       nilfs-resize - resize NILFS file system volume size

       nilfs-resize [options] device [size]

       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

       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

       This command is valid only for mounted NILFS2 file systems, and will
       fail if the device has no active mounts.

       -y, --yes, --assume-yes
              Assume Yes to all queries and do not prompt.

       -h, --help
              Display help message and exit.

       -v, --verbose
              Verbose mode.

       -V, --version
              Display version and exit.
