FSADM(8)                                                              FSADM(8)

NAME
       fsadm -- utility to resize or check filesystem on a device

SYNOPSIS
       fsadm [options] check device
       fsadm [options] resize device [new_size]

DESCRIPTION
       fsadm  utility  checks or resizes the filesystem on a device.  It tries
       to use the same API for ext2, ext3, ext4, ReiserFS and XFS filesystem.

OPTIONS
       -e|--ext-offline
              Unmount ext2/ext3/ext4 filesystem before doing resize.

       -f|--force
              Bypass some sanity checks.

       -h|--help
              Display the help text.

       -n|--dry-run
              Print commands without running them.

       -v|--verbose
              Be more verbose.

       -y|--yes
              Answer "yes" at any prompts.

       -c|--cryptresize
              Resize dm-crypt mapping together with filesystem detected on the
              device.  The  dm-crypt  device  must  be  recognizable by crypt-
              setup(8).

       new_size[B|K|M|G|T|P|E]
              Absolute number of filesystem blocks to be in the filesystem, or
              an  absolute  size  using  a  suffix  (in  powers  of 1024).  If
              new_size is not supplied, the whole device is used.

DIAGNOSTICS
       On successful completion, the status code is 0.  A status code of 2 in-
       dicates  the operation was interrupted by the user.  A status code of 3
       indicates the requested check operation could not be performed  because
       the  filesystem  is  mounted and does not support an online fsck(8).  A
       status code of 1 is used for other failures.

EXAMPLES
       Resize the filesystem on logical volume /dev/vg/test to 1000 megabytes.
       If /dev/vg/test contains ext2/ext3/ext4 filesystem it will be unmounted
       prior the resize.  All [y/n] questions will be answered 'y'.

       fsadm -e -y resize /dev/vg/test 1000M

ENVIRONMENT VARIABLES
       TMPDIR The temporary directory  name  for  mount  points.  Defaults  to
              "/tmp".

       DM_DEV_DIR
              The  device  directory  name.  Defaults to "/dev" and must be an
              absolute path.
