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

SYNOPSIS
       fsadm [options] check device

       fsadm [options] resize device [new_size[BKMGTEP]]

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.

       new_size
	      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
       indicates  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.
