NILFS-RESIZE(8) System Manager's Manual 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 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 pa‐
   rameter 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.
