful.
- -1 Resizing not successful.
The following example shows how to test resize_reiserfs.
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
with a size parameter (in this case -1Gb):
resize_reiserfs -s -1G /dev/hda8
mount /dev/hda8 /mnt
