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.
