NILFS-RESIZE(8)NILFS-RESIZE(8)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 resiz‐
ing. 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, magabytes, gigabytes, or terabytes, respec‐
tively. 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.
