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 filesys-
       tem.

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.
