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, magabytes, 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.
