NAME¶
nilfs-resize - resize NILFS file system volume size
SYNOPSIS¶
nilfs-resize [
options]
device [
size]
DESCRIPTION¶
The
nilfs-resize program will resize NILFS2 file systems. It can be used
to enlarge or shrink a mounted file system located on
device. This
feature is only available on the kernel supporting on-line resizing. Resizing
for unmounted file systems are not supported at present.
The
size parameter specifies the requested new size of the filesystem.
The
size of the filesystem may never be larger than the size of the
partition. Optionally, the
size parameter may be suffixed by one of the
following units designators: ´s´, ´K´,
´M´, ´G´, or ´T´, for 512 byte
sectors, kilobytes, megabytes, gigabytes, or terabytes, respectively. If
size parameter is not specified, it will default to the size of the
partition.
This program does not manipulate the size of partitions. If you wish to enlarge
a filesystem, you must make sure you can expand the size of the underlying
partition first. This can be done using
fdisk(8) by deleting the
partition and recreating it with a larger size or using
lvextend(8), if
you are using the logical volume manager
lvm(8)
If you wish to shrink a nilfs2 partition, first use
nilfs-resize to
shrink the size of filesystem. Then you may use
fdisk(8) to shrink the
size of the partition. When shrinking the size of the partition, make sure you
do not make it smaller than the new size of the nilfs2 filesystem.
This command is valid only for mounted NILFS2 file systems, and will fail if the
device has no active mounts.
